tubercle at the dorsal extremity, and from four to six smaller spine-like tubercles along its curve. The central ridge or tubercle is separated from the lateral ridge by a distinct furrow, and its continuation from the base of the tubercle passes between the lower ends of the two lateral ridges. Ventral and lateral margins with a narrow thickened rim.

This species resembles very nearly the B. tuberculata of Kloden, as described and figured by Mr. T. Rupert Jones. In our specimens the dorsal angles are more rounded; the posterior ridge at its base is never extended beyond the middle of the valve, and is marked on its crest by several small spine-like tubercles. The anterior ridge is usually more extended along the ventral margin in our specimens, aud the furrow is better defined, while the tubercles are never flattened above or overhanging the base as shown in the European specimens. Smaller specimens, which appear to be the young of this species, present some slight variations of surface markings, but show less difference than the young of B. tuberculata.

34. BEYRICHIA EQILATERA. N. sp. Fig. 20.

Nearly equilateral, very convex, marked by three smooth or nearly smooth ridges. The central ridge is an oblong tubercle reaching from near the dorsal margin a little more than half way to the ventral margin. The posterior ridge is a little larger, but scarcely differing in form from the anterior one, its ventral extremity terminating beneath or a little in advance of the middle of the central tubercle. The furrow is narrow but well defined on the two sides of the central tubercle, and becoming shallow in its passage to the marginal furrow; ventral and lateral margins thickened.

35. LEPERDITA SINUATA. N. sp.

Minute sub-ovate, anterior end narrow, dorsal line one-third shorter than the length of the valve; an extremely minute tubercle near the anterior end. Centre extremely convex or ventricose; ventral margin near the posterior end a little sinuous, or indented from the inner-side. Surface smooth under an ordinary lens.

Two specimens only of this species have been observed, both of them having the same dimensions.

36. TENTACULITES DISTANS. var.

The specimens under examination do not present any important points of difference from those of the Clinton group in New York. In the Nova Scotia specimens there are numerous annulations near the apex, which are not observable in the New York speci

mens.

37. HELOPORA FRAGILIS, var. ACADIENSIS.

The specimens under examination offer no very important difference from those in New York, and as the Nova Scotia examples have been more or less compressed and worn, they are scarcely in a satisfactory condition for nice discrimination.

All the above fossils belong to the Arisaig series of Mr. Dawson's paper. Nos. 4, 10, 30, 36 and 37 appear characteristic of the dark and olive shales of the lower member, in which are also Strophomena profunda, S. rugosa, Orthis testudinaria, Atrypa emacerata, Rhynconella equiradiata, Graptolithus Clintonensis, and crinoidal columns; also a Modiolipsis allied to M. subcari natus. The remaining species are in the coarse limestone and reddish shale of the upper member, in which are also Strophomena corrugata, Atrypa reticularis, Rhynconella neglecta, Lingula oblonga, Bucania trilobita, and a Chatetes or Stenopora similar to that of the Clinton formation. Cornulites flexuosus is almost the only species which occurs equally in both groups of beds. Some of the Clidophori are also found in both groups.

REVIEW.

NOTES of a Clerical Furlough, chiefly spent in the Holy Land, with a sketch of the voyage out in the Yacht "St. Ursula." By Robert Buchanan, D.D. Third thousand. Glasgow, Blackie & Sons : Montreal, B. Dawson & Son. pp. 437, with illustrative maps.

This book is written by one of the most esteemed and accomplished ministers of Glasgow, Scotland. It is the fruits of a voyage in the private yacht of Mr. Tennant, a wealthy manufac

turer of that city. The incidents of the voyage are most agreeably related. The party landed at Alexandria in Egypt, and visited Cairo and the Pyramids, of which places the author gives most graphic descriptions. Returning to Alexandria, they went on to Jaffa―the ancient Joppa, the port of Palestine. From that place they journeyed to Jerusalem. At every prominent place, vivid and most interesting descriptive accounts are given of the physical appearances of the country, together with interesting notices of the historical events associated with the localites. Instead of entering Jerusalem by the Jaffa Gate, the travellers took a detour to the Mount of Olives, which after much fatigue, they reached at night-fall, and spent a cold and comfortless night in an upper room in the Mohammedan Mosque. This, however, was the finest point for viewing the city and its environs. In the morning they descended the Mount, and wended their way along the road which the Saviour frequently traversed on His journeys to and from Jerusalem. The remarkable spots on this route, and the language of Scripture which they illustrate, are carefully noted. We have read nothing more artistic and eloquent than the descriptive parts of this entrance into Jerusalem, Having spent some time in the sacred city, and having visited the Dead Sea and the River Jordan, our travellers extended their journey northward through the classic ground of Samaria, on to the sacred Sea of Galilee. Here, with loving reverence and deep emotion, they linger among the scenes in which so many of the Lord's wonderful miracles were wrought. They went on to Lake Merom and the sources of the Jordan; and visiting Damascus, they then crossed the range of Lebanon, and examining the ruins of Baalbec, passed on to Tripoli, where they embarked again for home. While this book aims only at a familiar narrative of what was seen and experienced in Palestine, it yet exhibits an extensive and accurate erudition. If not so elaborate, it is as accurate and critical as Stanley's. In his powers of impresssing the prominent features of a scene, with its most interesting accessories, vividly upon the mind of the reader, Dr. Buchanan excels any of the late writers on the Holy Land. We know of no more fascinating or delightful book of travels than this is, and would specially recommend it as most suitable for the family library..
