130 Mr. G. E. Dobson on Dr. Severtzof's 



are nearer the base or the apex), each with a row of broad, 

 acutely angular cell-denticles, seven in the space of 3 lines ; 

 the upper edge of each cell slightly convex and nearly at right 

 angles with the back, and rather longer than the undivided 

 portion, the lower edge two thirds uncovered by the next cell, 

 and making an angle of about 45° with the back ; from the 

 point of one cell to the next about equal to the width from 

 the same point to the back. The whole polypidom, of about 

 forty stems, forms a slightly quadrate circle or rounded square 

 about 2 inches in diameter. 



Rare in the black and red slates, of the Llandeilo-Flag age, 

 of the Bendigo goldfield, Sandhurst, Victoria. 



I name this species after the discoverer, M. Thureau, of 

 Sandhurst, who first brought it under my notice. The regular 

 zigzag bendings of the four branches of the funicle, from which 

 the stems arise, easily distinguish it from any other with which 

 I am acquainted. For those writers who prefer to break up the 

 genus Didymograpsus^ the name Goniograptus might be sug- 

 gested for such types as the present, in which the branches 

 of the funicle (for which I would suggest the name stolons) are 

 angularly bent at the points of budding into the celluliferous 

 stems. 1 have, &c..

XIV. — Observations on Dr. Severtzoff'' s ^^ Mammals of Tur- 

 kestan " [translated hy F. Carl Craemers)'^. By G. E. 

 Dobson, M.A., M.B., F.L.S., &c. 



The thanks of zoologists are due to Mr. Carl Craeraers for 

 having made known to them by his translation the highly 

 interesting observations of Dr. Severtzoff on the mammals of 

 Turkestan ; for Russian is practically an unknown language to 

 most zoologists of Western Europe, and Turkestan almost an 

 unexplored region as regards its fauna. As I have lately 

 published a monograph of the Asiatic Chiropteraf, and am 

 at present engaged in preparing descriptions of the Chiroptera 

 collected by the late Dr. Stoliczka during the expedition to 

 Western Yarkand, I wish to make some observations on the 

 nomenclature adopted by Dr. Severtzoff, and on his determi- 

 nations of some of the species.
