This species is smaller than E. spirata, has fewer spiral 

 threads, and the whorls are not tabulated or channeled at 

 tiie u|>per ])art. The figure in the ' Samarang,' like others 

 on tiie same plate, is greatly enlarged, the type being only 

 28 mm. in length, and that given by Melvill & iSykes in 

 lfc'98 was taken from Adams's type of E. cumingii. In 

 Dr. J. E. Gray's collection, preserved in the British Museum, 

 is a still larger specimen, which, if the spire were perfect, 

 would mea.sure 40 mm. in length, and its last whorl is 

 11'25 mm. in width. It is worthy of notice tiiat even a 

 greater disparity in size occurs in specimens of Mesalia 

 brevialis. 



With regard to E. leptomita, I have no hesitation in 

 regarding it as identical with tn'carinata^ notwithstanding 

 tiie reujarks offered by Messrs. Melvill, Standen, and Sykes. 

 Tiiey ob.serve that " tlie type has five c;iriii£e at least on tiie 

 last whorl, and ' tricar (nata^ is therefore an inappropriate 

 name." On reading the original description, it is seen that 

 this character is an allusion to the three priiicij)al keels on 

 the upper whorls, and the authors, Melvill & Sykes, employ 

 the same word in the description of leptomita. They say 

 that the last whorl is " quiidricaiinato.'^ This is incorrect, 

 for an examination of their type shows that there are six 

 carinse, as described by A. Adams in E, cumimjii. There 

 are four principal keels, and above these two others, the 

 upper one nearly at the suture, which consequently is chan- 

 nelled. 



In the Proc. Zool. Soc, ]\Ielvill & Standen observe that 

 " tlie extremes seem distinct from E. carinata, Ad. & Rve., 

 but the sj)eties is evidently, though rare, \i^\y widely distri- 

 buted, aid intermediates may, in time, be found to occur." 

 The italics are mine. Since I can discover no differences in 

 leptoniita, the future need not be taken into consideration. 



Turrilella cunsperso, Adams & Reeve, placed by Tryon as 

 a variety of the present Sjiecies, is a true Tunitdla, and 

 entirely distinct in every respect.
