178 Canon A. M. Norman on 



ignorant of Studer's work of 1789, describes another Pomatias, 

 and uses Cyclostoma patulum as the type." 



Is not this another mii^apprehension? Did it not strike 

 Mr. Newton as remarkable that Hartmann should have coined 

 a name identical with that of Studer for the same genus, and 

 is he aware that in the same year, 1821, Hartmann (' Neue 

 Alp.' p. 214) actually named a species P. Studeri? 



This statement in Mr. Newton's first paper is surpassed by 

 the following sentence in his second paper : — " He \j. e. 

 Norman] appears to be only anxious to demonstrate that we 

 should follow the opinion most generally received by concho- 

 logists on this subject [i. e. in retaining Ct/c/ustoma] , instead 

 of thinking it a matter for congratulation that the discovery 

 of the Studerian genus now relieves us from the difficulties 

 that have surrounded Gyclustoma for upwards of ninety years." 

 This sentence appears to admit of no other interpretation 

 than that, as Studer's genus Pomatias was according to Mr. 

 Newton unknown to Hartmann, so, according to him, it has 

 remained unknown to conciiologists until 18'Jl, when it was 

 discovered by himself! 1 take down all the works from my 

 library which 1 remember to contain Pomatias of Studer (as 

 used for P. variegatus and allies) or of Hartmaim, and give 

 the following result of the ways in which this genus is quoted 

 by those writers : — 



^^Pomatias, Studer " {sic) : thus used in Adami, Cristofori 

 and Jan, Charpentier, Stabile, Du|niy, Brusina, H. 

 and A. Adams, S. P. Woodward, Kubelt, Clessin, 

 Westerlund. 



"Pomatias, Hartmann " (sic) : Pini. 



" Pomatias J Hartmann non Studer ^^ (sic) : Moquin-Tandon. 



"Pomatias {Studer 1789) , Hartmann 1821" {sic): Paul 

 Fischer. 



In this last reference Fischer puts the matter in a nutshidl. 

 The genus is the genus I'omatias of Studer, and he uses it in 

 the restricted sense as employed by Hartmann. As I stated 

 in my last notes, Hartmann, when he discovered Pomatias, 

 Studer, acted very wisely in leaving the well-established 

 Cyclostovui undisturbed and in applying Pomatias to the 

 group for which he wished to linda name, and which inclnded 

 the second species mentioned by Studer. His action, more- 

 over, was fully in accordance with the later Brit. ^Vssoc. 

 rules, and cannot lawfully be altered.
