doubt what shells Bolten intended to call Tritotiiuvi rubefa, founded 

 on Chemnitz figs. 1236-7. 



These evidently represent the red-mouthed form of the species 

 under discussion, and which I have indicated as typical. 



I propose therefore to use the specific name rubefa instead ot 

 latnpas which I have shown must be applied to the Mediterranean 

 '' Triton nodifemm " of Lamarck. 



The synonymy will consequently be as follows : — 

 Bursa (Tutufa) rubeta (Bolten).

It is curious that Bolten founded his Tritonium tuberosum on the 

 same figures in the Conchylien-Cabinet which he quoted as represent- 

 ing his T. rubeta. Although the latter name appears one page later, 

 I prefer to suggest its use, since it was proposed by Linnaeus, altliough 

 in a varietal sense. 



Some of the subdivisions of the genus Bursa do not appear to be 

 of much value or very clearly defined, and I have been in some doubt 

 with regard to the subgeneric name which should be applied to this 

 species. 



Bursa of Bolten is practically the equivalent of Rafiella of Cuvier 

 and Lamarck, and antedates it by nineteen years, and consequently 

 there is no difficulty as to what generic name should be employed. 

 Jousseaume^ selected from the species quoted by Bolten'', B. bufonia 

 Gmelin (^=jnammatn Bolten) as the type. 



The genus Latnpas was created by Schumacher** in 181 7 to in- 

 clude Murex lampas as illustrated by Chemnitz (Conch. Cab., vol. iv., 

 figs. 1 236-1 239), but that generic name had already been employed in 

 1808 by Montfort*, and therefore is not available. Jousseaume in 1881 

 founded a genus Tutufa, designating the same species, Murex latnpas 

 as the type.
