SOUTH AFRICAN MARIXE MOLLUSCA. 33 



Dillvvyii appears to have been the inventor of the specific 

 name schroeteri and not Chemnitz. At present I am not 

 convinced that the two forms schroeteri and picta as 

 determined by Reeve (^ Conch. Icon./ vol. ii, figs. 167 and 123 

 respectively) are absolutely identical. The former seems 

 somewhat shorter and to have a broader aperture, the labruni 

 also having a tendency to be a little patulate. A difficult 

 question arises as to which form is the true schroeteri, but 

 at present I am inclined to agree with Mai'tens that the shell 

 known as picta of Reeve is that figured by Schroeter and 

 afterwards called Voluta schroeteri by Dillwyn. If this 

 be correct, then the Mitra schroeteri of Reeve, if distinct, 

 would require a fresh name. Until I have the opportunity of 

 examining a larger series of specimens in good conditiou I do 

 not think it advisable to attempt any further solution of the 

 difficulty. 



Mitra simplex Dunher. 



With this species Martens ('Tiefsee-Exped.,^ p. 53) unites 

 cinnamomea A. Adams. The latter, however, I have 

 reason to believe is Tasmanian, and does not occur in 

 Natal, iis stated by Adams. There are numerous specimens 

 in the British Museum from Oyster Cove, Tasmania, agreeiug 

 exactly with the types in every respect.
