 Bulimus citriiius, var. B. Bruguiere, 314. 27. 



A. FINE pair of this beautiful and rare variety is in the collec- 

 tion of Mr. C. Dubois, to whom I am indebted on this and 

 many other occasions, for the facilities he has afforded me in pro- 

 secuting the present work : one of these is now figured ; it dif- 

 fers in no respect from that in the last plate, except in being re- 

 versed and having the umbilicus not so completely closed ; a cha- 

 racter which, perhaps, exists only in very old shells. The other spe- 

 cimen is also reversed and banded, though in a different manner. 



BULIMUS aureus. 



Golden Bulimus. — upper and lorcer figures.

Having seen but a single specimen of this shell, I have placed 

 it as a distinct species, not without some doubts, and principally 

 for the purpose of calling the attention of conchologists to a more 

 rigid examination of the specific distinctions of this family (un- 

 connected with colour) than has heretofore been done. Tiie re-
