BULIMUS citrinus, (w/r.) 



Citron Bulimus, (3 varieties.) 



Generic Character. — See PI. 4. 



Specific Character. — See PL 46. 



Varieties. 



A. Yellow, with black lines. Zool. III. pi. 46. 



B. Yellow, with black lines and chesnut stripes. Zool. III. p. 47. 



C. Yellow, variegated with green; inner lip obsolete. Fig. 1. 



B. virescens. Sio. Bligh Cat. p. 13. 



D. Green, striped with yellow ; inner lip white. Fig. 2. 3. 



E. Orange, with flame-coloured waved stripes. Fig. 4. 



F. Pale yellow, with brown waved stripes. 



The beautiful shells here selected as a further illustration of 

 the Citron Bulimus not only show the great variability of the 

 species, but clearly prove that B. virescens is, as I suspected, 

 only a variety of ^. citrinus. In the shell at fig. 1. the upper 

 part of the inner lip (like that described in the Bligh Appen- 

 dix), is entirely wanting ; although it bears, in every other 

 respect, the appearance of a full-grown shell; the umbilicus 

 likewise is open; but in the shell at fig. 2. and 3. the inner 

 lip is quite perfect, and consequently folds over the umbilicus; 

 thus the connexion between the green and yellow varieties is 

 completely established. 



I have subjoined a slight arrangement of the principal 

 varieties ; and have only further to observe, that the specific 

 character I first proposed, appears to me the only one by 

 which this species may be truly distinguished. 



Since the description of B. aureus at pi. 47 was written, 

 I have seen several other specimens ; all of which tend to 

 confirm my belief that it is distinct from B. citrinus.
