"370 HAMINEA. 



The " Bulla ferruginosa Chemn." or rather, Gmelin (Syst., p. 

 3432) is a young Cyprcea. 



H. PERFORATA Philippi. Unfigured. 



Shell ovate-rotund, thin, pellucid, white, sculptured with very 

 fine transverse lines; vertex umbilicated ; aperture dilated at base; 

 inner lip forming an umbilical fissure. 



Alt. 8, diam. 5 lines. (Ph.). 



Manila (Largilliert). 



Bulla perforata PHIL., Zeitschr. f. Mai. 1847, p. 122. B. elegans 

 A. AD. (description, not figure), Yhes. p. 580. Not B. elegans 

 Gray. 



Very like B. hydatis and B. ovoidea; differing from the first by 

 the umbilical fissure ; from ovoidea in the less narrow mouth dilated 

 at base. (Ph.). 



Adams' description is copied from Philippi, but his figure repre- 

 sents the West Indian H. elegans Gray. Sowerby describes and 

 figures the true elegans, but quotes Arthur Adams as authority for 

 that name, and retains the borrowed locality " Manila." There is 

 of course no occasion whatever for confusing the West Indian H. 

 elegans with the oriental H. perforata; the characters and locality 

 given by Philippi amply distinguishing his species.
