^70 HAMINEA. 



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

 3432) is a young Cyprcea. 



H. PERFORATA Philippi. Unfgured. 



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

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

 inner lip forming amimbilical fissure. 



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



Manila (Largilliert). 



Bulla perforata Thil., Zeitschr. f. Mai. 1847, p. 122.— 5. elegans 

 -A. Ad. (description, not figure), Thes. p. 580. Not B. elegans 

 Gray. 



Very like B. hydatis and B. ovoidea; diflfering 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 II. 

 e/er/rn/s with the oriental H. perforata; the characters and locality 

 given by Philippi amply distinguishing his species.
