ZEMIRA. 213 



E. SEMIPICTA, Sowb. PI. 82, fig. 4t0. 



Epidermis yellowish. The two-banded arrangement of the 

 spots and absence of superior row of blotches will serve to dis- 

 tinguish this species. Lengtli, I'T inches. 



Habitat unknoiim. 



E. PERFORATA, Sowb. PI. 82, fig. ill. 



The deep, wide channel, short rounded whorls, turbinate spire, 



very wide umbilicus, with tuberculate margin and central callus 



deposit, and above all the peculiar zebra-like coloring, will serve 



to distinguish this species. Length, 2 inches. 



Habitat unknown. 



E. AMBULACRUM, Sowb. PI. 82, fig. 412. 



Very deeply channelled, with short whorls, somewhat flattened 

 upon the upper half; color darker than in the other species in 

 consequence of the color blotches and spots nearly covering the 

 entire surface. Length, 1*5 inch.

 short ; umbilicus narrow, covered with callus. Color lilve that of 

 E. sjjirata. Length, 1"15 to 2*25 inches. 



Persian Gulf ; Bed Sea. 



Yon Martens considers this merely a short form of .£'. spirata^ 

 and it is qOite possible that such is the case, although the three 

 figures which he gives I would refer without doubt to Valentini- 

 ana. I cannot adopt the Chemnitzian name MoUiana, because 

 he was not a binomial author. 



Suhgcnns ZEMIRA, II.MndA. Adams. 



The revolving chaunel near the base of the shell, ending in a 

 tooth-like projection on tlie outer lip, has induced Sowerby to 

 class this species in the genus PHevdoJiva : it seems nearly 

 related to Ehurna, however. 



E. AusTRALis, Sowb. PI. 82, fig. 474. 



Shell covered by revolving incised lines ; epidermis very thin, 

 yellowish ; irregularly brown spotted, spots usually more promi- 

 nent on the shoulder border, Length, •(Ui inch.
