 ANCILLARIA. 93 



with the Olives, and in its frequently horned outer lip it also 

 reminds one of Pseudoliva, and Eburna (Zemira) australis. 



I have merged in Ancillaria several subgeneric groups of H. 

 and A. Adams and others, which do not appear to me to possess 

 substantial distinctive characters. 



A. CINNAMOMEA, Lam. PL 37, figs. 2-17. 



Yellowish white, with obscure revolving bands and longitudinal 

 strigations of light reddish brown, or without markings, and 

 ranging from flesh-color to cinnamon and dark chocolate ; 

 occasionally a revolving sutaus terminates in a slight horn on 

 the outer lip ; the folded columella is white, the interior of the 

 aperture nearly corresponding with the outer surface in color. 



Length, 1-1-25 inches. 



Red Sea, Persian Gulf, Zanzibar. 



I unite here several so-called species. A. cinnamomea is not 

 quite adult, and more frequently exhibits the lip-tooth than the 

 adult, heavily-callused A..ventricosa, Lam. (fig. 3). A. variegata, 

 Sowb. (fig. 4), is the light, banded form described above, and A. 

 fulva, Swn. (fig. 5) has similar painting. Other synonyms are : 

 A. albifasciata, Swn. (fig. 6 , A. albisulcata, Sowb. (fig. 7), in 

 which the impressed groove is white, a character without 

 constancy, A. achatina, Kiener (fig. 8), A. striolata, Sowb. (fig. 

 9 N , a juvenile, A. castanea, Sowb. (fig. 10\ A. ovalis, Sowb. (fig. 

 11), another juvenile, A. Desliayesii, A. Ad. (fig. 12), A. crassa, 

 Sowb. (fig. 13), A. sarda, Reeve (fig. 14), A. contum, Reeve (fig. 

 15), apparently a worn specimen, A. eburnea, Desh. (fig. 16), A. 

 Tronsoni, Sowb. (fig. 17). 



A. ACUMINATA, Sowb. PL 37, figs. 18-20. 



Yellowish brown, lighter at the sutures and on the border of 

 the fasciole, the latter being darker brown, columella white. 



Length, 1 '25-1 '5 inches. 



Red Sea, Zanzibar. 



The narrower form is the only, and perhaps not sufficient 

 distinction between this and the preceding species. A. lineolata, 

 A. Ad. (fig. 19), and probably A. oryza. Reeve (fig. 20), are 

 synonyms. 



A. MARMORATA, Reeve. PL 2, figs. 21, 22. 



Whitish, faintly streaked and mottled with fulvous flesh-color,
