ANCILLARIA. 93 



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

 reminds one of Pseudoliva, and Ehiirna {Zeviira) aifstralis. 



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. PI. 3*7, figs. 2-1*7. 



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 sulcus 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 "2.5 inches. 



Bed Sea, Persian Gtilf, Zanzibar. 



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



quite adult, and more frequentl}' exhibits the lip-tooth than the 



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



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



fidva^ Swn. (fig. 5) has similar painting. Other synonyms are: 



A. albifasciata^ Swn. (fig. 6 , A. alhisulcata^ Sowb. (fig. 1), in 



which the impressed groove is white, a character without 



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



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



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



Sowb. (fig. 13), A. sarda, Reeve (^fig. 14), A. contusa, Reeve (fig. 



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



Tronsoni^ Sowb. (fig. 17'. 



A. ACUMINATA, Sowb. PI. 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. 



Bed Sea, Zanzibar. 



The narrower form is the only, and perhaps not suflBcient 



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



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



synonyms. 



A. MARMORATA, Recvc. PI. 2, figs. 21, 22. 



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