ANCILLARIA. 95 



A. ANGUSTATA, Sowb. PI. 38, fig. 35. 



Narrowly cylindrical, transparent fawn-color, callosity and 

 fasciole shining orange-brown, edged with white. Length, 12 mill. 



China. 



Possibly the young of A. rubiginosa, Sw., or of a similar 

 species. 



A. BULLIOIDES, Reeve. PL 38, fig. 36. 



Delicate fawn-color, callosity broad, opaque, white. 



Length, 28 mill. 



Habitat unknown. 



Perhaps a young shell of A. rubiginosa. The type specimen 

 only is known, and its peculiarly long spire might be an indi- 

 vidual variation of growth. 



A. CINGULATA, Sowb. PI. 38, figs. 3T, 38. 



Shell thin, whitish, yellowish or pale cinnamon-color, with a 

 white sutural band, and a revolving brown band above and on 



the fasciole. Length, 2-2'5 inches. 



JV. Australia, China ? 



Distinguished from A. rubiginosa by its thin substance and 

 inferior dark band. 0. similis, Sowb. (fig. 38), is probably a 

 faded variety. * 



A. TANKERVILLET, Swainson. PL 38, fig. 39 ; PL 39, fig. 40. 



Fusiformly oblong, moderately ventricose, yellowish white to 

 orange-yellow, darker about the sutures and on the fasciole. 



Length, 2'25-3*75 inches. 



West Indies. 



The only species inhabiting the Western Hemisphere. I am 

 not able to separate 0. Vernedei, Sowb. (fig. 40), described from 

 a single specimen, and doubtfully referred to China Seas as its 

 habitat. Specimens of A. Tankervillei before me agree exactly 

 with the figure of Vernedei, except that the latter is larger. 



A. SINENSIS, Sowb. PL 39, figs. 41-43. 



Transparent white, the callosity opaque white. Length, *8 inch. 



Japan, China, Australia. 



A juvenile shell, and ver} T probably equivalent to A. rubiginosa, 

 Swn. A. Nova-Zelandica, Sowb. (fig. 42), is a synonym, and I 

 suppose that A. inornata, E. A. Smith (fig. 43), may also be 

 placed here.
