ANCILLARIA. 95 



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



Narrowly cylindrical, transparent fawn-color, callosity and 

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



China. 



Possibly the 3'oung 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 yonng 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. PL 38, figs. 37, 38. 



Shell thin, whitish, j-ellowish or pale cinnamon-color, with a 



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



the fascicle. Length, 2-2*5 inches. 



N. 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. Tankervillei, 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}- probably equivalent to A. rubiginosa, 

 Swn. A. 2\ova-Zelandica, Sowb. (fig. 42), is a sj'uonym, and I 

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

 placed here.
