PSEUDOSTROMBi: S. 1 5 



Kiener, who figures this species as Bucc. vittatum, Linn., con- 

 founds with it B. melanoides, a shell from the opposite coast of 

 Africa, and quite distinct, judging from the specimens before me. 

 Lamarck considered it a Terebra^ a genus to which this shell is 

 closely assimilated by its usually very narrow form, polished 

 surface and sculpture. 



B. POLITA, Lam. PI. 6, figs. 88, 89. 



Cream-color, yellowish brown or livid olive, with frequently a 

 very indistinct darker band near the suture; whorls of the apex 

 plicate, rest smooth and polished. Length, 1-1*25 inches. 



Senegal. 



B. mtrea, Reeve (fig. 89), is synonymous. 



B. KURRACHENSIS, Augas. PI. 6, fig. 90. 



White, tinged with rose-color on the upper whorls. 



Length, l'T5 inches. 



KurracMj Scinde, N. W. India. 

 Only the type specimen known. 



B. VITTATA, Linn. PI. 6, figs. 87, 92. 



Yellowish or lilac-white, or bluish or brown; sometimes the 

 spire is clouded bluish whilst the rest of the shell is light colored. 

 Sutural plications defined by an incised revolving line and some- 

 times cut in two by another line. Length, 1 '5-1 '75 inches. 



Ceylon; Zanzibar. 



B. livida, Reeve (fig. 92), is only one of the many slight vari- 

 ations which can be readily traced to the typical form. This 

 species occasionally develops a varix on the outer lip, and speci- 

 mens are before me in which a former varix is persistent. 



B. TAHEITENSIS, Gmelin. PI. 6, fig. 93. 



Spiralty ridged, ridges finely granose, two or three ridges next 

 the suture more distant than the rest; yellowish, maculate with 

 orange-brown, interior of aperture brown stained. 



Length, T75 inches. 



Taheiti. 



A very rare species, and the only one having its pattern of 

 sculpture. The figure in Chemnitz is evidently poorly drawn,* 

 and there can be no doubt that the British Museum specimen, 

 figured by Reeve, is a better representation of the species, as it 

 more nearly approaches a specimen now before me.
