PSEUDOSTROMBIS. 15 



Kiener, who figures this species as Burr, rittatum, Linn., eon- 

 founds with it B. melatwidt, :i shell from the opposite const 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. POLTTA, Lam. PI. f>, tigs. 88, 89. 



("ream-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. 



It. ritrea, Reeve (iig. 80), is synonymous. 



P>. KURRACRENBIS, Angas. PI. P>, Iig. 90. 



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



Length, I '75 inches. 



Kurradd, Scinde, N. W. 

 Only the type specimen known. 



15. VITTATA, Linn. PL 0, 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. TAHETTENSIS, Gmelin. PL 6, fig. 93. 



Spirally 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, 1/75 inches. 



TaJieiti. 



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.
