16 TEREBRA. 



T. SENEGALENSIS, Lam. PL 3, figs. 41-45 ; PL 12, fig. 33. 



Shell with a subsutnral band, surface varying from nearly 

 smooth, showing only longitudinal flexuous growth-stria?, to 

 longitudinally plicate; yellowish white, more or less inter- 

 ruptedly three-banded with pale or dark chestnut or chocolate, 

 four or five bands on the body-whorl; sometimes the darker 

 coloring suffuses the entire surface. Length, 3-4 inches. 



Senegal, etc., West Africa. 



It is T. striatula, Lam., T. fu.scomacula.ta, Sowb. ; probably 

 T. pugio, Gmel., T. f estiva, Desh. (fig. 45), T. speciosa, Desh. 

 T. raphanula, Lam. (PL 12, fig. 33), said to occur at Amboina, 

 has the markings somewhat tessellately arranged ; a good series 

 of specimens easily connect it with the typical coloring. 



T. CINGULA, Kiener. PL 12, figs. 2T, 28. 



First whorls plicately ridged, the rest smooth, with a more or 

 less defined sutural band ; light fawn-color, encircled by two or 

 three rows of chestnut blotches, forming interrupted bands. 



Length, 3 inches. 



Senegal (Kiener) ; St. Christopher, W. I. (Miller). 



Closely allied to, and perhaps only a variety of, the preceding

 more faded in coloring. 



T. PURA, Deshayes. PL 12, fig. 30. 



Whitish, shining; obsoletely banded at the suture by an 

 impressed groove, obliquely longitudinally plaited, plaits rather 

 distant, thin, gradually fading towards the aperture. 



Length, 2*5 inches. 



m Zanzibar. 



T. TROCHLEA, Desh. PL 12, fig. 35. 



Longitudinally plicate, a depressed sutural band separated by 

 a broad, profound sulcus, from the rest of the whorl, which is 

 convex, this band is nodulous, the nodules becoming evanescent 

 on the last whorl; maculate and flammulate with chestnut and 

 white. Length, 65 mill. 



T. DUSSUMIERI, Kiener. PL 3, figs. 46-48. 



Closely narrowly longitudinally plicate, the ridges becoming 

 partially obsolete on a subsutnral band; pale chestnut with a
