Terebra bacillus. Ter. testa aciculari, alba, cinereo- 

 plmnbeo plus minus fasciatd, nitente, infra suturas in- 

 terdum maculatd, apice plumbed, a nfractibus declivi- 

 planatis, indivisis, superne elongate" plicato-crenulatis;

The little staff Terebra. Shell aciculnr, white, more 

 or less banded with leaden ash-colour, shining, some- 

 times spotted beneath the sutures, apex lead-colour,

Species 135. (Fig. a, b, c, d, Mus. Cuming.) 



Terebra micans. Ter. testa aciculari-subulatd, nitente- 

 albd, interdum lutescente, purpureo-brunneo fasciatd, an- 

 fractibus decliri-planatis, indivisis, superne dense elon- 

 gate plicato-crenulatis ; aperturd parvd, columella ap- 

 presse arcuatd, brevi. 



The glittering Terebra. Shell acicularly subulate, 

 shiniug-white, sometimes yellowish, banded with rich- 

 brown, whorls slopingly flattened, undivided, densely

 Terebra Adansoni, Deshayes. 



Hab. Senegal. 



The typical peculiarity of this and the preceding species 

 consists in the whorls not being divided by any spiral 



grooves, but densely puckered from the suture with fine 

 elongated crenules. 



Species 130. (Mus. Cuming.) 



Terebra aficina. Ter. testa aciculari, nitente-albd, infra 

 suturas maculis rnjis super fasciam limdo-carneam 

 cingulatd, aufractibits decliri-planatis, indivisis, su- 

 perne elongate plicato-crenulatis ; aperturd parvd, colu- 

 mella appressi arcuatd, bred . 



The sharp-pointed Terebra. Shell acicular, shining- 

 white, encircled below the sutures with red spots 

 upon a livid-flesh band, whorls slopingly flattened, 

 undivided, elongately plicately crenuled round the 

 upper part ; aperture small, columella appressly 

 arched, short. 



Deshayes, Pro. Zool. Soc. 1859, p. 284. 



Hab. Singapore. 



In this example of the same type the elongated crenules 

 are larger, over a livid-flesh band, and a necklace of bright- 

 red spots. 



Species 137. (Mus. Cuming.) 



Terebra DISPAR. Ter. testa aciculari-subulatd, nitente- 

 albd, semipellucidd, a nfractibus decliri-planatis, indi- 

 visis, superne dense plicato-crenulatis ; aperturd ob- 

 longo-ovatd, columella appresse arcuatd, breviusculd. 



The unlike Terebra. Shell acicularly subulate, shin- 

 ing-white, semitransparent, whorls slopingly flat- 

 tened, undivided, densely plicately crenuled round the 

 upper part ; aperture oblong-ovate, columella ap- 

 pressly arched, rather short.

Sab. •? 



This species bears very closely on T. micans. It is more 

 slenderly convoluted, and the crenules are stronger and 

 shorter.
