FROM TUB SOLOMON ISLANDS. 539 



angusta, lougitudinis totius testae ^ aequans ; labruui fortiter incras- 

 satmn, intus denticulos 10-11 geiens; columella rectiuscula granulis 

 et liris transversis munita. Long. 8 mill., diam. fere 3. 

 Hab. San Christoval, Solomon Islands. 



This is a very pretty species, and at once recognized by the 

 deep-brown suture, the band encircling the middle of tlie body- 

 whorl, which is continuous and not interrupted by the longi- 

 tudinal ribs, and the paler band towards the base. The spiral 

 lirations are almost equidistant, and slightly nodulous on travers- 

 ing the costse ; and the fine striations between them are from two 

 to four in number. The uppermost denticle within the labrum 

 (that is, the one wbich borders the little sinus) is somewhat larger 

 than the rest. The columella is furnished with numerous small 

 tubercles and transverse lirations, somewhat irregularly situated, 

 the former, however, being near the exterior margin of the thin 

 callosity which spreads out on the columella, and the latter further 

 within the aperture. This species has much resemblance to 

 Pleurotoma {Ciihard) Mclathrata of Souverbie, Journ. de Conch, 

 xxi. p. 59, and may eventually prove to be but a large variety 

 of it,

Hab. Tarawa Island, Gilbert group. 



This snow-white species has somewhat the form of Fl. vuUuosa, 

 Keeve. It is, however, rather longer in the body-whorl, the 

 longitudinal ribs are more numerous and slender, and the spiral 

 lirae are more distinct.
