The rather convex whorls, the oblique and slightly flexuous ribs and the 

 close fine spiral striae, are the principal features of this specie.^. It seems to 

 be variable in colour, some specimens being entirely white, others reddish or 

 brownish. Some white examples have a brown zone below the suture and 

 another round the middle of the body-whorl, and one pale specimen has 

 some distant, obscure, reddish spots upon the upper part of the whorls. 

 The spiral striae are most conspicuous between the costae. 



Drillia subeontraeta, n.sp. 

 PI. ii, fig. 2. 



Testa elongata, fusca, ad apicem mamillata, anfractus 8, superiores duo 

 laeves, convexi, caeteri supra concavi, infra convexi, costis obliquis circiter 

 12, supra attenuatis, instructi, inter costas spiraliter fortiter striati, ultimus 

 infra medium contractus, et costis obsoletis circa basim sulcatus ; apertura 

 sub-ovalis, supra et infra contracta, longit. totius circiter ^ aequans ; labrum 

 tenue, baud profunde sinuatum : columella oblique arcuata, callo tenui pallido 

 induta. 



Longit. 12 millim., diani. 4.5 : apertura 4 millim. longa, 2 lata. 



The body-whorl is well rounded at the middle and then contracted 

 below. A spiral striation or groove at the periphery, which also winds up 

 the spire just above the suture, is usually more strongly marked than the rest.
