Descriptions of New Species. 



Tubbonilla erubesceits, nov. spec. PI. v. fig. 10. 



Shell of the same dimensions as T. fusca, Adams ; from 

 which it differs in the more numerous and less regular 

 transverse costse ; its colour is a transparent light-horn, and 

 & narrow rufous band winds round the centre of the whorls. 

 On the body whorl a similar band is situated below the 

 periphery. The columella lip is ruby-tinted. 



It agrees in its coloration with T. /estiva, Angas, but that 

 shell is not coloured on the columella, and its whorls are 

 rounder, aperture wider, and the suture less impressed. 



Dimensions of a shell of ten whorls : — Length, "25 ; breadth, 

 '05 inch. The relative proportions of the length to the 

 breadth are in T. erubescens 40 to 8, and in T. f estiva, 40 to 15 , 



Uteiculus apiculatus, spec. nov. PI. v. fig. 3. 



Similar to U. eumicrus, Crosse, but distinguishable by its 

 sunken spire, the papillary apex of which is exserted beyond the 

 level of the body whorl. The anterior extremity of the shell is 

 more gradually tapering, and the shoulder of the body whorl is 

 less abruptly arched, consequently U. apiculatus is, more fusiform 

 than its ally. It is also much larger.

 green, and the muzzle and upper side of foot is black.

 and sutural constrictions ; very thick. Colour, yellowish- 

 white or grey, with surface marked with curved striae of 

 growth, and under the lens with numerous longitudinal striae.
