Hob. On the plains within 50 miles of Mamboia. 



One of the four specimens of this species is somewhat 

 stumpier than the others and has the aperture closed with a 

 firm white epiphragm. 



BuUmus {Cerastus) Lasti. 



Testa ovata, superne producta, late perforata, subpeUucido-albida, 

 epidermide tenuissima pallide flava induta, nitida, oblique con- 

 fertim et regulariter striata ; anfract. 7, convexi, sutura profundi- 

 uscula, fere horizontali, sejuncti, ultimus inferne leviter saccatus, 

 striis ad basim productis ; apertura ovata, superne acuminata, 

 antice rotundata, longit. totius ^ subaequans ; perist. tenue, 

 margine columeUari late expanse et reflexo ; spira obtuse conica, 

 ad apicem baud acuta. 



Longit. IS millim., diam. maj. 11, min. 10; apertura 8 longa, 5 

 lata. 



Hah. Same as B. mamhoiensis. 



This is a much shorter species than B. mamhoiensis, with 

 the aperture rounder below, the sculpture on the body- 

 whorl continued equally strong to the base, the umbilicus 

 slightly larger, and the columellar reflexion broader. 



Bulimus {Cerastus) Emini. (PL V. fig. 8.) 



Testa BuJimo Lasti persimilis, diflPert apice magis acuminate, aper- 

 tura magis perpendiculari, anfractibus striis vel lineis spiralibus 

 ornatis. 



Longit. 19 millim., diam. maj. 11, min. 10\; apertura S longa, 

 5 lata. 



Hah. Hkata, Kidete, Htoni Hiranza {Emin). 



Although very like B. Lasti in form, 1 think there is little 

 doubt that this species is distinct. On comparison the spire 

 is seen to be more pointed, the aperture less lateral, and the 

 whorls exhibit numerous fine, transverse, white lines, which 

 seem to be in the texture of tlie shell and are more plentiful 

 in some specimens than in others. They are scarcely visible 

 to the naked eye.
