DESCRIPTIONS OF NEW SPECIES OF LAND SHELLS 

 FROM THE EAST COAST OF AFRICA. 



By John W. Taylor, 



I have pleasure in resuming the description and publication of 

 the various and interesting species collected by Mr. Gibbons in 

 East Africa. 



BuHminus Gibbonsi (PI. Ill, fig. i). 

 Shell broadly ovato-conical, thin, glistening, hardly semi-trans- 

 parent, of a light horn color^ strongly and very regularly striate 

 in the line of growth ; epidermis distinct, moderate ; whorls 

 6^-7 broad, ventricose ; the body-whorl very large ; the apex 

 blunt ; suture distinct ; aperture ovate ; outer lip thin, simple ; 

 inner lip reflected partly over the umbilicus ; anterior end of 

 mouth rounded ; umbilicus large and deep. 

 Length 0.625, breadth 0.375. 

 ' Hab. Mozambique. 



Two specimens only of this fine species were obtained on' 

 the mainland, Mozambique. One of the specimens, found beneath 

 a stone, was evidently only recently dead.
