156 Mr. E. A. Smith on Land- and 



The resemblance in form and the faint raised line around 

 the body-whorl recall to mind the typical form of SuhuUna 

 suhcarinifera. That species is imperforate, much more 

 coarsely sculptured, and has a more distinctly truncate colu- 

 mella. The apex in both forms is similarly introverted. 



Bidimus [Bulimmus) suholivaceus. 



Bulimimis olivaceus (Gibbons, MSS.), Taylor, Quart. Journ. Concb. 

 vol. i. p. 253, pi. ii. fig. 5. 



Hah. Bauri Island, Zanzibar {Taylor), 



Five specimens of this species were presented to the 

 British Museum by J. S. Gibbons, Esq., in 1876. The name 

 olivaceus being preoccupied by PfeifFer for a species from 

 Candia, I propose to designate the present species B. suh- 

 olivaceus^ the colour being decidedly pale olive. 



Bulimus {Rapalus) suhvirescens. (PL V. fig. 12.) 



Testa imperforata, elongata, tenuis, nitida, subpellucida, dilute 

 virescens ; anfract. 7, leviter convexi, striis incrementi curvatis 

 sculp ti ; spira ad apicem obtusa ; sutura leviter obliqua, dis- 

 tincta; apertura inverse subauriformis, longit. totius -f^ ad- 

 aequans ; labrum tenuissimum, in medio prominens, curvatum ; 

 columella subtortuosa, albida, leviter et tenuiter reflexa, callo 

 tenui labro juncta. 



Longit. 14 millim., diam. 5^ ; apertura 5 longa, 2| lata. 



Hah. Mamboia, at an elevation of 4000 to 5000 feet. 



This is a more slender species than Hapalus Orateloupi, 

 Pfr., the type of the group, has a somewhat shorter body- 

 whorl, and a less distinct spiral curve on the columella. In 

 one of the specimens there are about half a dozen roundish 

 eggs, which are seen through the transparency of the shell, as 

 in many species of Stenogyra. 



Bulimus [Hapalus) disparilis. (PI. V. fig. 13.) 



Testa perforata, ovata, superne paulo acuminata, albida, vel cerea, 

 nitida ; anfract. 6, convexiusculi, sutura leviter obliqua sejuncti, 

 longitudinaliter argute striati, striis curvatis, interne plus minus 

 desinentibus, ultimus magnus, subventricosus ; apex subobtusus ; 

 apertura elongata, inverse auriformis, longit, totius ^ superans ; 

 labrum tenue, in medio prominens, curvatum, prope suturam 

 quasi incisum vel sinuatum ; columella leviter obliqua, expansa 

 et reflexa, vix coutorta. 



Lougit. 13 millim., diam. 6| ; apertura 6| longa, 3 lata. 



Hah. Mamboia, at 4000 to 5000 feet elevation [Last).
