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 Subulina 
subcarinifera . That species is imperforate, much more 
coarsely sculptured, and has a more distinctly truncate colu- 
mella. The apex in both forms is similarly introverted. 
Bulimus ( Buliminus ) subolivaceus. 
Buliminus olivaceus (Gibbons, MSS.), Taylor, Quart. Journ. Conch, 
vol. i. p. 253, pi. ii. fig. 5. 
Hab. 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. sub - 
olivaceus , the colour being decidedly pale olive. 
Bulimus ( Hapalus ) subvirescens . (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 T 5 3 ad- 
sequans ; labrum tenuissimum, in medio prominens, curvatum ; 
columella subtortuosa, albida, leviter et tenuiter reflexa, callo 
tenui labro juncta. 
Longit. 14 millim., diam. 5g ; apertura 5 longa, lata. 
Hab . Mamboia, at an elevation of 4000 to 5000 feet. 
This is a more slender species than Hapalus Grateloupi , 
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. (PL 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, inferne 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 contorta. 
Longit. 13 millim., diam. 6| ; apertura 6| longa, 3 lata. 
Hab . Mamboia, at 4000 to 5000 feet elevation (Last) .
