Hab. ad insulam Tablas dictam, Philippinarum. 

 Mr. Cuming has obtained only a single specimen of this species : 

 it is very different from all the others, its peritreme being continuous 

 nearly all round, the only interru})tion being about a seventh where 

 it is intersected by the last volution ; colour dull light brown, with a 

 dark brown band in front of the suture ; the greater part of the last 

 volution dark brown, and having a light narrow band near the um- 

 bilicus in addition to the light band near the suture. 



Helix incompta. Hel. testa ovata, tenuiuscula, ohscura ; epider- 

 mide fused, haud nitente induta, oblique tenuiler lineis incrementi 

 striata ; anfractibus quinque subconvexis, ultimo majori ; suturd 

 distinctd, antice posticeque fused ; aperturd subrotundd, postic'h 

 subacuminatd ; peritremate tenuiter rejiexo, rotundato, antice sub- 

 truncato, albo ; columelld rectd, albd, antice subtruncatd. 

 Long. M; lat. 0-66 poll. 



Hab. ad insulam Tablas dictam, Philippinarum. 

 Nearly resembling the last in shape and in its dull surface, but 

 differs in having no umbilicus, and in its peritreme not being nearly 

 so continuous. The last volution has its suture brown, a brown 

 band in the middle and another round the columella. A single spe- 

 cimen only was found. 



Helix stabilis. Hel. testa ovoidea, solidiuscula, Icevis, nitidiuscu- 

 la, alba ; anfractibus senis, paululum convexis, antice castaneis, 

 nigro-fasciatis, oblique lineis incrementi striatis ; aperturd obli- 

 qud, subovatd, intiis albd, peristomate albo, incrassato, rotundato, 

 antice subeffuso ; columelld albd, inconspicud, labio columellari 

 paululum expanso. 

 Long. 1-35; lat. 08 poll. 



A species which in general appearance bears some resemblance to 

 Bulinus ovoideus of Brug. and De F., tab. 112. f. 5, 6. (the same as 

 B. Luzonicus, * Conch. Illustr.' Bulinus, f. 53.) ; this species, however, 

 increases more rapidly toward the anterior part ; it has, moreover, 

 one more volution. The aperture is placed very obliquely, so that 

 the shell stands firmly when placed upon it. The dark burnt colour 

 of the anterior part of this shell is seen in every volution in the 

 form of a spiral postsutural band. It has a thick light- coloured epi- 

 dermis, of which some traces have not been entirely effaced. — G.B.S.
