62 A Visit to Damma Island : 



the same kind of spire, a sharpish keel at the periphery, and 

 a smooth nucleus. 



4. Chloritis dammaensis. 



Testa depressa, suborbicularis, umbilicata, mediocriter tenuis, fusce- 

 sceus, haud nitida, liueis incrementi tenuibus striata, undique 

 miniito punctata ; anfractus 4, convexi, sutura profande sejunoti, 

 ultimus ad peripheriam acute rotundatus, antice breviter descen- 

 dens ; spira depressa, ad apicem obtusa ; apertura late lunata, 

 obliqua ; peristoma tenue, caeruleo-albidum, breviter expansum 

 et retiexum, marline columellari superne dilatato, reflexo. 



Diam. uiaj. 16 millitn., min. 14, alt. 10 ; apertura 7 alta, 5 lata. 



Chloritis Micholitzi, Mollendorff*, from Timor-Laut, is a 

 similarly depressed species, but otherwise different in form. 

 Its aperture is much more elongate and the body-whorl 

 descends more obliquely and is more regularly rounded and 

 not so shouldered as in the present form. The upperside of 

 C. ursina, PfeifTer, from the Admiralty Islands is peculiarly 

 like that of C. dammaensis, but the form of the aperture and 

 the sculpture are different. 



5. Cochlostyla (Corasia) tenimberica, Mollendorff. 



Cochlostyla (C'orasia) tenimberica, MolldfL Nachrichtsbl. deutsch. mal. 

 Geaell. 1892, p. 97, pi. i. fig. 2. 



A single specimen from Damma is a little larger than the 

 type, having a major diameter of 26j millim. On comparison 

 with an example from Timor-Laut, the columella appears a 

 little different, being less thickened, and the reflexed white 

 callus in the umbilical region is wanting. In other respects 

 the shells are so alike, that I have no doubt of their being 

 conspecific. 



6. Opeas TucJceri, Pfr. ? 



Hob. Sir Charles Hardy's Island, North Australia, &c. 



Dr. Mollendorffquotes O.gracih, Hutton, from Timor-Laut, 

 but that species is more acuminate or tapering than the speci- 

 mens from Damma. These are hardly so slender as the type 

 from Hardy's Island, but are very similar to other examples 

 of this species from Mabuiag, N. Australia. 



7. Leptopoma vitreum, Lesson, var. 



The three specimens from Damma appear to agree with var. 

 intermedia, Martens (Reise Ost-Asien, Zool. vol. ii. p. 144\
