Shell dexti'al, depressedly turbinate; openly umbilicated, flat 

 below, angulate at the umbilicus ; sculpture smooth above, with 

 very fine regular transverse costulation on the last whorl, with 

 a strong lirate rib on the periphery ; colour pale ochraceous ;

Kg. D. 



Cyathoponm natalicium. X 12. 



Size : maj. diam. 2-25 ; alt. axis 1*2 mm. 



Operculum multispiral, elongate, with a deep central depression. 

 This appears, from the number of specimens in the tube, to be an 

 abundant species. It is a very pretty distinct form. 



Genus Diplommatina. 



1. DiPLOMMATiNA NicoBARicA, Gr.-A. Land and Freshwater 

 Moll. Ind. p. 185, pi. xlvi. figs. 7, 7 a (p. 444). 



This species is no. 13 of Mr. G. Nevill's Hand-list (p. 284)= 

 rnepstorffiana, Nevill MS., from Katchall {de R.). 



This species in Mr. de Eoepstorff's collection bears the name of 

 B. carneola, Stol. = battimalyensis, Nevill. In the amended ' Hand- 

 list ' I find the title roepstorffiana entered and the typical locality 

 Katchall, with 3 specimens from Camorta and 20 from Batte 

 Malve, collected by F. Stoliczlia. It is somewhat similar to D. 

 carneola from Moulmein, but it is more elongate and the costulation 

 far closer and finer. 



2. DiPLOMMATINA NICOBAEICA, ' Var. BATTEMALTENSIS, n. Sp., 



Nevill MS. (p. 444). 



I have discovered among some shells put up by Mr. G. Nevill 

 two specimens in a tube, labelled as above, from the island of 

 Batte Malve ; they agree in all characters with the last species, 

 but are much larger and more tumid, the antepenultimate whorl 

 being much larger than in nicoharica. 



Si;:e : maj. diam. 1*3 ; alt. axis 3'0 ; body-whorl 0*9 mm.
