Show 454 LT.-COL. H. H. GODWIN-AUSTEN ON THE LAND- [May 21, Shell dextral, depressedly turbinate; openly umbilicated, 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 ; spire low; apex blunt; suture well marked ; whorls 4^, convex; aperture arcuately circular, subvertical, sinuate on outer margin, somewhat angular below at the peripheral ribs; peristome double-continuous. Fig. D. Cyathopoma natalicium. X12. 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, G.-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)= roepstorffiana, Nevill MS., from Katchall (de R.). This species in Mr. de Koepstorff's collection bears the name of D. carneola, Stol. == battimalyensis, Nevill. In the amended' Handlist ' I find the title roepstorffiana entered and the typical locality Katchall, with 3 specimens from Camorta and 20 from Batte Malve, collected by F. Stoliczka. It is somewhat similar to D. carneola from Moulmein, but it is more elongate and the costulation far closer and finer. 2. DIPLOMMATINA NICOBARICA, var. BATTEMALVENSIS, n. sp., Nevill M S . (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 nicobarica. Size: maj. diam. 1*3 ; alt. axis 3*0; body-whorl 0*9 mm, |
