I would have been inclined to regard this race as merely a 

 subspecies of griqiialandica were it not that the exact number 

 of palatal folds is now considered of sectional importance in 

 the genus Ptychotrema, so should presumably be of at least 

 specific importance in the Pupillidae (Connolly). 



Nesopupa armata (Pease). Vol. 25, p. 327. 



' ' Last July Mrs. Cockerell visited the Island of Rarotonga, 

 and collected there a. Nesopupa which can by no means be separ- 

 ated from N. armata, described from Borabora, Society Islands. 

 The aperture is fully armed with the characteristic lamellae, 

 as figured by Pilsbry, only the infraparietal lamella is larger, 

 quite half as long as the parietal. The shell is about 2.3 mm. 

 long, with the characteristic sculpture, the upper whorls with 

 remote cuticular riblets. This is the first record of a Neso- 

 pupa from Rarotonga, since it appears that N. dentifera 

 (Pease), supposed to be from there, came from Aitutaki. 

 Our shell does not agree with Pilsbry 's figure of N. dentifera, 

 but it may be that the latter is a varietal form of armata. 

 Since the fauna of the Polynesian Islands is in general so 

 extremely different from that of the Hawaiian group, and 

 the sculpture of typical Nesopupa is so distinctive, it would 

 seem that N esopupilla and other groups should be regarded 

 as generically distinct" {T. D. A. Cockerell, Jour, of Conch. 

 XVII, 1924, p. 168). 



Nesopupa novopommerana Rensch. PL 21, fig. 5. 



Shell ovate, translucent, dark brown, the apex paler; per- 

 forate ; 5 whorls. Suture deep. Aperture rounded, the peris- 

 tome expanded, whitish, with 5 lamellae : angular lamella low 

 and short; parietal lamella long and higher; the palatal and 

 columellar lamellae as opposed to the basal lamella [lower- 

 palatal fold] smaller. The last whorl with a quite weak im-
