314 HAWAIIAN NESOPUPAE. 



the Pfeiffer-Dohrn collection. The same author has stated 

 that Vertigo costulosa Pease, according to specimens from 

 Pease, is completely synonymous. Yet obviously Pease con- 

 fused two species in his description, as he says that the last 

 whorl is sometimes shortly bisulcate towards the lip. This is 

 not true of any form of N. newcombi, and probably indicates 

 that he had also a Nesopupilla.

 more often the angular lamella is less distinct. Length 1.5

Except for a slightly narrower form, as Boettger has already 

 pointed out, this variety differs in no way from some of the 

 various races of P. newcombi. In fact some of the narrower 

 forms mentioned above are not proportionately broader than 

 the measurements given by Boettger would indicate. The 

 name is preoccupied, but as its value is rather uncertain it 

 is not renamed at this time. 



A number of shells from different localities have the fol- 

 lowing measurements: 



Length 1.5, diam. 1.0 mm. 4% whorls; Kapua, Hawaii; 

 23375. 



Length 1.53, diam. 0.98 mm. 4% whorls; Puuwaawaa, 

 Hawaii; 39784. 



Length 1.65, diam. 1.05 mm. 4% whorls ; Lahaina, W. Maui ; 

 20967. 



Length 1.8, diam. 1.1 mm. 4% whorls; Waihee, W. Maui; 

 39012.
