HAWAIIAN NESOPUPAE. 319 



with close and somewhat rough growth riblets, minutely per- 

 forate, scarcely shining, somewhat thin. Spire obtuse, shortly 

 subcylindrical but yet slightly conic-tapering. Whorls 5, con- 

 vex, regularly increasing, suture impressed; the last shortly 

 ovate, swollen, somewhat saccate, hardly ascending in front, 

 not laterally compressed, rotund about the umbilicus. Aper- 

 ture slightly oblique, not sinuate, truncate-subcircular, hardly 

 effuse, furnished with tooth-like lamella?, as follows : two parie- 

 tal, one of which, the angular, is small tubercle-like, and the 

 second, parietal, median or nearly median, is elongate, more 

 deeply seated, ending abruptly. An acute, small columellar ; 

 and 2 short, nearly equal palatals, slightly elongate, parallel. 

 Peristome narrowly expanded and thickened on all sides, 

 slightly more dilated at the columella, livid, with quite dis- 

 tant margins. Length 2, diam. 1.33, apert. 0.75 mm. ' ' (Ancey ) .

 June 1904, p. 124, pi. 7, f. 17. 



The type specimen measures, length 2.15, diana. 1.4, apert. 

 (diag.) 0.86 mm. Interstices of costae granulose, the granules 

 arranged in rows, costee granulose ; apical whorls eroded, the 

 exact number could not be made out. 



The original specimens of this species were collected on 

 the Kupu side of Haupu. Specimens in the Bishop Museum 

 from near the original locality agree very closely with Ancey 's 

 type now in the Bishop Museum. One of these specimens, 

 carefully compared with the type, has 4y 2 whorls, the color is 

 argus-brown. The costae are lower, closer and more evenly 

 spaced than in typical P. newcombi; their edges only very 

 narrowly membranous. The embryonic whorls are distinctly 

 granulose when viewed under a strong lens; the angular 

 lamella is short, punctiform and seated close to the margin 

 of a rather thick parietal callus. The parietal lamella is 

 shorter than that of P. neivcombi, deeply seated and nearly 

 perpendicular to the parietal wall. The columellar lamella
