2 PRONESOPUPA. 



are obsolete, or only occur on the last half whorl, whilst 

 in others they regularly appear on each whorl; on the last 

 whorl about a dozen can be counted, either indistinct or very 

 prominent. A narrow, deep umbilicus is present. The colu- 

 mella is straight and reflected ; aperture discontinuous, almost 

 circular, with the outer lip reflected and expanded. In gen- 

 eral shape the specimens vary, some being more loosely coiled 

 than others which have a humped-up appearance. Height 2, 

 breadth 1.25 mm." (Iredale). 



Kermadec Group : Sunday Island. Living on tree trunks, 

 not moss-covered, and hiding in the crevices of bark in dry 

 weather (Iredale).

No species, in any way allied to this, has yet been recorded 

 from New Zealand, though I have seen very similar shells 

 with the mouth fully armed from Fiji. Nothing of this 

 nature has yet been found on Lord Howe Island, but the 

 species named Vertigo norfolcensis by Sykes, from Norfolk 

 Island, is referable to Nesopupa; it is, however, very much 

 larger and sinistral (Iredale). 



2. PRONESOPUPA SIMPLARIA (Pease). Not figured. 



Shell thin, obesely ovate, dextral, rimate, yellowish, longi- 

 tudinally delicately striate; whorls 3, rounded-convex, the 

 last flattened; suture deeply impressed; apex obtuse; aper- 

 ture nearly circular, toothless; peristome thin, margins sep- 

 arated ; columella spreading above, slightly expanded. Length 

 1.75, diam. 1 mm. (Pease). 



Marquesas.

Collector unrecorded. The species was not found by Gar- 

 rett, who catalogued the Marquesan shells in 1887. This 

 species could not be found in the Pease collection in the 

 Museum of Comparative Zoology, and is known by the above 

 description only.
