GREENLAND. 
Northern shore of Baal’s River, near Nepiset Sound (Moller; Morch). 
GEOLOGICAL DISTRIBUTION: Unknown. 
Ecotocy: Artificial tank in Greenland (Moller). 
Remarks: Pingelu differs from vahlit in its smaller size, more 
cylindrical shell, shorter and blunter spire and in its more feebly de- 
veloped inner lip; the aperture is generally more ovate and the um- 
bilical chink is larger. The variety seems to occupy about the same 
range as vahli and frequently occurs associated with it. Its short 
stumpy spire, which is almost always decollated, will invariably dis- 
tinguish it from valu. Its dark color is also a distinguishing feature. 
It resembles some forms of arctica Lea from which it may be 
known by the absence of the columellar plait and also by its thinner 
shell. The specimens referred to arctica by Whiteaves (Nautilus 
XIX, p. 3), upon examination seem to be referable rather to pingelit. 
They certainly do not agree with the shells brought from Hudson Bay 
by Dexter, and they do agree with the specimens referred to pingelit, 
as well as with the published descriptions and figures. 
Galba neopalustris, Sp. nov. Plate XXXIX, figure 28. 
SHELL: Small, thin, ovate-conic; color reddish brown; sculpture 
of fine growth lines crossed by distinct spiral lines; last whorl some- 
what malleated and encircled by a number of heavy, equidistant spiral 
ridges ; whorls 5-6 (the earlier ones usually eroded) rounded, roundly 
shouldered, the body whorl quite obese; the upper part of the whorls 
is somewhat flatly sloping; spire acutely conic, usually eroded to the 
third whorl, longer than the aperture; sutures well impressed; aper- 
ture roundly ovate; peristome thin, slightly thickened within; inner lip 
very narrow, the upper part, together with the parietal callus folded 
tightly over the parietal wall; there is a very minute umbilical chink; 
axis twisted.
