TESTACELLA VAGANS, n. 8. = Daudebardia nove-zealandia, Trans. N.Z. Inst., 
xiv., p. 152 (not of Pfeiffer). 
Shell auriform, subspiral, depressed, imperforate; elongately oval, the 
sides nearly parallel, the anterior end rather broader than the posterior ; 
columellar margin callous; apex subspiral, posterior; pale horny, striated 
with growth-lines. Length of aperture 0-37; breadth 0°22. Teeth, 15-0-15. 
Animal (in spirit) above slate grey, gradually passing into yellowish 
white on the sides; sole yellowish white; the sides rather marbled with 
grey. 
Hab. Auckland (T. F. Cheeseman), and Waiuku (T. Kirk). 
The specimen described in the Trans. N.Z. Inst. for last year was with- 
out its shell and consequently I thought that it was Daudebardia nove- 
zealandia, the shell but not the animal of which species I know, but Mr. 
Cheeseman has sent me a specimen with the shell on, and it proves to be 
quite different. The shell is much like that of T. mangei, but the dentition 
appears to be different.

LEPTOPOMA PANNOSA, Sp. nov. 
Shell conical, subcarinated, umbilicated, brown, covered with a dark 
fuscous, ragged epidermis. Spire acutely conical; whorls six, rather 
flattened, the last convex below and rounded at the angle; apical whorls 
showing close oblique growth-lines; base flattish with close growth-lines 
crossed by delicate spiral strie; suture impressed: epidermis forming 
ragged oblique, rather distant plaits on the whorls, and at the periphery 
produced into triangular pointed processes: umbilicus narrow, open: aper- 
ture rather oblique, broadly ovate ; peristome thin, regularly arched, or 
slightly angulated at the periphery, slightly patulous, margins not meeting. 
Height 0:18, diameter 0-11 inch. 
Operculum thin, transparent, horny, yellow, subcircular, of five gradually 
enlarging whorls; nucleus subcentral. 
Animal like Cyclostomus; pale grey, the tentacles darker; rostrum 
whitish. Tentacles short, rather stout, pointed ; eyes large, at their outer 
bases. Dentition, 8-1-8. 
Hab. Greymouth, under very damp logs and earth (Mr. R. Helms). 
In shape this species is much like Hydrocena rubens, Q. & G. (Cyclo- 
stoma) from Mauritius, figured in Adams’ Genera of Mollusea, pl. 87, fig. 2, 
but the operculum is quite different. 
 LzProPowA cava, sp. nov. 
Shell conical, reddish brown with a thin spiral pale band below the 
periphery ; spire acutely conical ; whorls 64, rather flattened, the last con- 
vex below and rounded : epidermis smooth, forming numerous fine oblique
