76 NILS HJ. ODHNFR, MOLLUSCA. 
a double peristome caused by a furrow which separates the lip callus from the edge. 
Canals two in number, very short, the right one bounded only above by a feeble 
tongue, the left one situated a little beneath the middle of the aperture and bounded 
both above and below by thickenings of the peristome. 
An umbilical keel emanating from the left canal and sur- 
rounding the rather narrow umbilicus. Dimensions: height 
9, breadth 4, h. of aperture 2.7 mm; whorls 6. Locality: 
Colosseum (November 1912), 5 sps. 
Radula 3.1.3 (fig. 26), median tooth with 3 broadly 
rounded cusps, first lateral with one broad median cusp 
and one small dentiele on each side of it — by suitable 
position of the tooth a second minute denticle is visible on 
the inside —; second lateral with a strong cusp, a bifid 
denticle inside it and a simple smaller one on the outer Fig. 26. Radula of Pupinella 
side; third lateral with a bifid dentiele and a broad cusp Åenegeoefal tar Här vr 
but without exterior denticle.

FAM. RHYTIDIDAE. 
Rhytida sheridani BrazieEr. Atherton (Jan. 1913), 2 sps, max. d. 28 mm (colour 
dark brown); Malanda (Febr. 1913), 1 sp., d. 22 mm (colour yellowish brown); Cedar 
Creek (April 1913), 1 sh., d. 26 mm. — Queensland, with no definite locality, 3 shs, 
max. d. 35 mm. The whorls of this species are more rounded than in R. confusa 
PFEIFFER (cf. figs. 10—12, Taf. 6 in V. MOELLENDORFF, 1902, MARTINI & CHEMNITZ, 
Conch. Cab-.). 
R. strangei PFEiFrerR. Atherton (Jan. 1913), 1 sp., d. 19 mm; Malanda (Febr. 
1913), I sh., d. 15 mm; Cedar Creek (April 1913), many sps, max. d. 22 mm; Bel- 
lenden Ker (May 1913), I sp., d. 14.5 mm. ; 
R. capillacea FÉrussac. Colosseum (November 1912), 3 sps, max. d. 15 mm; 
Carrington (May 1913), 1 sp., d. 18 mm. This species, differing from RK. stranger 
only in the absence of spiral striae, is probably only a variety of the last-named form. 
FAM. NANINIDAE. 
Parmacochlea fischeri SmitH. Atherton (Jan. 1913), many sps, even with 
eggs, max. 1. (anim.) 31 mm; Yarrabah (May 1913), 1 sp., 1. 21 mm (animal), 10 mm 
(shell); Millaa-Millaa (July 1913), 1 sp., I. 14 mm (anim.), Bellenden Ker (May 
1913), 2 sps, max. 1. 16 mm (anim.). -— According to HEbDLEY, who has published 
a description of its anatomy and radula (1893), it is fairly common in N. Queensland 
Ninof,207,5.
