NILS HJ. ODHNER, MOLLUSCA. 
C. (Conidea) discors Gmrrin. 45 miles W. S. W., 60 feet (*%/r), 1 sp., 1. 20.4 
mm. This species has a shorter spire and a longer aperture than the preceding one. 
At the aperture the last whorl is strongly ascending. It occurs from East Africa 
to the Philippines and New Guinea (Tryon 1883, ScuEPMAN 1911). 
C. (Mitrella) moleculina Ductos (Pl. 2, figs. 48, 49). Shell ovate, pyramidal, 
with pointed apex and somewhat convex whorls, separated by shallow sutures well- 
defined below, smooth, except for faint lines of growth and some spiral lirations 
on the canal. Aperture about half the shell, outer lip crenelated within, and colu- 
mella with 3 small tubercles. Colour whitish with a fine net-work of brown and a 
subsutural interrupted line of brown, with a white dot above each streak and larger 
ones alternating with the streaks; a similar marking of reversed position and alter- 
nating with the upper one is usually present above the periphery and the suture 
on the upper whorls; both series connected by square brown dots with produced and 
connected corners, with or without a series of brown meshes between the dots; at 
the base of the last whorl a series of small brown dots. Locality: 42 miles W. S. 
W., 66 feet (''/7), 1 sp., h. 7 mm; wh. 8; 45 miles W. S. W., 66 feet (*"/r), 1 sp., 
h. 8 mm. 
A rose variety (fig. 49) with only the subsutural series of markings and a 
single row of brown dots on the base of the last whorl occurred at 42 miles W. 8. 
W., 66 feet (*'/7), 2 sps, max. h. 7.2, br. 3.2, aperture height 3.4 mm. 
The species moleculina is well defined by its subsutural] series of brown streaks, 
running along the whorls, and the white dots combined with them; it is easily 
distinguished from the seemingly nearly allied C. lineolata Prasr by its narrow and 
pointed, not broadly obtuse, spire, and the mentioned characteristics of its coloura- 
tion. The broken spiral line (also occurring in C. galaxias Reeve, Conch. Icon 11, 
1859, fig. 220) is single in the typical C. moleculina Ducios which has, further, 
4—5 columellar folds (cfr. Kope_r 1897, Die Columbelliden, Martini & CurEemnitz, 
Conch. Cab., p. 315, Taf. 40, fig. 7, and Hervirr, R. P. J., Le genre Columbella 
dans Varchipel de la Nouvelle-Calédonie, Journal de Conch., Vol. XLVII, No. 4, p. 
330, 1899). To the present form evidently belongs C. moleculina of HrpiEy (1901) 
from Katow and Port Moresby, N. Guinea. 
FAM. CYPRAEIDAE. 
Cypraea cribraria Linnt. 45 miles W. 8S. W., 80 feet (°*/s), 1 sp., 1. 24mm, 
br. 14, h. 11.5 mm; only 14 feeble teeth on the inner wall of the aperture and 15 
feeble teeth on the outer. A typical specimen of about the same size (I. 25.5 mm, 
br. 14.5, h. 11.65 mm) has 21 teeth on the inner and 21 on the outer wall. Further, 
the present specimen differs from the type in having a brown primary colour and 
somewhat larger spots. It is similar to fig. 161, Pl. 311 (var. esontropia REEVE, not 
Ducios) in Sowrersy, Thesaurus Conchyliorum, Vol. 4. — The species ranges from 
the Maldives and Ceylon to Mauritius and Funafuti, New Caledonia and New Ireland 
(E. A. Smrrx 1903, Hepiry 1899, Scoerpman 1909, TRyoN 1885).
