42 NILS HJ. ODHNER, MOLLUSCA. 
one still smaller notch, the largest incisions corresponding to the coarsest purple- 
stained costae. On the inside the colour shines through. — PILsBRY does not include 
this species in his Manual of Conchology, Vol. 12, 1890. REEVE records it from the 
Philippines, and HEDLEY (1910) from Queensland. 
Emarginula galericulata A. Apvams (Pl. 1, figs. 33—35). 45 miles W. S. W., 
66 feet ('”/+), I sp. with animal, 1. 3.6, h. 2 mm. The specimen has a greenish 
colour and has an apex highly bent posteriorly and a sculpture consisting of dense, 
radiating, finely nodulous ribs and interjacent elevated concentric lines in the inter- 
stices. The frontal rib is composed of a series of noduli, separated by pits; the 
distances between the noduli is > the breadth of the rib. The figure given by 
SOWERBY in 'Thes. Conchyliorum 3, pl. 246, fig. 24, shows only indifferently the shape 
and sculpture, for which reason I give a photograph of the present specimen in which 
these characteristics are more clearly shown. The species is only known from the 
Philippines. 
Emarginella clupeus ADAMS. 45 miles W. S. W., 48 feet, 1 sp. (/1), 1. 35 mm 
(animal), 24 mm (shell), and 1 sp. (""/1), 1. 15.5 mm (shell); 66 feet ("”/7), 1 sp, I. 12 mm 
(shell). 'The colour was either light rose (sp. 3) or white (sp. 2), and in the former the 
shell was uncovered on a larger area than in the latter. — In comparison with the 
specimen dredged by the Siboga expedition (cf. ScHEPMAN 1908) the present forms 
have denser sculpture, such as is described by PIiLsBRY (Manual of Conch., Vol. XII, 
p- 265, pl. 28, fig. 7). SCHEPMAN has shown that £. clupeus belongs to the section 
Hmarginella created by PIiLsBRY for HE. cuvieri (AUDOIN) ISSEL in consideration of its 
soft parts, which are »so voluminous as to be far larger than the shell». CooKkKE (1885) 
is of the opinion that £. planulata ADAMS from Singapore and HK. clupeus from the 
Philippines are identical with £. cuvtieri, and this is scarely to be doubted, as the 
latter has been shown to belong to the same section. A comparison of the present 
specimens with the figure of £. cuvieri given by SAVIGNY (Descr. de I'Egypte, Hist. 
Nat. 2, Tome IX, Pt. Gastéropodes, Pl. 3, fig. 2; Coquilles, Pl. 1, fig. 9) has shown 
only some slight differences in the sculpture and the place of the apex; the latter 
is situated more towards the front (subeentrally) in the present ones, and at the 
posterior third in that of SAviGNY. The furrow on the front slope is shorter in the 
present forms than the distance from apex to posterior margin, while in SAVIGNY's 
specimen it is longer, but these proportions are certainly subject to variation, for in 
the Siboga specimen the furrow is longer than the named distance. — The dimen- 
sions of the largest specimens are: shell: 1. 24, br. 16.3, h. at the middle 5.5 mm; 
animal: 1. 35, br. 28, h. 10 mm. — ScHEPMAN's I. sibogae is probably only a variety of 
this species; it has 12 epipodial filaments on each side, while the present one has 
more than 20; but this difference is probably due to the different sizes of the 
respective specimens. In SAVIGNY's specimen there are 38 ribs on the shell and 15 
epipodial filaments on each side of the animal. 
Scutus unguis LINNÉ. 42 miles W. S. W., 42 feet ("”/1), 1 sp., 1. 30 (shell), 36 
mm (animal); 70 feet (""”?!/s), 6 sps, max. 1. 27 mm (shell); 45 miles W. S. W., 66
