FAM. PYRAMIDELLIDABE. 
Pyramidella (Lonchaeus) sulcata A. Apams. 45 miles W. S. W., 70 feet ('"/s), 
1 shell, h. 21.5 mm, very similar to P. teres A. ADAMs (figured by TRYON, Man. of 
Conch., Vol. VIII, 1886, pl. 72, fig. 82) and with a distinet median suleus on the 
last whorl. — Distribution: Red Sea, Mauritius, Australia, Philippines, Sandwich Isl. 
(TRYON 1886). 
FAM. EBULIMIDAE. 
Eulima martinii A. ADAMms. 42 miles W. S. W., 60—72 feet (?-'"/;), 2 dead 
shells, max. h. 31.5 mm; 45 miles W. S. W., 54 feet, 1 sp., h. 32 mm; 48 miles 
W. S. W., 78 feet (""/-), 1 shell, I. 19.5 mm. The specimens agree very well with 
the figures given by REEVE (Conch. Icon. 15, 1866, fig. 6) and TRYON (Man. of 
Conch., Vol. VIII, 1886, pl. 68, fig. 90); they have the strikingly pyramidal shape 
and the feeble angularity characteristic of the species. It is recorded from the China 
Sea and Singapore (TRYON), from the Persian Gulf (MELVILL & STANDEN 1901), 
Lombok and Japan (SCcHEPMAN 1909). 
Mucronalia eburnea DEsHAYESs (Pl. 2, fig. 45). On Ophiothrix sp. from Cape 
Jaubert, 45 miles W.S. W., 70 feet ('/e), I sp., h. 4 mm, with 6 whorls, and in entire 
agreement with the figure in DESsHAYES 1863 (Conch. Réunion) in the convex whorls. 
SCHEPMAN (1909) records this species from the Arafura Sea (Siboga Exp-.). 
M. variabilis ScHEPMAN (Pl. 2, fig. 45). Together with the preceding form on 
the same specimen of Ophiotrix from 45 miles W. S. W., 70 feet, I sp. h. 2 mm, 
wh. 3. This specimen is attached somewhat above the preceding one. As it carries 
a distinet operculum but no false mantle, and as its form is in entire agreement 
with M. variabilis figured and described by ScHEPMAN 1914, I do not hesitate in 
referring it to this species, though the mode of parasitism in the present specimen is 
different from that of the typical ones, which were found as ecto- and intestinal 
parasites on a Synapta from Zanzibar. Of the genus Mucronalia most species are 
found on Ophiurids or Echinids (cf. SCcHEPMAN 1909), but none of them correspond 
to the present form as much as does M. variabilis. The shell of the specimen before 
me, though young, shows the same configuration of the apex and the same con- 
vexity of the two sequent whorls, as well as a similar constriction beneath the suture 
of the body whorl, as ScHEPMAN describes. Further, the produced shape and the 
protracted median part of the outer lip are exactly the same in both forms. 
FAM. TRITONIDAFE. 
Cymatium australasiae PErry (= Triton olearium Auct., not LINNÉ). 45 miles 
WIS: W., TO feet ('/s), I 'sp., h. 20.5 mm; 66 feet (”/1), 1 sp., h:/13 mm. — Though 
small they show no differences from specimens of the same species from the Mediter-
