ranean, with which they have been compared. — The distribution comprises the 
whole tropical zone of the world (TRYON 1881, Man. of Conch., Vol. III, p. 11). A 
discussion of its nomenclature is given by HEDLEY, 1915. 
FAM. TURBINELLIDAE. 
Tudicla inermis SowErBYy. 42 miles W. S. W., 42 feet (""/+), I sp., I. 31 mm; 
45 miles W. S. W., 66 feet ("”/1r), 1 sp., I. 35 mm. Both specimens agree with the 
figures given by TRYON (Man. of Conch., Vol. III, 1881, pl. 58, fig. 410), where there 
are to be observed 3 folds on the columella; further, they have longitudinal folds 
or »knobs (about 8 on the last whorl) of a yellowish brown colour. The species is 
recorded from Singapore (with doubt by TRYON) and from W. Australia (HEDLEY 
1916). Both the present specimens were dead and inhabitated by Pagurids. 
FAM. FASCIOLARIIDAFE. 
Latirus niger n. sp. (Pl. 2, fig. 46). Shell turreted, of a dark brown colour, 
with a deep-violet aperture; canal produced (more than half the aperture in length). 
Sculpture: about 8 very broad and slightly elevated longitudinal swellings, erossed 
by coarse spiral cords (4 on the penultimate whorl); the second one below the suture 
feebler than the rest; a much fainter interjacent thread in each interstice; about 15 
cords on the last whorl, to the base of the canal, and some additional ones on its 
back. The interstices densely strigated longitudinally. Canal half-elosed. Columella 
with 3 plications. Outer lip inwardly with 7 distant riblets and beneath them 3 
narrower ones. Whorls 8, height 15, br. 5.3, aperture 1. 4.5 mm without, and 7 mm 
with the canal. Locality: 45 miles W. S. W., 70 feet ('/s), 1 sp. 
FAM. BUCCINIDAE. 
Phos textilis A. Apams (Pl. 2, fig. 47). 45 miles W. S. W., 48 feet ("/17); I sp., 
h. 17 mm. The species is considered by TRYON (Man. of Conch., Vol. III, 1881, 
p- 216) to be identical with Ph. senticosus LINNÉ, but form, size, and sculpture, are 
very different. The present specimen agrees in these respects most closely with 
figures 48 and 49 in SOWERBY's "Thesaurus Conch. 3, pl. 222, inasmuch as the whorls 
are inconspicuously convex, and the spiral sculpture consists of alternately stronger 
and feebler lirations; between an overlying feebler and an underlying stronger there 
appears a very faint thread, so that »every third one is prominent», as SOWERBY 
describes the characteristic sculpture; further there exist fine longitudinal striae 
between the lirae. On the last whorl there are 9 longitudinal ribs or folds. The 
colour is quite white with a feeble trace of a subsutural series of dots. The mouth 
is white inwardly. Whorls about 9. As SowERrRBY's figure is very indistinct, the 
species is photographically reproduceed here. Tt differs from Ph. senticosus in having 
= 
denser and narrower lirae (about 7 in contrast to Ph. senticosus which has 4—5
