KUNGL. SV. VET. AKADEMIENS HANDLINGAR. BAND 52. N:0 16. 53 
CC: lutea GrRonovius. 45 miles W. S. W., 54 feet ("/1), 1 sp., 1. 16.5 mm. It 
belongs to var. f of REEvE (fig. 110 c, Conch. Icon. IIT) with 2 whitish bands. As to 
the colour of the animal was noted on the label: »Soft parts pretty light reddish 
tinted>. REEVE does not state any locality for the species. TRYON (Man. of Conch., 
Vol. 7, 1885) gives it as occurring in N. Caledonia and Australia; SCHEPMAN (1909) 
records it from the Moluccas, HEDLEY (1910, 1916) from Queensland and W. Australia. 
C. subviridis REzrvE. 42 miles W. S. W., 42—60 feet ("/1), 2 sps, max. 1. 30 
mm; 48 miles W. S. W., 78 feet ("”/7), I sp., I. 30 mm. The shape and the colour 
agrees with those exhibited by figure 48 of REEvE (Conch. Icon. 3, 1845). — Distri- 
bution: Cambridge Gulf (HEDLEY 1889), Queensland (HEDLEY 1910), New Caledonia 
(TRYON 1885), W. Australia (HEDLEY 1916). 
Trivia grando GASsKOoIn (Pl. 2, fig. 50, 51; text fig. 11). 42 miles W. S. W., 
66 feet (''/+), I sp., I. 8.5 mm. The specimen corresponds with the description and 
figures given by ROBERTS (TRYON, Manual of Conch., Vol. VII, p. 200, pl. 21, figs. 
86, 87), in the respect that the ribs are extremely fine and the spire is prominent, 
i. e. visible and feebly papilliform, projecting under the ribs. 'The shell is rose at 
both ends. The shape of the aperture seems to agree most nearly with the figures, 
as it is uniformly broad throughout and strongly flexuous (concave) only above at 
the spire, straight below (in contrast to 7. australis LAMARCK, where it is flexuous 
below in the same degree as above). The interstices between the ribs are smooth 
above, on the under side feebly granulose. The dorsal furrow lies somewhat to the 
left and is curved to the left. — As typical specimens are not at my disposal and 
the determination is thus somewhat uncertain, I give a photograph of the specimen 
for identification. Distribution: Manila (TRYON 1885), Queensland (HEDLEY 1910). 
TT. Oryza LAMARCK (Bl 2, figs. 52; ö3,, text fig. 12). 45 miles W. S. W., 66 
feet ("”/+) 3 sps, max. 1. 6.5 mm. The difference between this species and the pre- 
ceding one is shown clearly from the figures given here compared with those of the 
former. The dorsal furrow in the present specimen is rather short (< half the shell). 
The distance of the under margin from the basal (anterior) end of the furrow is equal 
to the corresponding apical (posterior) distance and equal to about '/2—?/s of the 
length of the furrow; the whole surface up to the furrow is rugous in the interstices 
of the ribs and the colour is pure white. — Distribution: Red Sea (TRYON 1885), 
Mauritius (V. MARTENS 1880), S. Africa (BARTsCH 1915), Moluccas (SCHEPMAN 1909), 
Victoria (PRITCHARD & GATLIFF 1899), Polynesia (HEDLEY 1899); Sandwich Isl. (TRYON). 
T. bipunctata n. sp. (Pl. 2, figs. 54, 55; text fig. 10). Shell of the same 
shape as 7T. oryza, only somewhat narrower; colour light reddish, somewhat deeper 
towards the ends and round the base; on the inner (left) side of the dorsal furrow 
2 reddish brown dots placed one behind the other. The dorsal furrow long (> '/2 
the shell); the distance from its anterior (basal) end to the shell end is '/2—?/s3 of 
the posterior upper corresponding distance and about !/s—'/1 of the length of the 
furrow. HNculpture consisting of strong radiating ribs with the interstices on the
