new Gastropoda from the Persian Gulf, &c. 313 
It is a remarkably smooth and shining shell, and the pome- 
eranate-pink colour (like the fruit of Punica granatum, L.) 
seems characteristic and quite peculiar.

D. testa parva, fusiformi, pallide rufa, solidula; anfractibus 8, 
quorum 2 apicales leves, vitrei, cxteris magnopere supra 
medium anfractum tumescentibus et spiraliter noduliferis, 
nodulis paucis, gemmatis, dein, anfractus apud supernos, torna-

pulchre et minute gemmatis; apertura quadrato-ovata, labro 
tenui, sinu lato, haud profundo, canali brevi. 
Long. 8, lat. 2°50 mm. 
Hab. Persian Gulf, Bahrein Islands, 6 fathoms, coral- 
sand. 
A small highly-coloured species, with conspicuous, spiral, 
swollen, nodulous angle just above the centre of the whorls. 
We cannot connect it nearly with any other species, 
Drillia audax, sp.n. (PI. XXIII. fig. 1.) 
D.testa oblongo-fusiformi, solida, parva, albo-straminea; anfractibus 
septem, quorum tribus nitidissimis, hyalinis, leevibus, apicalibus, 
ceteris trivis, antepenultimo quaternis, ultimo circa viginti 
spiralium lirarum ordinibus accinctis, ad anfractus supernos 
gemmulatis, supra suturas, etiam, lira spirali fortiori decorato, 
omnibus his liris stramineo-ochraceis ; apertura ovato-oblonga,

A little species of bold contour, and very distinct in both

rounding the whorls, which are not costulate. One spiral 
lira, acute and prominent, is especially noticeable at the base 
of each whorl, just above the sutures. . 
A good many examples occurred in the dredging, as above, 
in shell-sand.
