DESCRIPTION OF TWENTY-FIVE NEW SPECIES OF 
MARINE SHELLS FROM BOMBAY, COLLECTED BY 
MR. ALEXANDER ABERCROMBIE.* 
By James Cosmo MELVILL, M.A., F.L.S. 
Mornrx (OcINEBRA) BOMBAYANUS, sp. nov. (PI. 1, f. 1.) 
M. testa fusiformi, ochraceo-cinered, syvamata, apice acto, anfractibus 
septem vel oclo, angulato-cestatis, ultimo anfractu varicibus octo, in 
medio trinis angulorum ordinibus lrasversim succincto, apertura ovato- 
oblonga, pallescente, labro intus denticulato, canali brevi. 
Long. spec. typ. 31 mill. 
Lat. 16 mill. 
Hab. Bombay, common along the coast (A. Abercrombie, Herford, 
W. T. Blanford) (in Mus. Brit.). Ratnagiri (A. Abercrombie), 
Hyvidently a very abundant species, and in all probability extending 
some way both North and South of Bombay. The largest of the many 
specimens I have seen measures 35 millimetres longitudinally. It isa 
very uniform species in all stages of its growth, and would appear to 
have been confounded with M. luculentus (Reeve). Its nearest ally, 
however, would seem to be WV. cristatus (Brocchi) from the Mediter- 
ranean, from which, however, it is quite distinct. Some specimens are 
pale yellow, with faint brown transverse fascia. 
PLEUROTOMA (CLAVUS) PRAICLARA, sp. nov. (Pl. 1, f. 2.) 
P. testé pyramidato-fusiform, percrassd, pallidé ochraced, anfracti- 
bus septem vel octo, ad suturas valide impressis, longitudinaliter obliqué 
pluricostatis, transversim regulariter lirates, apertura oblonga simplice, 
labro exteriore in medio crassiusculo, canal brevissimd, margine colux 
mellart obliqui-planato. 
Long. 44 mill. 
Ibe 1G 
Hab. Bombay, up the coast (Abercrombie), 
A large, conspicuous species, of which all the specimens before us are 
somewhat worn : not sufficiently so, however, as to eftace the sculpture, 
From P. atkinsoni (Smith), crenularis (am.), flavidula (Lam.) it is 
quite distinct, beg more allied to the smaller sacra (Reeve) in my 
opinion, and a member of the sub-genus Cluvus rather than Drillia,
