416 MESSRS. MELVILL AND STANDEN ON [June 18, 



Engina epidkomidea Melv. 



I. Bombay (Abercrombie). The varices of this curious species 

 are peculiar, as also its elongate form, and very possibly it may 

 ultimately be relegated to a new genus. 



Engina zea Melv. 



P.G. A few specimens, dredged at 3^ fathoms near Linjah in 

 live condition, exhibit this most beautiful species more fully in 

 detail than ever before, it being chiefly known from beach specimens 

 gathered at Bombay and elsewhere. The nodules are light yellow- 

 ochre, interstices clouded with brownish-black, the white peri- 

 pherial band on the body-whorl is very distinct ; outer lip thick- 

 ened, 5-6-toothed within ; lip and columellar area pale lilac, clouded 

 with brownish-black round the region of the latter. 



M.C. Found at low tide amongst muddy rocks. 



1." Karachi. Bombay (Abercrombie and W. T. Blanford in 

 Mus. Brit.). Near Panjim and Goa (Lt.-Col. H. I). Olivier). 



We have also seen it from Aden (E. R. Shopland) and Ceylon. 



Engina (Pusiostoma) mendicaeia L. 

 P.G. Linjah, 3| fathoms, with E. zea. 

 M.C. Charbar, rocks at low tide. 



Nassaeia nivea Gmel. (Hindsia Gray). 



P.G. Gulf of Oman, Malcolm Inlet, 24 fathoms. Also in 

 the Gulf proper, Henjam Island, 15 fathoms. 

 M.C. Ormara, dead. 

 I. Karachi. 



Nassaeia sutuealis A. Ad. (=recurva Sowb.). 



P.G. Henjam Island. Gulf of Oman, Maskat. 



M.C. An uncommon species found, locally, along the shores of 

 Baluchistan, usually in crevices of rocks and in coral- sand. 7-15 

 fathoms. 



I. Bombay (Abercrombie). Locally abundant. 



Phos gladtsi^;, sp. n. (Plate XXIII. fig. 15.) 

 P. testa fusiformi, delicata, albida ; anfractibtis 8-9, quorum api- 

 cales 4—5 vitrei, albescentes, perlaives, turriti, infra medium 

 spiraliter acute bicarinati, in uno specimine simplices, ceteris 

 apud suturas impressis, longitudinaliter irregidariter costatis, bi- 

 vel trivaricosis, spiraliter arctissime rugoso-liratis, interstitiis 

 alveolatis; apertura ovata, labro paullum effuso, crassiusculo ; 

 canali brevi, lato ; columella versus basim quasi, uniplicata. 

 Long. 18, lat. 8*50 mm., sp. maj. 



Hob. Gulf of Oman, lat. 23° 44' N., long. 57° 59' E. ; 37 fathoms, 

 sand and mud. 



Only a very few examples of a delicate and pure white Phos, 

 apparently very nearly full-grown, though small, possessing in its 

 irregular longitudinal varices and general character of spiral 

 wrinkled liration some supei'ficial resemblance to P. roseatus Hinds.
