56 PEOCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



^«J.— Persian Gulf, Gulf of Oman, lat. 24° 58' K., long. 56° 54' E., 

 156 fathoms. 



Judging from the figures of E. simplex (Orb.)^ from Jamaica, and 

 E. laxa, Wats., from Raines Island, Cape York, 155 fathoms 

 ("Challenger " Expedition), some affinity exists between them and this 

 species. E. simplex is also very finely spirally striate, E. laxa is 

 "spirally microscopically scratched."^ E. Philippiana, Dkr., from 

 Japan, is also rather similar in form, but this is a smooth and shining 

 species. Gedrosia is the ancient name of a maritime province of 

 Southern Persia. 



Etjlimella. ventjsta, n.sp. PL V, Fig. 15. 



E. testa aciculata, pergracili, alba, nitidissima, solidula, anfractibus 

 14, quorum apicales duo heterostrophi, vitrei, caeteris apud suturas 

 impressis, infra medium tiimide subangulatis, semipellucidis,perl8evibus, 

 nitidis, apertura quadratula, labro simplici, columella recta. Long. 7, 

 lat. l'25mm. (sp. maj.). 



^rt^.— Arabian Sea, lat. 18° 58' J^ , long. 71° 45' E., 40 fathoms. 



An extremely graceful shining white species, being a typical 

 EuUmeUa, whose whorls, impressed at the sutures, are slightly 

 pagodiform, each being tumid and bluntly angled below, just above 

 the sutures, and pinched in at the upper portion. This is the fourth 

 species of the genus now described from these seas. A smaller and 

 imperfect example of what is probably the same species also occurred 

 in the pi'olific dredging in the Gulf of Oman at 156 fathoms. 



Eenella xanthacme,^ n.sp. PL V, Eig. 16. 



F. testa imperforata, attenuato-fusiformi, alba, solidula, anfractibus 

 12, quorum apicales quatuor fulvi, apice ipso Isevi, dein huic proximis 

 obscure longitudinaliter striatis, cseteris 8, multum apud suturas 

 impressis, ventricosis, undique crasse reticulatis, ad juncturas lirarum 

 costarumque gemmulatis, interstitiis fere quadratis, ultimo anfractu 

 numero costarum longitudinalium circa 15, lirarum 6, infra peripheriam 

 usque ad basin 5 lirato, apertura rotundo-ovata, labro tenui. Long. 7, 

 lat. 2 mm. 



^«3.— Persian Gulf, Gulf of Oman, lat. 24° 58' N., long. 56° 54' E., 

 156 fathoms. 



An interesting Eenella, the fulvous apical whorls being very 

 conspicuous without the aid of a lens. The network, uniformly 

 ornamenting the somewhat ventricose whorls, is coarse for the size of 

 the shell, the interstices being almost square and somewhat large. 



Ancistrosyeinx oeientis, n.sp. PL V, Fig. 3. 



A. testa eleganterfusiformi, parum nitida, pallide brunnea, delicata, 

 tenui, anfractibus 8, quorum apicales duo parvi, globulares, vitrei, 

 caeteris Isevibus, ad medium acutangulatis, carina peripherali centraliter
