A peculiarly select and highly sculptured Baphiella, unlike any 

 other form hitherto recorded from these seas. Some similitude with 

 D. {Taranis) MorcM, ^lalm,' from Northern European seas and Gulf of 

 Mexico, may be traced. Nearly all the specimens are imperfect, and 

 greater size is probably ultimately attained than is afforded in the 

 present material. 



Uaphnella (Pleorotomella) Alcestis, n.sp. PI. VIII, Fig. 23. 



D. testa ovato-fusiformi, delicatissima, parva, alba, vel pallide 

 straminea, anfractibus6-7, quorum apicales 3-4 pulcherrime decussato- 

 cancellati, ochracei, caeteris ad suturas bene impressis, ventricosis, 

 undique longitudinaliter crassicostatis, costis obliquis, spiraliter 

 tenuiliratis, liris paucis, ad juncturas costarum gemmuliferis, ultimo 

 anfractu apud basim producto, apertura fusoide, oblonga, labro tenui, 

 canali lato. Long. 6, lat. 1-5 mm. 



A delicate fusoid Daphnella, not perhaps quite adult, but the six 

 or eight examples that occurred were all much of the same size. It 

 seems almost exactly intermediate, as regards texture, between 

 B. Lxicasii and Clathurella amphihlestnim, Melv., from the same locality, 

 being in form like the former, from which it chiefly differs in the 

 presence of longitudinal ribs and different quality of spiral sculpture, 

 from the latter in general form, and, especially, more extended canal. 

 It is more than probable that CI. amphihlestrum, as well as Mangilia 

 ecphora, Melv., should be classed among the Baphiellce as of the 

 subgenus PleurotomeUa. Verrill. The eight allied species as yet 

 differentiated from the Persian Gulf region might be placed thus : —
