The extremes seem distinct from E. tricarinata Ad. & Eve., but 

 the species is evidently, though rare, very widely distributed, and 

 intermediates may, in time, be found to occur. 



I. Lat. 18° 58' N., long. 71° 45' E. 40 fathoms.

It seems doubtful whether this species be rightly relegated to 

 this genus. From the descinption, it might be nearer allied to 

 Onoba. Unfortunately, the type having been accidently broken, 

 the question is not easily cleared up. 



AcLis CALOTROPis \ sp. n. (Plate XXII. fig. 3.) 

 A. testa minuta, attenuato-fusifoi'mi, gracili, pellucente, tenui, 

 nitida ; anfractibiis 10, quorum duo apicales mamillati, vitrei, 

 simplices, cceteris nitidis, Icevibus, spiraliter tornatis, obscure 

 liratis, apud medium conspicue acutimrinatis, idtimo anfractu 

 pauUulum producto, versus basim spiraliter lirato ; apertura 

 ovata; labro tenui, ad basim' angulato ; columella recta, producta. 

 Long. 3, lat. 1 mm. 



Eab. Gulf of Oman ; lat. 2^° 05' N., long. 57° 35' E. 205 

 fathoms. 



A very delicate species, vitreous, 10-whorled, delicately spirally 

 Urate ; the Hrae distant, few, and conspicuously once acutely keeled 

 at the centre of each whorl ; the last whorl is slightly prolonged ; 

 mouth ovate, lip thin ; columella produced, causing a slight angular 

 projection at the base of the lip. 



AcLis ENiLDA, sp. n, (Plate XXII. fig. 4.) 



A. testa pergracili, delicata, subvitrea ; anfractibus 12, quorum 

 apicales tres, Iceves, vitrei, cceteris ventricosis, apud suturas 

 multum impressis, nitidis, undique spi^'aliter arete et regulariter 

 liratis, Uris filosis, albidis, pellucentibus ; apertura rotunda ; 

 labro effuso, tenui ; columella fere recta. 



Long. 8, lat. 2 mm. 



Hab. Grulf of Oman, Maskat. 15 fathoms. 



A peculiarly refined and exquisite shell, allied in form to A. 

 loveniana A. Ad. from Japan, but abundantly distinct. It is not 

 unlike a small Turritella, being twelve-whorled, including three 

 apical smooth and vitreous, the remaining nine being ventricose, 

 much impressed at the sutures, uniformly closely spirally lirate, the 

 lirse threaded, subpellucid; mouth rounded, outer lip thin, effuse; 

 columella almost straight.
