Eglisia leptomita Melv. & Sykes. 



Turritella leptomita Melv. & Sykes, Proc. Mai. Soc. Lond. vol. ii.

P.Gr. Linjah, 3| fathoms. 



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

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

 intermediates mav, in time, be found to occur. 



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

1. Bombay (Abercrombie). 



It seems doubtful whether this species be rightly relegated to 

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

 Onoba. Unfortunately, the type having been accidently broken, 

 the question is not easily cleared up. 



Aclis calotkopis \ sp. n. (Plate XXII. fig. 3.) 

 A. testa minuta, attenuato-fusiformi, graciU, pellucente, tenui, 

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

 aimplices, cceteris nitidis, Icevibus, spiraliter tornatis, obscure 

 Jiratis, apud medium conspicue acuticarinatis, ultimo anfractu 

 paullidum producto, versus basim spiraliter lirato ; apertura 

 ovata; labro tenui, ad basim angidato; columella recta, producta. 

 Long. 3, lat. 1 mm. 



Hab. Gulf of Oman ; lat. 24° 05' N., long. 57° 35' E. 205 

 fathoms. 



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

 Urate ; the lira? 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 

 apical V.? tres i hives, vitrei, cceteris vcntricosis, apud suturas 

 multum impressis, nitidis, undique spiraliter arete et regidariter 

 lirnt'is, litis /ilosis, albidis, pellucentibus ; apertura rotunda; 

 labro effuso, tenui; columella fere recta. 



Long. 8, lat. 2 mm. 



Hab. Gulf 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 bring ventricose, 

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

 lira; threaded, subpellacid; mouth rounded, outer lip thin, effuse; 

 columella almost straight.
