Hah. Persian Gulf [Col Pdhj). 



The graiuilalion of the third and fourth whorls is produced 

 by the longitudinal ribs and spiral lirations being very close 

 together, and the points of intersection being granulous. The 

 spiral lirse on the remaining whorls are slightly acutely pro- 

 minent on crossing the costfe. In two specimens a second 

 obsolete tootli within the labrum situated a little below the 

 other is traceable. The whitish bands are not very clearly 

 defined, but appear to blend gradually with the ground-colour 

 of the shell. 



Pleurotoma [DrilliaT) amcena. 



Testa fusiformis, dilute flavescens, circa medium anfractuum albo 

 zonata ; anfraci. 8, convexi, primi 2 laeves, ccetcri longitudinaliter 

 costati (in anfr. ultimo costis 18 infra medium desinentibus) 

 spiraliter lirati, liris supra costas nodulosis (in anfr. superioribus 

 5-6, in ultimo circiter 15, paucis ad basim enodatis) ; apertura 

 longit. totius f ada?quans ; canalis angustus, paululum elongatus. 



Long. 14 mill., diam. fore 5.

Two of the spiral lirations a little below the sutui*e are finer 

 than the others. The whorls are markedly convex and the 

 apical ones are large. 



Pleurotoma [Drillia?) auriformis. 



Testa fusiformis, paululum turrita, albida vel pallido lutescens ; 

 anfractus 9, primi duo Iseves, convexi, sequentes 2 medio cari- 

 nati, caeteri superne oblique planulati, medio leviter angulati, 

 deinde planiusculi, costis circiter 14 parum prominentibus (in anfr. 

 ultimo infra medium sensim evanescentibus) et liris spiralibus 6-7 

 (in anfr. ultimo circiter 20) quarum illae supra angiilum sitae 

 quam cseterse tenuiores sunt, cancellati ; apertura longit. totius 

 A adaequans ; labrum paululum pone marginem incrassatum, 

 superne sinu conspicuo, aliquanto profundo et dextrorsum pro- 

 ducto ornatum, intus dentibus obsoletis 2-3 munitum ; canalis 

 subelongatus, angustus ; columella liris transversis 3-4 baud 

 conspieuis omata.

The chief characteristic in this species is the peculiar 

 manner in which the rather large sinus is directed outwards
