Long. 14*50, lat. 4 mm. 

 Hob. Mekran Coast. 



A very attenuate, finely aciculate species of sombre 

 colour, and rude irregular longitudinal plaiting. I agree 

 with Mr. Hinds and other authors that the genus is 

 difficult to sub-divide ; but this shell would probably be 

 termed an A ens, being allied to A. cinerea Bom. in form. 



{severus, grave, austere.) 



Terebra (Euryta) thyr^ea, sp. nov. (PI. 6, f. 13). 



T. testa gracili, nitida, fusiformi, albida, anfractibus octo r 

 quorum duobus apicalibus, pervitreis, Icevissimis, cczteris ventri- 

 cosis, apud suturas impressis, longitudinaliter indistincte 

 obliquicostatis, apud basim evanescentibus, undique spiraliter 

 irregulariter sulculosis, anfractibus supernis transversim 

 brunneo-vittatis supra suturas, in ultimo trivittato, viz.; infra, 

 juxta suturam, irregulariter squarroso-maculato, apud medium 

 laticincto, ad basim vitta continua irregulari dorsaliter con- 

 fluente, apertura recta, angusta, labro tenui, columella recta. 



Long. 12, lat. 4 mm. 



Hab. Karachi and Mekran Coast. 



This is a very elegant, chaste species, and. quite an 

 outlying form of the genus, being most allied to T. 

 (Euryta) Brazieri Angas, from Australia, and T. pulchella 

 A. Ad. It is almost an Olivella in shape, graceful, attenu- 

 ate, white with transverse interrupted brown banding 

 or spotting, eight-whorled, two being transparent, apical, 

 the remainder obscurely longitudinally obliquely ribbed, 

 and irregularly sulculose. Aperture straight, narrow, 

 outer lip simple, columella straight. Two specimens. 



(Ovpaio?, outside, outlying, from its characters when 

 compared to the majority of the genus.)
