DESCRIPTIONS OF SIXTY-EIGHT NEW SHELLS. 227 



Long. 8, lat. 3 mm. 



Hub. Gulf of Oman, lat. 24° 58' N., long. 56° 54' E., 156 fathoms. 



The two species D. amphitrites and D. wreidum occur together, but we 

 think it correct to separate them, though undoubtedly they are nearly allied. 

 The present species is the less angular, rather larger, and of a more roundly 

 cylindrical form. 



DAPHNELLA THYGATRICA » sp. n. (PI. D. fig. G.) 

 D. testa parva, fusiformi, tornata, albo-straminea,longitudinalliter pallide rufo- 

 tincta ; anfractibus 7, quorum fcrea apicales apice ipso lam mamilato, duobus 



pulchre sub lente decussatis, ceeteris spiraliter ad medium, ultimo ad periphe- 



riam duplo-carinatis, lirisque kevibus, fortiter succinctis, ultimo anfractu ad 



medium, inter carinas, recto ; apertura oblonga, labro tenui, sinu obscuro, 



margine columellari incrassato, albo, nitido, canali lato, paullum producto. 

 Long. 7, lat. 2'50 mm. 



Hob. Gulf of Oman, lat. 24° 58' N., long. 56° 54' E., 15G fathoms. 



A small Drillia in miniature, looked at superficially, but the decussate apical 

 whorls are Daphnelloid. It occurred somewhat commonly at the above station. 



DAPHNELLA THIA f , sp. n. (PI. D. fig. 8.) 

 D. testa delicatissima, subpellucida, attenuato-fusiformi, albida, nitida ; 



anfractibus octo, quorum 3£ apicales ochro-tincti, pulchre deeui-sati, ceteris 



tumidulis, liris arctis longitudinalibus spiralibusque decussatis, liris interdum 



pallidule stramineo-tinctis nitidulis ; apertura oblonga, labro tenui sinu lato 



baud profundo, canali brevi, lato, paullum producto. 

 Long. D^Ojlat. 3 mm. 



Hab. Persian Gulf, Sheikh Shuaib Island, 15 fathoms ; Gulf of Oman, lat. 

 24° 58' N.,long. 56° 54' E., 156 fathoms. 



Most delicate and beautifully closely encircled with decussating lira;, a faint, 

 straw-coloured or golden tinge being sometimes observable on them. Tho 

 specimens from the first locality mentioned are not so tumid on the body- 

 whorl ; we cannot, however, separate them, even varietally, from the typical 

 form from the Gulf of Oman. This differs from D. boholensis, Reeve, not 

 only in the fine decussations, but in the canal being more prolonged and 

 greater tumidity of whorls. 



DAPHNELLA BUCCINULUM%, sp. n. (PI. D. fig. 9.) 

 D. testa ovato-rotunda, bucciniformi, delicata, alba, interdum pallide ochraceo- 



suffusa ; anfractibus 7, quorum 3 apicales rufi vel straminei, tenuissime 



decussati, cseteris arete et delicate obliqui cancellatis, ad suturas impressis,. 



tumidis, inflatis, ultimo anfractu pyriformi ; apertura oblonga, labro tenui, 



sinu indistincto, margine columellari excavatulo. 

 Long. 7, lat. 3*75 mm.
