from the Persian Gulf, fyc. If 



quatuor similibus ordinibus decorato, apud basin angulato-planato, 

 decurtato ; apertura parva, labro tenui, columella paullum exca- 

 vata, can ali brevi. 

 Long. 5, lat. 1 mm. 



Hob. Persian Gulf, off Henjam Island. 



A very narrow aciculate species, quite distinct from the 

 Bombay C. sykesii, Melv.*, with which, from the figure, it 

 might easily be confounded. That is a much broader shell in 

 proportion, and coarser in its substance and sculpture. 



Three examples only, the most perfect being selected for 

 the type. 



Cerithiopsis (Seila) ochrolivens, sp. n. (PI. II. fig. 18.) 



G testa attenuata, anguste cylindrica, solida ; anfractibus nd 12, 

 apicalibus?, omnino spiraliter carinatis, superms tribus, an- 

 f ractu ultimo quatuor carinulis, quorum duobus suturahbus utrinque 

 lividis, carina centrali ochraceo-tincta, ad basin curta, planata ; 

 apertura ovata, margine columellari calloso. 



Long. 7, lat. 2 mm. 



Bah. Karachi, 190G. 



A small Seila, conspicuous for its ochraceous and grey 

 colouring alternating spirally on the whorls, the spiral^ keels 

 on either 3 side of the sutures being livid, while that in the 

 centre is ochraceous. Upon the body-whorl the two inner of 

 the four spirals are of that hue, the outer being livid. Ihe 

 base is curtly flattened and deplanate, with the columella!- 

 margin very callous. . . 



The only example of this distinct form is imperfect, and 

 the nuclear details are therefore wanting. 



Cohtmbella {Seminella) salutaris, sp. n. (PI. II. fig. 19.) 



G testa breviter fusiformi, nitida, parva, laevi, alba, vel stramineo- 

 'zonata; anfractibus sex, apicali parvo, ceteris gradatulis, ad 

 suturas' multum impressis, leniter laevicostulatis, superne, infra 

 suturas, incrassatis, ultimo anfractu laevicostulato, vel, ut saepe, 

 costis evaniclis, ltevigato, ad basin spiraliter striato ; apertura 

 anguste flexuosa, labro intus denticulate, crassiusculo, columella 

 ad°medium recta, deinde curvata, canali brevi. 



LoDg. 2-75, lat. 1-20 mm. 



Bab. Bombay (Abercrombie and Townsend). 



This is another species carved out of the miscellaneous
