180 G-. & H. Nevill — New . Species of Marine Mollusea. [August, 



of domesticated races to re-assume this striped character, from the brilliantly- 

 striped foetus of the Asiatic and American tapirs, from the shoulder and 

 leg-stripes of many horses aud especially from the colouration of the Zebra, — 

 it might with confidence be inferred that the numerous porcine, tapirine, and 

 equine animals that had existed during the deposition of the older tertiary 

 strata were conspicuously striped creatures. 



3. — Descriptions of new species of Marine Mollusea from the Indian 

 Ocean. — By Gr. and H. Nevill.

Hingicula aooreviata. 



Regularly striated throughout ; whorls 3£, spire peculiarly short ; 

 outer lip crenulated as in JR. Charon, H., without any tubercle ; columella 

 with a broadly reflected, rugose callosity, with two teeth, parietal tooth 

 large. 



Long. 3, diam. 2£ mil. Ceylon. 



Drillia lucida. 



Smooth and glistening ; white, irregularly marbled with pale brown ; 

 apex somewhat mamillate and sinistral ; whorls 8i, divided with a deep 

 groove below the suture, longitudinally, distantly ribbed, last whorl only 

 transversely striated at its base ; columella smooth, sinus deep. Closely 

 allied to Hind's Clavatula quisqualis. 



Long. 8, diam. 3 mil. Persia, Andamans, Puri. 



Mangelia fttlvocincta. 



Attenuately fusiform ; whorls 9, longitudinally varicosely ribbed, minute-

 suture ; the lower portions of the last whorl, the outer lip and aperture are 

 brown, as is also the columella ; sinus obsolete, canal- very short and trun- 

 cate. 



Long. 8, diam. 3 mil. Bombay, Ceylon, Puri.

 culations on the outer lip, sharp transverse distant striae throughout, only 

 three on each whorl ; leaden brown colour, stained a darker shade on the 

 outer lip and on the columella.
