Bay of Bengal and the Arabian Sea. 163 



In some respects this species resembles M. Beam, Fischer 

 and Bernardi, from the West Indies. It differs, however, in 

 form, the rostrum being longer, and the spiral lirae are more 

 numerous. 



9. Nassaria coromandelica. (PI. IV. fig. 3.) 



Testa breviter fusiformis, solida, albida ; anfractus 10, priini tres 

 (nucleus) lsevigati, convexi, caeteri convexiusculi, costis longitu- 

 dinalibus nuraerosis leviter arcuatis, lirisque spiralibus circiter 

 tres vol quatuor supra costas nodosis cancellati, inter liras striis 

 filiformibus cineti, ad suturam quasi canaliculati, ultimus con- 

 vexus, infra medium contractus ; apertura supra pyriformis, 

 inferne late canaliculata, salmoneo-rufo tincta ; labrum ad 

 marginem acutum, varice validissimo externo incrassatum, intus 

 liris 7-8 haud ad marginem attingentibus instructum ; columella 

 superne arcuata, callo tenui induta, transversim lirata ct tuber- 

 culata, lira suprema cseteris majori ; canalis latus, profundus, 

 obliquus, leviter recurvus. 



Longit. 35 millim., diam. 15 ; apertura cum canali 17 longa, 6g lata. 



Hah. Off Coromandel coast, lat. 14° 05' 55" N., long. 

 80° 25' 20" E., in 112-138 fathoms. 



The spiral lira? are alternately larger and smaller, the 

 former being nodulous on crossing the longitudinal costaa. 

 Of the lirae within the aperture, the third from the top is 

 rather more prominent than the rest. It differs from Nassaria 

 nivea (Gmelin) in its larger size, more open, less oblique, and 

 less recurved canal, the very strongly developed post-labral 

 varix, the colour within the aperture, different tuberculatum 

 on the columella, and fewer liraa within the outer lip. 



The Triton carduus of Reeve, which is united with N. nivea 

 by Tryon (Man. Conch, vol. iii. p. 221), has no relationship 

 whatever with that species. It undoubtedly belongs to the 

 Tritoniidas, and may be placed in the group Colubraria. Fine 

 examples in the Museum collection were received from 

 M. Robillard from the Mauritius. The type of T. carduus is 

 a half-grown shell, the adult form having a length of 

 22 millim. Reeve's figure (' Triton,' fig. 95) is twice the 

 length of the shell delineated. The reference to Gmelin 

 should be p. 3495, and not 3504, as given by Tryon, the 

 Buccinum niveum described upon that page being a species 

 of Terebra. 



The generic name Nassaria is rejected by Fischer (Man. 

 Conch, p. 631) in favour of Hindsia, but upon what grounds 

 is not evident. Nassaria, as established by Link, included 

 a variety of species which are at the present time ranged
