Bay of Bengal and the Arabian Sea. 463 



Murex aculeaius, Lamarck. 



Hab. Off south coast of Ceylon, 34 fath. (/ Investigator ') ; 

 Tizard Bank, China Sea, 20 fath. (H.M.S. 'Rambler/ in 

 Brit. Mus.). 



The specimens from the above localities more closely agree 

 with Kiener's figure (Coq. Yiv. pi. xxxix. figs. 3) than with 

 the shell depicted by Reeve (Conch. Icon. vol. iii. fig. 60). 

 They have a single intermediate tubercle or plication between 

 the varices, and exhibit some transverse fine reddish lines, as 

 shown in Kiener's figure. On the other hand, Reeve's shell 

 has two intervening plicae and only faint traces of the spiral 

 lineation. 



Phos roseatus, Hinds. 



P/ios roseatus, Hinds, Voy. ' Sulphur,' Zool. vol. ii. p. 38, pi. x. figs. 9,

Hab. Off south coast of Ceylon, 34 fath. 



A more slender and more finely sculptured form than that 

 figured by Try on and Sowerby. The species occurs at 

 Sumatra, the Philippines, Moluccas, &c. 



Nassaria suturalis (A. Adams). 



Hindsia srduralis, A. Adams, Proc. Zool. Soc. 1853, p. 183; Kobelt,

Nassaria suturalis, Sowerby, Thes. Concb. vol. iii. p. 86, pi. cexx. 

 figs. 15, 16; Tryon, Man. Conch, vol. iii. p. 221, tig. 542 (acumi- 

 nata, part.). 



Hab. Off south coast of Ceylon, 34 fath., and eight miles 

 south of Puri, Bengal, 13 fath. (' Investigator ') ; Malacca 

 (A. Ad.); Ceylon {Layard). 



N. bitubercularis, A. Adams, from Sorsogon, Philippine 

 Islands, is a synonym. 



Nassaria nodicostata (A. Adams). 



Hindsia nodicostata, A. Adams, Proc. Zool. Soc, 1853, p. 183 ; Kobelt,

Nassaria nodicostata, Sowerby, Thes. Conch, vol. iii. p. 86, pi. cexx. 

 fig. 13. 



Hab. Station 239, off Andaman Islands, in 55 fath. (' In- 

 vestigator') ; ? (A. Adams). 



This so-called species is probably only a small variety of 

 N. acuminata, Reeve, from China, with which it has been 

 united by Tryon * together with half a dozen other species.
