Murecc aculeatus, Lamarck. 



Hab. Off south coast of Ceylon, 34 fatli. {' 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. Viv. 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.

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