642 THE VOYAGE OF H.M.S. CHALLENGER. 



Station 186. September 8, 1874. Lat. 10° 30' S., long. 142° 18' E. Wednesday 

 Island, Cape York, North-east Australia. 8 fathoms. Coral mud. 



Habitat. — Lord Hood's Island (Adams) ; Mauritius and Polynesia (v. Martens). 



It is scarcely possible to admit this species into the genus Atys. The outer lip is not sinuated, 

 and can hardly be said to rise at its insertion. I believe it would be better to class it with 

 Cylichna.
