THE VOYAGE OF H.M.S. CHALLENGER. 



Strait, extending to Mozambique in the Indian Ocean and to the Fiji 

 Islands in the Pacific. Culcita schmideliana, from Amboina, and 

 extending into the Indian Ocean to the East Coast of Africa, and {fide 

 Gray) into the Pacific to the Galapagos Islands. Culcita grex, from 

 Molucca (Leyden Museum). 

 Pacific : Three or four species between the parallels of 30° N. and 20° S. 



Culcita acutispina, from the New Hebrides. Ctdcita arenosa, from 

 the Sandwich Islands. Culcita pentangularis, from the Fiji Islands, 

 and extending into the Eastern Archipelago and the Indian Ocean. 

 Culcita novae-guineas is recorded from New Hanover by Studer. 

 The occurrence of Ctdcita schmideliana in the Pacific (Galapagos 

 Islands, fide Gray), still needs authentication. 



/?. Bathy metrical range : Shallow water.

Remarks. — Examples of this form may be selected which correspond exactly to the 

 type of Gray's Culcita pentangularis. After a careful study, however, of the various 

 examples referable to Culcita novse-guineai which I have been able to examine, I am 

 unable to indicate any characters by which these two forms can be separated specifically,
