THE VOYAGE OF H.M.S. CHALLENGES. 



Pacific : Four species between the parallels of 40° N. and 45" S. 



Echinaster fallax, from New Zealand {fide Perrier), and ex- 

 tending into the Eastern Archipelago and Indian Ocean. *Echin- 

 aster eridanella, off the Admiralty Islands, New Caledonia, and 

 New Ireland. Echinaster tenuispnnus, off the coast of California. 

 Echinaster cribella, off the coast of Chili. 



ft. Bat hy metrical range : Probably all the species are confined to the Littoral zone, 

 with the exception of Echinaster modestus, which is stated by Terrier 1 to occur 

 in 309 fathoms. 



y. Nature of the Sea-bottom: Echinaster spinulifer is found on Volcanic mud ; other 

 species not recorded. 



The species collected by the Challenger Expedition are indicated in the foregoing list 

 by an asterisk. 



The localities of the following species are unknown, and they have consequently not 

 been included in the lists given above : — 



Echinaster crassus, Miiller and Troschel. 

 Echinaster deplanatus, Grube. 



Echinaster lacunosus, Grube. 

 Echinaster rigidus, Grube. 



Chorological Synopsis of the Species herein mentioned.

 stated (op. cit.) on p. 206 to be 123 fathoms ; but on p. 179 of the same work an example is recorded from 309 

 fathoms from a different locality from those cited on p. 206, although it bears the same station number (No. 

 170) as one_of them.
