554 THE VOYAGE OF H.M.S. CHALLENGER. 
Paciric: 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. *EHchin- 
aster eridanella, off the Admiralty Islands, New Caledonia, and 
New Ireland. Lchinaster.tenuispinus, off the coast of California. 
Echinaster cribella, off the coast of Chili. 
8. Bathymetrical range: Probably all the species are confined to the Littoral zone, 
with the exception of Echinaster modestus, which is stated by Perrier’ to occur 
in 309 fathoms. 
y. Nature of the Sea-bottom: Echinaster spinulifer is found on Voleanic 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, Miller and Troschel. Echinaster lacunosus, Grube.

* Nouv. Archives Mus. Hist. Nat., 1884, 2e Série, t. vi. p. 179. The greatest depth of this species is 
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.
