ECHINOCARDIUM FLAVESCENS. 263 



coasts of New South Wales and Victoria. The only coastal regions aside from 

 the East Indies * where cordatum is not known to occur are the western side of 

 Africa, the southern and western parts of South America, the western coast 

 of the United States and British North America, the southwestern coast of Asia, 

 the northeastern shores of Africa, and the islands of the tropical Pacific. In 

 some of these regions at least, it is very sure to be found, when the marine fauna 

 is well worked out. The bathymetrical range is quite limited which is rather 

 remarkable for so wide-ranging a form, but this may account for its absence from 

 the Pacific Islands. The record in the Challenger report of australe collected 

 at Station 234, in 2675 fms., is undoubtedly an error, 2 as no dredging or trawling 

 was done at that station; there is little question that the specimens were taken 

 at Station 233, off Kobe, Japan, 12-15 fms. So far as hitherto recorded then 

 the range of cordatum bathymetrically is 0-85 fms.

Ten specimens. 



Echinocardium mediterraneum. 



Amphidetus mediterraneus Forbes, 1844. Proc. Linn. Soc. London. 1, p. 183. 

 Echinocardium mediterraneum Gray, 1855. Cat. Rec. Ech. Brit. Mus., p. 44. 



This species is as yet known only from the Mediterranean Sea, and from 

 the coast of Portugal, in 1.5-23 fms. 



Echinocardium flavescens. 



Spatagus flavescens O. F. Miiller, 1776. Zool. Dan. Prod., p. 236. 

 Echinocardium flavescens A. Agassiz, 1872. Rev. Ech., pt. 1, p. 110. 



This species is known from Northern Norway and Iceland to the Mediter- 

 ranean and doubtfully from the Azores, at depths of 5-156 fms. It is also 



1 Mr. Agassiz records in the Revision a specimen from "East India."
