ECHINODERMATA. 
Most of the Echinodermata enumerated last year were again 
taken this season, in still greater abundance, and several addi- 
tional species were discovered. Among the latter are four 
species of Archaster, one of which is new ;* one of the curious 
large specimens of Dorocidaris papillata ; the European Kchino- 
cyamus pusillus ; three species of Spatangoids (Spatangus pur- 
pureus, Brissopsis lyrifera, both Kuropean species, and a Schizas- 
ter, like S. canaliferus); but the last two were also taken in 
1880, though not then enumerated. 
The Astrochele Lymani V., occurred at 939, 1028, 1029, in 
abundance, twining its arms closely around the branches of 
Acanella Normani V. It had before occurred off Nova Scotia 
.

Schizaster canaliferus L. Agassiz (? variety). 
A number of specimens of this singular Schizaster have been 
taken at several stations, in 65-130 fathoms. It is closely 
related to the Mediterranean form, S. canaliferus, and to the spe- 
cies, S. Orbignyanus, recently described from the Gulf of Mex- 
ico, by Mr. A. Agassiz. Some of the specimens were sent to 
Mr. Agassiz, who thought them allied to the last named spe- 
cies, but as he had no time to study them carefully, he kindly 
bulacrum. It differs from both the forms named, in having the 
* These species are A. arcticus Sars, 183-310 fathoms; A. tenuispinus D. and 
K., 388 fathoms; A, mirabilis Perrier (?), 310 fathoms ; and A. Bairdii, sp. nov-; 
388 fathoms.
