Unless the " Asterias aranclaca " mentioned by Dr. Gould as 

 taken from the mouth of a cod fish, was the young of this species, it 

 may indicate the occurrence of a species of Astropecten in this region.

Asterias (Asteracanthlon) polaris (M. and Tr. sp.) 



A specimen obtained at St. George's Bank, in thirty-five or forty 

 fathoms, by Capt. N. E. Atwood, belongs to the Collection of this 

 Society. This is 10.5 inches in diameter, disk 1.75 broad, arms 0.8. 

 wide at base. The dorsal surface Is less evenly spinose than In ordi- 

 nary Labrador specimens, there being scattered, long, cylindrical, ob- 

 tuse spines, while the majority of the spines are quite small and less 

 capitate than usual. The lateral and ventral spines, the pedlcellariae, 

 and the form of the six rays agree well, however, with this species.
