Asterias spinosus (pars') Say, 1. c. p. 142. 



This species, well described by Dr. Stimpson, is very abundant in 

 Long Island Sound in six to twelve fathoms, muddy bottom, and also 

 occasionally at low water. It extends southward to South Carohna 

 and Georgia. Its color, when living, is dark green, with a bright 

 orange madreporic plate. Occasionally it is brownish. 



Asterias (Asteracanthion) compta Stimp. 1. c. p. 270. 



Found on a bank off the coast of New Jersey in thirty-two fathoms, 

 associated with Zoanthus Americanus^ Eupagurus puhescens, etc. 

 Whether this locality belongs to a southern extension of the Acadian 

 Fauna, or is one of the few known, deep-water localities of the Vir- 

 ginian Fauna seems somewhat doubtful.

This species occurs frequently on sandy bottoms, in six to twelve 

 fathoms in Long Island Sound, off New Haven. Also near the north- 

 ern shores of Long Island. It is far more abundant and larger in the 

 Bay of Fundy, and northward to Labrador.

Under the names first quoted, nearly all the American writers seem 

 to have confounded two closely allied species, which have been for the 

 first time distinctly separated by Liitken in the work cited. 



be considered an objection to it, since it is useless to go back of the origin of 

 the binomial system to establish names, and besides this, the double use of a 

 generic name in Botany and Zoology, although certainly undesirable, is not 

 usually regarded as a sufficient reason of itself for changing it; otherwise, we 

 should be obliged to change hundreds of names so employed at the present 

 time. The names Uraster Agassiz, and Stellonia Nardo, also, have the precedence 

 of Asteracanthion.
