Rio de Janeiro (Perrier, Mas. Paris). A young specimen, probably 

 of this species, was collected in Botafogo Bay, Kio de Janeiro; and 

 two larger specimens, agreeing perfectly with the small one from Rio, 

 were obtained in the Bay of Bahia (Rathbun). N. Carolina — Florida ; 

 West Indies (Perr. and Verrill).

This Ophiuran is one of the commonest on the northern and cen- 

 tral coasts of Brazil ; but it has not been recorded from south of the 

 Abrolhos Islands. It is generally found between high and low water 

 marks, under stones in the shallow pools of the rocky shores and coral 

 reefs, in which situations it often occurs in great abundance. The 

 largest specimens obtained were from Fernando de Noronha. One of 

 these afforded the following measurements; diameter of disk, 37""", 

 length of arm, 210'"'".
