of this species, was collected in Botafogo Bay, Bio de Janeiro; and 
two larger specimens, agreeing perfectly with the small one from Rio, 
were obtained in the Bay of Bahia (Rathbun). X. Carolina — Florida ;

Tb is 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 Nbronha. One of 
these afforded the following measurements; diameter of disk, 37 mra ) 
length of arm, 210 mra .
