Diadema setosum, Gray. 



This species was collected at the following localities : 



Key West, Florida; oue specimen (7497). 



St. Thomas ; several specimens from the shore, and from shallow 

 water by dredging (7493, 7494, 7495, 8431). These form a very complete 

 series, ranging from the young to large individuals. 



Old Providence Island ; several large specimens (7492, 7496). 



Curasao ; one small specimen (8430). 



Station 2139 ; latitude 17° 52' N., longitude 7Go 45' 30" W., 215 fath- 

 oms; one small specimen (8429). The spines of this specimen are 

 banded, as in most of the young specimens from the shore, but the 

 darker bands are of a light reddish brown color instead of the customary 

 bluish black. This same color occurs, however, to a slight extent on 

 some of the shore specimens.
