Plate xxvi; figure 1. 



The ratios of the radii are about 1 :5. The rays are terete and 

 rather slender. The spines are numerous, small, acute-conical, 

 not much larger than the outer adambulacrals. On the rays 

 they form about nine to eleven rows in the adult, with thirty or 

 forty in the median row, in specimens 112™°^ in diameter. The 

 adambulacral plates have three spines. 



The spines are larger and fewer than in E. spinulosus, but 

 much more numerous and smaller than in E. sentus. 



Color in life rust-red, paler below. (Ives.) 



The figure of a portion of a ray given by Miiller and Troschel 

 does not agree with their description. It probably represents 

 E. senilis. 



This Brazilian species has been recorded from shallow water 

 on the Florida coast by Mr. A. Agassiz ; from Jamaica, by Liit- 

 ken and Verrill; and from Yucatan by Ives. On the Brazilian 

 coast it has been recorded from Pernambuco (Rathbun) to Rio 

 de Janeiro (Perrier). The Yale Museum has it from Bahia and 

 Pernambuco (coll. C. F. Hartt, Nos. 5206, 5208, 4559). Also a 

 specimen, perhaps of this species, from Cuba (No. 263). Mr. 

 Rathbun doubts the Rio de Janeiro record. Some of the other 

 records are also doubtful, owing to confusion with allied species. 

 That of Florida is doubtful. I have seen no specimens from 

 Florida nor from the Bahamas.
