There is much variatioD iu the color of the spines which, toward the 

 base, are frequently of a light drab (hay color), changing to greenish 

 or a distinct green toward the tips, the latter being almost invariably 

 marked with dark purple for a greater or less distance. The principal 

 deviations from the above coloration depend upon the extent to which 

 the green approaches the base of the spine, and the intensity of that 

 color, becoming sometimes a dark olive green. The drab color is always 

 apparent at the base of the spines, and the milled head is always whitish. 



Toxopneustes variegatus, A. Agassiz. 



Key West, Florida; one small siiecimen, var. caroUnus (8410). 



Island of St. Thomas ; numerous specimens, with long, slender spines 

 and a greenish color, from the shore (7516, 8408); one young specimen 

 dredged in shallow water (8407). 



Jamaica; a series of specimens, similar to those from St. Thomas 

 (8409). 



Island of Curasao, off the coast of Venezuela ; three specimens (8406, 

 8827), one of which (8827) is of unusually larger size. This large speci- 

 men measures 00""" in diameter and 46'"" in height, and has 27 coronal 

 plates in the interambulacra; the anal system is 9""" in diameter, and 

 the actinostome 26""'". The primary s[)ines on the dorsal surface are 

 about 12" '" in length, and at the ambitus about 16"^". The bare median 

 interambulacral space is very broad, and reaches to the ambitus. 



Sabanilla ; two specimens of medium size, with comparatively short 

 and slender spines (8826). 



San Antonio, Cuba ; one very young specimen, referred doubtfully to 

 this species (8411). 



Station 2138 ; latitude 17° 44' 05" N., longitude, 75° 39' W., 23 fathoms; 

 one specimen (8415). 



Station 2159; latitude 23° 10' 39" N., longitude, 82° 20' 08" W., 98 

 fathoms; three specimens (8416). 



Station 2164 ; latitude, 23° 10' 39" N., longitude, 82© 20' 29" W., 192 

 fithoms; one specimen (8413). 



Station 2166 ; latitude 23° 10' 36" N., longitude, 82© 20' 30" W., 196 

 fathoms; one specimen (8414). 



Station 2167 ; latitude 23° 10' 40" N,, longitude 82° 20' 30" W., 201 

 fathoms ; two specimens (8412). 



The specimens obtained from the several dredging stations were all 

 of very small size.
