 surface ; the other parts pale sap-green. 



Variations. — The number of arm-spines varies from four to six, or 

 even seven ; and this does not seem entirely to depend on size. The 

 color, in alcohol, is usually some shade of green, either plain sap or 

 olive green, or bright green mottled and banded with yellowish. Occa- 

 sionalh' the color of the upper parts is deep brownish-green. Liitken's 

 figure, which is not correctly drawn, gives the color as red (l)urnt-lake). 

 A colored drawing of the living animal, belonging to Professor Agassiz, 

 is yellowish orange (yellow ochre and orange chrome), with a few 

 lighter bands near the ends of the arms. Probably the color varies 

 through several tints of red and of orange. 



This species has been taken, in from three to five fathoms of water, 

 at Santa Cruz and St. Thomas (Orsted, Riise). At the latter place Mr. 

 Riisc has found it in the holes made in corals by boring mollusks. It is 

 not uncommon on the coast of Florida, near low-w'ater-mark. 



Say's description was evidently from a dried specimen, as he mentions 

 the row of overlai^ping scales along the upper margin of the disk.
