240 RECENT OPHIURANS. 



than broad, narrower distally than proximally, "with rounded angles (especially 

 distally), slightly in contact throughout; distally they tend to become as wide 

 as long and are relatively larger compared to the width of the arm. Inter- 

 brachial areas below naked. Oral shields of moderate size, pentagonal with 

 rounded angles, widest proximally. Adoral plates small, roughly triangular, 

 not meeting proximal to oral shields. Oral papillae as in Amphiura; subdental 

 pair not peculiar; distal pair rather large, flat, longer than broad; papUlae 

 adjoining first oral tentacles conspicuous and very acute. Under arm-plates 

 longer than wide, the first two or three very much so; squarish, in contact 

 throughout, distal margin notched. Side arm-plates large but not meeting 

 either above or below; each one carries a series of 8 (or 7) dehcate, flattened blunt 

 arm-spines, most of which are more or less rough or minutely spiny at tip ; low- 

 est spine longest and much exceeding an arm-joint; the others successively 

 shorter to the uppermost which is very small. Tentacle-scales none. Color 

 (dried): — disk brown, radial shields and scales whitish; arms dull yellow with 

 numerous bands of blackish; each band 4 or 5 arm-joints wide. 



HoLOTYPE (M. C. Z. 3744). Torres Strait: Friday Island, on sandy flat, 

 under a stone. Sept. 13, 1913. Carnegie Exp. 1913. H. L. Clark coll. 



Notes on this specimen made the day it was taken read, "Colors red, blue, 

 and yellow, much dulled and paled in drying. Disk 8-10 mm." No doubt 

 it is very closely related to ecnomiotata from Japan but aside from the striking 

 coloration (the Japanese species shows no sign of banded arms), the form of 

 the distal oral papillae, the shape of the oral shields, and the number of arm- 

 spines, all preclude its being referred to that species.
