runs up to the tips as a broad margin to each arm. The arms 
are rather large, stout at base, with broad inner face, gradually 
tapering to very slender tips; the first and third pairs are 
nearly equal in length; those of the second are also about 
equal in length to the fourth pair, but are somewhat shorter 
than the first and third. The arms on the right side are all 
somewhat longer than the corresponding ones on the left. The 
arms, measuring from the beak, are more than twice as long 
as the body. ‘The suckers are arranged in two distinct rows, 
to the base. Color of head and body, above, and of body, be- 
neath, deep reddish-brown, closely specked with darker brown, 
and with many small roundish spots of whitish on the body 
and arms.

Brisinga Americana, sp. nov. 
A large and very showy species with fifteen to twenty long 
and very spinose rays, which are high and much compresse 
laterally near the base, but farther out become depressed and 
taper gradually to the slender ends. In our specimen the disk 
iS gone. Fifteen detached arms remain; some of them entire, 
but mostly broken, probably by the spontaneous contractions 
of the creature when taken. According to the statement of 
the captors it had twenty rays, originally. The longest rays, 
a preserved in strong alcohol, are 8538™™ (14 inches) long; 
Steatest height (about 1°5 inches from base) 82™™ (1°26 inches),
