second or squamose joint posteriorly and inferiorly pro- 
duced, so as to cover the third joint and part of the 
fourth: the fourth joint is very peculiar, being pos- 
teriorly developed to a squamose plate, with the upper 
and lower margins posteriorly depressed, and almost 
parallel, as are also the anterior and posterior margins — 
circumstances that give to the joint the form of a 
diagonal parallelogram. The wrist is very long, longer 
than the hand, and stouter ; the hands have the margins 
parallel ; fingers long, slender, and straight. The two 
posterior pairs of legs are subequal, and considerably 
longer than the preceding. The caudal appendages 
are subequal in length ; the two anterior pairs are 
free from hairs or spines, and reach to the same dis- 
tance, the branches being equal. The posterior pair 
have the branches equal to each other in length, but 
a little longer than those of the two preceding pairs ; 
they have the inferior margin straight, or nearly so, 
tending rather to a hollow than to a convex outline, 
while the upper margin is arcuate, and furnished with 
a thick fringe of hairs. The terminal plate is very 
long, reaching to two-thirds the length of the posterior 
pair of caudal appendages. 
We received this interesting specimen from our valued 
friend and correspondent, Mr. Geo. Barlee. He obtained 
it, with many other Crustacea, from the Haaf fishing- 
grounds off the coast of Shetland.
