ANONYX LONGICORNIS. 93 



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 tliis 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.
