specimen of this sex. The males are also at once distin- 
guished by the peculiar form of the hand of the second 
pair of legs, which is of large size, strongly curved on 
its fore margin, whilst the posterior, or palm, is exca- 
vated; its distal extremity broadly but obliquely trun- 
cate, whilst its base is armed with an obtuse point, 
antagonizing with the tip of the finger, followed by a 
strong bent and recurved tooth. The first pair of legs 
are small, and the hand oblong-ovate ; this is also the 
form of the hands of the second pair of legs in the 
female, but the base of the palm is defined by a conical 
point near to the base of the joint. 
Our specimens (like those of Kréyer) have also lost the 
antepenultimate pair of legs, but in the two posterior 
pairs the joints are slender, naked, and destitute of spines 
or points, so as to appear quite simple. 
Several specimens of this species, collected by the 
Rev. J. Gordon in the Frith of Forth, exist in the Bell 
Collection of Crustacea, recently presented to the Uni- 
versity Museum of Oxford by Professor Westwood. 
They were obtained upon a shell brought up on a had- 
dock line on the 18th September, 1855.
