serrated, acts and forms a strong prehensile grasp. The 
last pair of caudal appendages have the branches short, 
the inner being broadly foliaceous, the outer tipped with 
two short hooks ; the telson terminates in a strong and 
well-formed hook, that is evidently intended for some 
special purpose. 
We have received specimens of this species, of which 
the habits are unknown, from the Moray Frith, where 
they were taken by the Rev. Geo. Gordon ; from Rock- 
pools, Penzance, where they were 7 found by Mr. Harris. 
They have been sent to us from the Shetlands, by the 
late Mr. Barlee ; and the Rev. A. M. Norman has 
dredged them in from two to five fathoms in the Outer 
Skerries harbour in company with Mr. Jeffreys.
