[Plates I.-IV.] 



In a paper " On Deep-sea Crustacea from the South-west of 

 Ireland " * I lately recorded the occurrence for the first time 

 in British waters of two species of Pandalus, referred to the 

 P . jyropinquus and P. leptorhynchus of G. O. Sars, in addition 

 to the two already known to occur in our seas — P. Montagui, 

 Leach, and P. hrevirostris, Rathke. In the present paper 

 brief descriptions and figures are given of the more important 

 diagnostic characters of these four species, some of which 

 characters have not hitherto been pointed out. 



In his account of the Crustacea dredged by the ' Caudan ' 

 in the ]3ay of Biscay M. Maurice C!aullery has recently 

 described f a species of Pandalus differing from all the 

 members of the family hitherto described in possessing on
