from deep water, especially those taken in Loch Fyne, have 

 the beautiful red tinge so characteristic of deep-sea Crustacea," 

 and he gives the size of large specimens as 4^ inches. It is 

 not unlikely that tiiese large red-coloured specimens from 

 deep water belonged to the present species. One of our 

 specimens, after several years' preservation in glycerine, still 

 shows traces of a brilliant red coloration, especially on the 

 anterior part of the carapace and on the legs. 



The P. leptocerus of Smith (Proc. U.S. Nat. Mus. iii. 

 p. 437, 1880; Bull. Mus. Comp. Zool. x. p. 58, 1882-83 ; 

 A. Milne-Edwards, ' Recueil de Fig. de Crustaces nouveaux 

 ou peu connus,' 1883) is very closely related to the present 

 species, from which, however, it is at once distinguished by 

 the minutely scabrous surface of the body. The Pandalus 

 falcipes of Spence Bate (Rep. Chall. Macrura, p. 698, pi. cxv. 

 tig. 2) is, perhaps, identical with Smith's species.
