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-g- inches. It is 

 not unlikely that these 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. 

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



Carapace without lateral crests. Upper edge of rostrum 

 armed with fixed teeth as well as movable spinules. Basal 

 lobe of antennules broad and rounded. Scaphognathite 

 with posterior lobe truncated (PI. II. fig. 4, c). Second pair 

 of perasopods unequal, carpus of the longer multiarticulate.
