Fontocrates arenarius has not as yet been found in Xorway. 

 The species which Sars figures under that name (Supplement, 

 pi. vi., fig. 2, pi. vii., fig. 1) must bear tlie name Poutocrates 

 norvegicus Boeck. As far as our observations go the latter 

 species is more generally met with on our coasts than P. 

 araiarius. Hoek, on the plate referred to, has given an 

 excellent figure of the second gnathopod of P. arenarius, 

 the carpus of which is rounded at its extended point, whereas 

 in P. norvegicus it is hollowed like a little spoon (Sars, Supp., 

 pi. vi., fig. 2); there is still greater difference in the first 

 gnathopod, which in arenarius has a very oblique palm (as 

 in P. al/amarinus, see Sars, Supp., pi. vii., fig. 2), whereas
