Fyes small, circular. Superior antenna- in female nearly as I'm- as 1 1n- 

 inferior, flagellum longer tlian the peduncle, (i-articnlate; in male onlv slightlv 

 reacliing beyond the peduncle of the latter. Posterior gnathopoda in female 

 a little larger than the anterior, propodos of both pairs about as h>ng as tin- 

 J preceding joints combined, elongated quadrangular, palm transversely 1 runeat cd 

 and defined below by an almost right angle. Anterior gnathopoda in niah- 

 having the propodos somewhat broader ilian in female, with the palm evenly 

 curved; posterior ones very largely developed, propodns oval, scarcely 

 tapering, palm obliquely arcuate and defined l>elo\v by an ohtuse project inn. 

 Propodal joint of the pereiopoda scarcely dilated, having tnl't- of small spines 

 on the inner edge, dactylus comparatively small. Last pair of uropoda with 

 the ramus scarcely more than half as long as the basal part and terminating 

 with a tuft of short spines. Telson about twice as In-oad as it is long. lohe- 

 nacked and angular in form. Colour greenish. Length of adult female <i 7 

 mm, of male 8 mm. 



llcniarlcs. - As pointed out by the Rev. Mr. Stebbing, Boeck has errone- 

 ously confounded this and the following species. Tin- habitus-figure <d' tin- 

 female given by that author as also the figure of the -Jml gnathopoda of the 

 male, undoubtedly refer not to RathkeV species but to the form described 

 below as//", liiltljocli'unui. From that species the present form is easily known 

 by the different structure of the gnathopoda, as also by that of the terminal 

 part of the pereiopoda, 



Occurrence. - - The present species would seem to occur along the whole 

 coast 'of Norway, from the Christianiafjord up to Vardo, where it has been 

 recently found by Mr. Schneider, curator of the Tromso Museum. I have myself 

 taken it in several places on our west coast, near ordinary tide-mark, between 

 sea-weed. It is very active and, when out of water, has a similar power of 

 making abrupt leaps as the Talitri and Orchestise. 



Distribution. - -Atlantic coast of Europe: 15ohuslehn, Denmark, liritisli 

 Islands, France; Adriatic (Heller); Azores (Barrois

Segments of body rather sharply demarcated from each other, giving the 

 back a subimbricated appearance. Integuments on the whole much firmerthan 

 in H. Nilssoni, the edges of the coxa! plates thickened and slightly crenulated.
