only found in comparatively shallow water, especially where the bottom is 

 overgrown by grass, and in such places often occurs in great abundance. 



Distribution. British Isles (Sp. Bate), Bohuslan (Bruzelius), Kattegat 

 (Meinert), Dutch coast (Hoek), coast of France (M.-Edw.), Mediterranean (Costa), 

 Azores (Barrois).

Body rather slender, though scarcely to such a degree as in E. cliff or- 

 DI is. Cephalon moderately elongated, with the lateral lobes comparatively 

 broad, and produced at the tip to a small, somewhat upturned, dentiform pro- 

 jection. Second pair of coxal plates much smaller than the 5th, the latter 

 with the anterior lobe very large and broad. Eyes rather large, rounded. 

 Antennae very much elongated and densely setiferous posteriorly, last peduncular 

 joint of the superior ones somewhat shorter than the 2nd. Anterior gnatho- 

 poda with the propodos comparatively less expanded than in the 2 preceding 

 species, and scarcely as long as the carpus. Posterior gnathopoda in female 

 having the carpal lobe rather broad at the base and subtriangular in form; 

 those in male, as usual, strongly developed, carpus scarcely twice as long as 

 it is broad, and produced at the end below to a comparatively short and 

 simple acute process, not reaching beyond the middle of the propodos, which 

 is oblong oval in form, with the lower edge straight and provided with 

 a lamellar, projecting border divided in the middle by a small incision, 

 dactylus not very large, and without setae. Basal joint of the 2 anterior pairs 

 of pereiopoda considerably expanded; the 2 posterior pairs rapidly increasing 

 in length, the last pair being rather slender and elongated. Uropoda and 

 telson about as in the 2 preceding species. Colour in the living state of the 

 animal not yet stated. Length of adult male 5 mm. 



Remarks. This species was first described by Sp. Bate from a specimen, 

 the locality of which was not stated, and was subsequently recorded by Boeck 

 from Norway. It may easily be distinguished from either of the 2 preceding 

 species by the rather different structure of the posterior gnathopoda in the male. 



Occurrence. Only a few specimens of this form have hitherto come 

 under my inspection. They were found off the west coast of Norway (the 

 exact locality not being stated). Boeck found it at Haugesund. 



Distribution. Kattegat (Meinert).
