light fuscous, tinged towards the edges of the segments with chestnut. Length 

 of adult female scarcely exceeding 1 mm. 



Remarks. — This dwarf species is evidently closely allied to E. mutica, but 

 is of still smaller size, and is moreover distinguished by the somewhat different 

 form of the frontal part of the cephalon, the comparatively shorter inferior an- 

 tenna?, the peculiar shape of the dactylus of the natatory legs, and finally by the 

 much paler colour of the dorsal face. 



Occurrence. — The only place where I have met with this form, is off the 

 Lofoten Islands, at Skraaven. It occurred here rather sparingly in a depth of 

 about 120 fathoms, sandy clay. Out of Norway this species has not yet been 

 recorded.

Specific Characters. — Body oblong oval, greatest width not attaining half 

 the length, and ocem'ring about in the middle. Frontal part of cephalon rather 

 produced, linguiform, slightly excavated, and distinctly emarginated at the tip, 

 lateral edges minutely serrate. Anterior segments of mesosome of normal ap- 

 pearance, with the lateral parts slightly denticulate at the distal edges ; 5th and 

 6th segments distinctly defined above, and rather large, with the lateral edges 

 denticulate; 7th segment very short, almost band-shaped. Caudal segment of 

 considerable size, fully equalling in length the 3 preceding segments combined, 

 and subtriangular in form, with the tip narrowly rounded. Superior antenna? in 

 female of normal appearance, in male very largely developed, extending to the 

 end of the penultimate joint of the inferior antenna?, flagellum composed of about 

 16 articulations clothed with long, band-like sensory appendages. Inferior antennse 

 scarcely attaining twice the length of the body, the 2 outer joints of the peduncle 

 rather strong, and edged with numerous slender spines, flagellum about the length 

 of the peduncle, and very narrow. Molar expansion of mandibles conically tap- 

 ering. Maxillipeds very strongly built, with the penultimate and antepenultimate 

 joints greatly expanded, the former terminating outside in an acute projection, 

 the latter having the inner expansion angularly produced at the tip, epignath 

 large, lanceolate, with the outer edge sharply curved in the middle. 1st pair 

 of legs with the 2 outer joints very narrow, the carpal one being much the longer; 

 the 3 succeeding pairs unusually robust, and not nearly attaining the length of 

 the body. Natatory legs with the propodal joint considerably expanded, almost
