 Euryeope latirostris, G. 0. Sars, Oversigt of Norges Crustaceer, I. p. 67, PL 2, fig. 6. 



Specific Characters. — Very like E. phallangium as to its external appear- 

 ance. Frontal part of cephalon, however, very different, forming a broad lingui- 

 form plate slightly emarginated at the tip, and minutely denticulated outside. 

 Fifth and 6th segments of mesosome, as in E. phallangium, confluent in the 

 middle. Caudal segment comparatively larger* than in that species, but of a 

 similar shape and armament. Inferior antennae scarcely more than twice the 

 length of the body, with the flagellum much longer than the peduncle. Ambula- 

 tory legs of a similar structure to those in E. phallangiiim, though not nearly 

 so much elongated. Natatory legs with the dactylus scarcely attaining the length 

 of the propodal joint. Uropoda with the outer ramus shorter and narrower than 

 the inner. Colour about as in E. phallangium. Length of adult female 2 mm. 



HemarJcs. — This species is very nearly allied to E. phallangium, and 

 may indeed easily be confounded with it. On a closer examination, however, 

 some well-marked differences are to be found, showing it to be in reality a well- 

 defined species. Thus the frontal part exhibits a totally different appearance, 

 being rather broad, linguiform, and slightly emarginated at the tip, whereas in 

 E. phallangium this part tapers to a point. Moreover the inferior antenna? and 

 the ambulatory legs are less elongated, though of a similar slender form to those 

 in E. phallangium; finally, the dactylus of the natatory legs is much shorter, and 

 the rami of the uropoda are shorter and thicker. 



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

 my notice. That first described was found in the outer part of the Hardanger 

 Fjord. Some other specimens were subsequently detected on looking over a great 

 number of E. phallangium taken in the inner part of the Stavanger Fjord from a 

 depth of 150 to 200 fathoms.

Specific Characters. — Body oval, greatest width exceeding half the length,

 produced, forming a narrow, conical plate, minutely bifurcate at the tip, and ex-
