350 BE. H. J. HANSEK ON THE 



concave. Exopod somewhat shorter than the endopod, more 

 than four times longer than broad, " without any marginal 

 spinules." 



Length of the largest specimen known 33 ram, (Dollfus) ; 

 Hoek's typical specimen measured 23 mm. 



Occurrence. — Hoek's single specimen was captured in iat. 73° 

 13' 5" N., long. 30° 42' E., 166 fathoms. Sars has seen one 

 specimen from lat. 70° 36' N., long. 32° 35' E., 148 fathoms, and 

 a second from Storeggen (western coast of Norway), 50 fathoms. 

 Dollfus records a single specimen from lat. 65° 41' IST., on the 

 coast of Norway, 440 m. 



WRemarJcs. — This species is easily distinguished from all other 

 forms hitherto found in Europe by the shape of the seventh 

 thoracic legs ; the small black eyes, the very short antennse, the 

 end of abdomen, &c., exhibit other good characters. 



Unfortunately I have seen no specimen of this interesting 

 form ; my diagnosis has been compiled from the descriptions of 

 the three authors in question, to which I add characters to be 

 seen especially on the figures given by Sars. It was necessary 

 to do so, because the descriptions named are rather incomplete ; 

 furthermore, no figure of the thoracic epimera, seen from the 

 side, has been published, and these epimera have not been 

 described. 



The species is rather closely allied to G. concliarum, Stimps., 

 C. polita, Stimps., and C. impressa, Harger, all from the eastern 

 coast of the United States. It is to be hoped that a more 

 detailed description with some additional correct figures may 

 soon be published, so that it may be easily distinguished from 

 the American species mentioned; moreover, I do not think it 

 impossible that one of these American forms may eventually be 

 discovered in European seas. 



Group B. 



Frontal plate at most half as long again as broad. Three 

 posterior pairs of thoracic legs without natatory setas, or at most 

 with a few plumose setse at the outer margin of second joint.
