chart) ; and I dredged also two specimens off Rodberg, in 

 250-300 fathoms, the latter spot being only a few miles from 

 Sars's locality. II. avculus is distinguished by its want of 

 eyes, the acutely produced lateral angles of the head, the 

 produced lower hind margin of the third segment of the pleon, 

 and the slender second gnathopods ; but the peculiarity which 

 at once attracted my notice as belonging to a species new to 

 me consisted in the very slender nails of the pergeopods, which 

 recalled those of Tnjj/iosites longipes. 



81. Uroihoe norvegica^ Boeck. 



In various dredgings down to 150 fathoms. I employ 

 this name as certainly correct when applied to this form 

 without expressing any opinion as to the British species, 

 with which it must be synonymized, because I have not 

 again carefully examined the latter since the publication of 

 Stebbing's memoir on the genus. Delia Valle has united the 

 whole of the northern forms, including U. ahhreviata., G. O. 

 Sars, together with Egidia pulcliella, A. Costa, and U. Pouchetiy 

 Chevreaux, under the name Urothoe irrostrata, Dana; and 

 he maintains that marked differences occur in the third pergeo- 

 pod of the two sexes {cf. his pi. xxxvi. figs. 14, 15). Now 

 specific characters have been drawn partially from the 

 different structure of this limb. The point therefore is of 

 consequence, for Sars shows that the form of this limb is 

 not affected by sex in the case of U. norvegica. Stebbing's 

 elaborate memoir on this genus in Trans. Zool. Soc. vol. xiii. 

 p. 1, should be consulted.

A glance at the very peculiar little hook-formed last joints 

 of the peraiopods at once suffices to distinguish this species 

 from all others known to me. A single specimen, Trondhjem, 

 between Monkholmen and the shore.
