Two or tliree specimens in CyprkUna norvegica from off 

 Eodberg ; also taken by me in the Hardanger Fiord. Sars'a 

 type specimens were from the Lofoten Islands. 



Kossman has instituted the genus Cyproniscus to receive 

 this species.

The beautiful new work on the Amphipoda of Norway by 

 Prof. G. 0. Sars *, which is now almost completed, throws a 

 flood of light upon this interesting group, and will henceforth 

 make the study of the northern species comparatively easy. 

 The descriptions and the figures in this monograph leave 

 nothing to be desired. The great work of Delia Valle lately 

 published (' Fauna und Flora des Golfes von Neapel, Gam- 

 marini del Golfe di Napoli/ 1893) also adds much to our know- 

 ledge of the South European species ; to this work I shall 

 have occasion to, in some cases, refer f. I have followed 

 Sars's arrangement. 



In the opening sentences of these notes I mentioned that a 

 cliief reason of my going to the Trondhjem Fiord was a hope 

 that by doing so I might meet with some of the new and rare 

 Amphipoda which G. O. Sars had found there. I was not 

 disappointed. The following list of 119 species is a good 

 record for a month's work. Some of these species are not 

 recorded from the Fiord by Sars; but he has given that 

 locality for 70 species which were not obtained by me, and to 

 these numbers must doubtless be added many of the commoner 

 forms of West Norway, for which Sars in his work does not 

 record special habitats. It will be evident how rich the 

 Amphipodal fauna of this Fiord must be, when I mention 

 that in Stebbing's great work on the ' Challenger ' Amphipoda 

 the number of described species is 294 ; but of these no less

 pts. 1-80, pis. i.-ccxl. (1890-94). 



t It is much to be regretted that Signor Delia Valle has added to his 

 work synonymy of Arctic species, with which he was not familiar. With 

 respect to these much confusion hns been introduced by the lumping 

 together of widely distinct species under a single name. No naturalist 

 who waspractically acquainted with the species, or, at any rate, had studied 

 them in life, could have thus treated them.
