Fara. Temoridse. 

 Genus Hetekocope, G. 0. Savs, 1863. 



Ileterocope appendicuJata, G. O. Sars.

 Ferskvandes-Copepoder, p. 224. 



Specimens of this Heterocope occurred very sparingly in 

 the gathering from the lake at Kirkenes containing the 

 Diaptomus graciJoides. The appendages on the underside 

 of the first abdominal segment of the femaJe appear to be 

 peculiar to this sp,ecies. G. O. Sars speaks of it as abundant 

 in the great lakes of Norway, and it has been recorded by 

 Nordquist from several lakes in the south-east of Finland. 

 The species seems to have a wide distribution in Northern 

 Europe. 



Fam. Cyclopidse. 

 Genus Cyclopina, Glaus, 1863. 



Cychpina gracilis, Glaus. 



1863. Cychpina gracilis, Clans, Die frei lebenden Copepoden, p. 104, 

 t. X. figs. 9-15. 



This species was observed sparingly in a gathering from 

 Vadsoj but in none of tlie others ; it appears, however, to 

 have a wide distribution, 



Cyclopina Schneidei'i, sp. n. (PI. I. figs, 1-6.) 



Description of the female. — The specimen represented by 

 the drawing (fig. 1) measures rather more than 1 millim. in 

 length. The cephalothorax, which is moderately robust, is 

 fully one and a half times the length of the slender abdomen. 

 The forehead is rounded, and the antennules, which scarcely 

 reach to the end of the cephalic segment, are composed of 

 twelve joints (fig. 2), The structure of the antenimles 

 resembles very closely that of the antennules of Cyclopina 

 gracilis, Claus ; but in the present species there are six small 

 end joints, instead of five. The formula shows approxi- 

 mately the proportional lengths of the various joints : —

Tlie antennae also resemble the same appendages in Cyclopina 

 gracilis; they are composed of four joints, the penultimate 

 one being the shortest (fig. 3).
