G Canon A. M. Noinian — Xotes on the 



Fam. Temoridae. 

 Genus Heterocope, G. 0. Sars, 1863. 



Heterocope appendiculata, G. 0. Sars. 



1863. Heterocope appendiculata, G. 0. Sars, Oveisigt af de indenlanslie 

 Ferskvaiides-Copepoder, p. 224. 



Specimens of this Heterocope occurred very sparingly in 

 the gathering from the lake at Kirkenes containing the 

 Diaptomns graciloides. The appendages on the underside 

 of the first abdominal segment of the female appear to be 

 peculiar to this species. 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 th« south-east of Finland. 

 The species seems to have a wide distribution in Northern 

 Europe. 



Fam. Cyclopidae. 

 Genus Cyclopina, Glaus, 1863. 



Cychpina gracilis^ Glaus. 



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

 t. X. figs. 9-15. 



This species was observed sparingly in a gathering from 

 Vadso, but in none of the others ; it appears, however, to 

 liave a wide distribution. 



Cyclopina Schn€idert\ 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 lounded, and the antennules, which scarcely 

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

 twelve joints (fig. 2). The structure of the antennules 

 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 : —

The antennae also resemble the same appendages in Cyclopina 

 gracilis; they aie composed of four joints, the penultimate 

 one being the shortest (fig. 3).
