Cyclops rubellus, Lilljehorg. 



To the Editors of the ' Annals and Magazine of Natural History.' 



Gentlemen, — On 2nd May, 1901, my father and I found in 

 Loughrigg Tarn, near Windermere, several specimens of a small 

 Cyclops which, though closely resembling both C. hicolor and 

 C. varicans, differed from both in certain well-marked particulars. 

 "We found ourselves unable to refer our specimens to any known 

 British species ; but when Professor Lilljeborg's work on the Swedish 

 Cladocera was pubhshed and came into our possession, we were able 

 at once to identify them with C. rubellus, which is intermediate 

 between the two above-named species. We wrote to Professor Lillje- 

 horg on the subject, and he kindly sent us specimens to compare 

 with our own, thereby enabling us to put the identity of our British 

 specimens beyond question. We have therefore to add the name of 

 Cyclops rubellus, Lilljeborg, to the list of the British Entomostraca. 



The following is abridged from our translation of Professor Lillje- 

 borg's description, which he has kindly revised : — 



"The female varies from '6 to -9 niillim. in length. It appears 

 somewhat thick-set, having an ovate, moderately broad eephalo- 

 thorax, though the abdomen is comparatively slender. The first 

 thoracic segment is longer than the abdomen without the apical 

 bristles. The fifth thoracic segment bears on each side a rather 

 large bristle, directed backwards. The abdomen is slightly moie 

 than half the length of the cephalothoras, and its first segment is 

 equal to the three following taken together. The stylets are short 

 and broad, set closely together, and very slightly divergent. Their 

 length is about equal to the distance between the hinder margin of 

 the last abdominal segment and the middle of the last segment but 

 one. The bristle on the outer margin of each stylet is small and is 

 situated about three quarters of the way down. The outermost 

 apical bristle is moderately stout, and shoiter than the innermost
