From a comparison of these measurements becomes apparent that the only 

 differences worth mentioning consist therein that the Haplochiton has a somewhat 

 shorter mandible, a slenderer caudal peduncle and its dorsal fin in a more posterior 

 situation, while the other proportions are practically identical with those of the charr 

 from Northern Sweden, or at least so similar in both that they can be regarded as 

 lying within the limits of a reasonable variation for a single species. 



14. Galaxias attenuatus (JENYNS). 



Numerous specimens collected just above the mouth of a fresh-water rivulet, 

 Port Albemarle, West Falkland. 9th of September 1902.
