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. 
The specimens are all of them small, the largest measuring 7 cm. “Ground 
colour yellowish, setnipellucid, with numerous small dark spots.”
