254 The Ottawa Naturalist. [Feb. 



appreciate, but he includes notes on habit, food and distribu- 

 tion. He holds that the salmon feeds in fresh water, and the 

 Ontario Salmo salar must have done so, though the salmon 

 migrating from the sea ceases to feed, there can be no doubt. 

 In British Columbia rivers there is not food for the vast schools 

 of ascending fish, and in all no doubt as spawning time approaches 

 they fast and the stomach is clogged with dense tenacious 

 mucus, a result of a kind of catarrh as described by Dr. Noel 

 Paton in the Scottish salmon, and familiar too in the lake white- 

 fish. Tastes differ and Mr. Nash, in stating that the lake ling 

 or burbot is considered worthless as food, cannot be aware of 

 the opinion of many fishermen that there is no better food fish, 

 the meat being white and of good flavour like the cod or haddock, 

 its nearest relatives. The fall-fish (SemoHlus corporalis) is 

 served up as whitefish at some Ontario Fishing Clubs notwith- 

 standing Mr. Nash's view that as a food fish it does not take 

 high rank. It has good table qualities however. 



It is plain that Mr. Nash's work is full of interest, but 

 fishermen will dispute many points until the end of time. If 

 a second edition is called for, as will certainly soon be the case, 

 the value of the plates would be increased by clearly outlining 

 in each figure the three or four gill-cover elements, and by in- 

 dicating as correctly as possible the exact number of rays in 

 the unpaired fins. The author is to be congratulated on the 

 very few misprints; but on p. 9 Icthyomyzon should be Ichthy- 

 omyzon, on p. 63 Cristimover in two places should be Cristivomer, 

 and on p. 118 saggitaie should be sagittate. The name of the 

 authority should also be appended to each scientific name. 

 Finally, the occurrence of other examples of Polyodon (the 

 paddle fish) in Canada than the two mentioned, was noted in 

 an article in the Ottawa Naturalist in 1899, p. 153, and the 

 addition of an index would be an improvement. It is a most 

 useful, indeed valuable^ and creditable publication, and all 

 interested in Ontario fishes will feel indebted to its author.

PURE WHITE CALYPSO BOREALIS. 



It may be of interest that a pure white Calypso was ob- 

 tained by me at Thetis Lake last spring. I am not aware that 

 such a specimen has previously been reported. I transplanted 

 the bulb with the object of ascertaining whether the habit _ was 

 constant but I fear that the hordes of robins which insisted 

 pon scratching up the moss covering have destroyed the bulb.
