scarcely covered by skin, etc., but these features apply to 

 manv other genera. Most of the existing works on American 

 fishes have this grave fault that the descriptions of genera and 

 species are overloaded with details not sufficiently diagnostic 

 and of no aid in distinguishing a fish from its allies. They might 

 as well include the further information that each respective 

 genus and species is "permanently aquatic in habit." Now for 

 one or two detailed suggestions. In the general definition of 

 the Pisces (p. 7) the word "vertical" should be added to describe 

 the plane in which the unpaired dorsal and anal fins stand. 

 "The median line of the body with one or more fins" is not suf- 

 ficient. The fine old Canadian name "Maskinonge" should have 

 been used in this book rather than the United States Mascalonge, 

 which is a non-descript term invented by tourist anglers who 

 were ignorant of the origin of the word "Maskinonge" a 

 voyagetir's form of the Indian Mas, "great," and Kenosha, 

 "fish." Hence the short form "lunge" is wholly misleading and 

 arose from confusion with the French term for the great lake 

 trout, viz., lunge (i.e. 'longe,' the long fish). As to the Gizzard 

 Shad (Dorosoma), which Mr. Nash states has worked its way 

 into Ontario from the Ohio and Mississippi valleys, through the 

 canals, it is a native Canadian fish, and was recorded by the 

 late Edward Jack on the St. John River, at Fredericton, N.B., 

 and no doubt occurs in the St. Lawrence and doubtless also in 

 the Ottawa River, where it appears to be called "whitefish" and 

 is caught by anglers at the foot of the Chaudiere Falls. The 

 Mooneye {Hiodon) also occurs in the Ottawa River, and ranges, 

 as Mr.' Nash states, from the St. Lawrence to Lake Superior. 

 The author speaks of the Green Pike {Lucius reticulatus) as not 

 apparently common; but probably more widespread than 

 appears. This prettily marked species is found as far east 

 as the Kennebeccasis River, N.B., and is scattered generally 

 over eastern Canada. 



The omission of some interesting species is to be regretted 

 (such as Dr. H. M. Smith's Coregonus osmerijormis), especially 

 as an introduced Pacific species, the Steelhead is described (p. 

 63) and twenty pounds specified as its maximum size. Jordan 

 and Evermann name that weight, but specimens are plentiful 

 in the Eraser River of twenty-seven up to thirty-six pounds 

 weight . 



The book is a catalogue of specimens in the Biological 

 Section of the Provinical Museum and this limitation accounts 

 for the exclusion of many species that should be fotmd in a 

 list of fishes of Ontario. Mr. Nash has found space not only for 

 much faunistic information which the working naturalist will
