have been positively known to occur in the Province of Ontario. In 

 cases where I have no personal knowledge of the record I have given the 

 authority for it." The nomenclature and numeration are those of the A. O. 

 U. Check List. The numeration is therefore not consecutive, nor is the 

 whole number of species and subspecies stated. They number, by count, 

 324; with the House Sparrow, 325 — about 8 more than were given by 

 Mcllwraith in 1894. The species are concisely annotated with reference 

 to their season of occurrence, relative abundance, breeding ranges, dates 

 of migration, etc., while special stress is often laid upon their economic 

 relations, as to whether beneficial or injurious and how. A paragraph is 

 also given to the principal diagnostic characters of each of the orders and 

 families, with an illustration representing some species of each family. —

'An Ecological Survey in Northern Michigan.' ' — This Report gives 

 the results of a natural history survey of the Porcupine Mountains and 

 Isle Royal, in the Upper Peninsula of Michigan, made by a party from the 

 University Museum, Michigan University, during the summer of 1904. 

 The field party consisted of N. A. Wood (in charge), assisted by A. G. 

 Ruthven, and Otto McCreary, N. F. Macduff, Max M. Peat, and W. A. 

 Maclean, acting under the direction of Prof. C. C. Adams, curator of the 

 University Museum. In an introductory note Prof. Adams describes the 

 purposes and methods of the survey, and the results are embodied in a 

 series of papers by the different members of the expedition. The orni- 

 thological parts of the Report are: 'The Ecological Distribution of the 

 Birds in the Porcupine Mountains, Michigan ' (pp. 56-67), by Otto McCreary, 

 in which the physical characteristics of the 'stations' and 'substations' 

 are described, with a separate enumeration of the birds found at each; 

 and 'Annotated List of the Birds of the Porcupine Mountains and Isle 

 Royal, Michigan' (pp. 113-127), by N. A. Wood, Max A. Peet, and O. 

 McCreary. The observations in the Porcupine Mountains covered the 

 period July 13 to August 13; number of species listed, 89. The Isle Royal 

 observations were made from August 16 to September 5; number of species 

 listed, 81. There are lists also of the plants, insects, mollusks, fish, amphi- 

 bians, and mammals, the latter by Professor Adams, on the basis of the 

 specimens and notes obtained by the different members of the expedition. 



The work here undertaken is of an excellent character, and forms a 

 good beginning, but nothing very conclusive can be expected from such a 

 brief period of observation, and, as respects birds, conducted at a season 

 of the year when they have for the most part concluded their home duties 

 and are either given to wandering or are in actual migration. — J. A. A.
