The author estimates the species of birds as positively 

 occurrinji, or having occurred of their own free will, within 

 the limits of his work as 327. Of these only 26 are 

 permanent residents, including 2 introduced species, whereas 

 the summer-visitors are as many as 115, and those occurring 

 chiefly or entirely as transient visitors are 75. The winter- 

 residents and winter- visitants of fairly general or regular 

 occurrence are 40; the accidental visitors or occasional 

 stragglers arc 67; whilst the remaining 4 species included in 

 the list are now extinct. 



Mr. Knight follows the arrangement and nomenclature of 

 the American ' Check-list ' throughout, and quotes its 

 ''number^' at the head of each of his species. After a 

 short description he devotes a few lines to explain its 

 general geographical distribution, and then gives a list of 

 the various exact localities in Maine in which it has been 

 observed, adding carefully the authority for its observation. 

 Full particulars then follow as to its habits, nest, and eggs, 

 and any other point in its history worthy of record. We have, 

 therefore, in Mr. Knight's volume a complete Handbook of the 

 Birds of Maine, amply sufficient for the information of any 

 resident in the State who takes a general interest in the 

 native birds and wishes to determine a doubtful species. 

 We have no doubt that Mr. Knight's work will have a good 

 circulation among the residents in the State of Maine and 

 its vicinity, and will serve to increase their knowledge of 

 the bird-life which surrounds them.

Mr. Lydekker's book being written specially for sportsmen, 

 he has been careful to adapt it to their chief requirements. 

 He tells us that the descriptions have been made simple, but 

 sufficient, and that the records of the occurrences of the rarer 

 species are full and up to date, while short life-histories are 

 added and figures given in every case. We cannot, however,
