all necessary particulars concerning their prevalence and 
distribution in the different parts of Maine. 
The author estimates the species of birds as positively 
occurring, 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 are 67; whilst the remaining 4 species included in 
the list are now extinct. 
Mr. Knight follows the arrangement and nomenclature of 
the American f 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 
tjie 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,
