Mr. Allen. The notes of habits, etc., are very valuable and useful, and, 
(its main points, if we recollect rightly, having been already presented in 
the NATURALIST by Mr. Allen), several of the entries are of special inter- 
est and importance. Ano ong these way be mentioned siia Bairdii, 
Argytira maculata (accidental), Xant hal (accidental) 
Tyrannus Weapon n. tal), Paster domestica (introduced), Chon- 
destes grammaca (ac tal), Turdus nevius (accidental), Helmintho- 
phaga per penis an. sacer (unusually southern), Strix pratincola (rarel 
so northe iind Micropalama himantopus (rare), Macrorhamphus scolopa- 
ceus, Thalasseus acuflavidus, Pelecanus trachyrhynchus, and P. fuscus (both 
of these an accidental). 'The first named Mr. Maynard considers as 
more likely to be a winter visitor from p north, than a straggler from 
Nebraska. Quiscalus major, acne Wilsonius, and a few other species 
occurring in Allen's or Coues’ lists, he dismisses as resting upon insuffi- 
cient evidence; probably in most instances he is correct in so doing. The 
supposed Buteo ** Cooperi” turns out to be a state of B. lineatus. A good

We have "un so 6. ponti impressed with the book, and others will 
doubtless find it so useful, that we feel the less hesitation in criticising 
some things in it that we cannot praise. A little care would have pre- 
vented such slips as *'carpel" for carpal (p. 20), ** coccygus " for coccyz, 
or for os coccygis, **arctea" for arctica (p. 152), ** Argyria" for Argytira (p. 
164), ** penguin" for peregrine (p. 184), etc. We fear, however, that the 
ter himself is responsible for such awkward blunders as — ** where the 
humerus joins the sternum" (p. 40); and the mention of the wrists and 
heels of sheep and deer as ** knee ncn " (p.49). The figures we cannot 
speak well of; in fact, they are very bad, and we should judge that "s 
will hardly answer the purpose for which they were designed. Thus 
sistently questioned specific validity: Falco anatum, Astur atricapillus, Pandion Carolinensis, 
Otus Wilson ianus, piae Cassini, Nyctale Richardsoni, There are many others, as nearly
