thus delayed much beyond the anticipated date when Part II was issued, 

 only a few advance copies in paper covers being distributed during the 

 last days of 1904. It includes about the same number of pages as Part 

 II, and almost exactly the same number of species and subspecies, namely 

 434, as compared with 433 in Part II. As the general character of the 

 work has been indicated in our review of Part I (Auk, XIX, Jan., 1903, 

 pp. 97-102) we have now merely to note the contents of Part III, which 

 includes the following 15 families. 



(1) Motacillidae, with 3 genera and 8 species; (2) Hirundinidae, 12 

 genera and 32 species and subspecies; (3) Ampelidse, 1 genus and 2 spe- 

 cies ; (4) Ptilogonatidse, 3 genera and 5 species; (5) Dulida? (wholly 

 West Indian), 1 genu's and 2 species; (6) Vireonida?, 8 genera and 78 spe- 

 cies and subspecies ; (7) Laniidse, 1 genus and 21 species with 6 additional 

 subspecies; (8) Corvidse, 13 genera and 83 species; (9) Paridse, 4 genera 

 and 36 species and subspecies ; (10) Sittidae, 1 genus and 10 species and 

 subspecies; (11) Certhiida;, 1 genus and 6 subspecies ; (12) Troglodyti- 

 dx, 17 genera and 135 species and subspecies; (13) Cinclidae, 1 genus and 



3 species and subspecies; (14) ChamaMdas, 1 genus and 4 species and 

 subspecies ; (15) Sylviidse, 3 genera and 22 species and subspecies. 

 These statistics include the 5 subspecies added in the Addenda. 



Four genera, 1 species, and 14 subspecies are described as ' new,' 

 mostly in the first half of the volume, but only one appears to have been 

 really new at the time of its publication, the others having been pub- 

 lished elsewhere before the volume was completed, and thus antedate by 

 nearly a year the date of Part III. Their real place of publication, how- 

 ever, is duly stated in the addenda, and attention is called to the fact in 

 the ' Table of Contents.' 



The genus Polioptila, provisionally referred in Part I (pp. 18 and 23) to 

 Mimidge, here finds a resting place in the Svlviidae, forming a subfamily 

 Polioptilinre. The only alternative, Mr. Ridgway believes, is to make the 

 group a separate family. 



To take up the nomenclature of the work somewhat in detail with 

 special reference to the A. O. U. Check-List, it is to be noted that Neororys 

 is considered as not entitled to even subgeneric recognition ; Vireosylva 

 and Lanivireo are given full generic rank; Cractes Billberg ( 1828) is 

 made (in the addenda, p. 750) to replace Perisoreus Bonaparte (1831 ); 

 Penthestes unfortunately has to take the place of Parus, which is 

 restricted to the Old World, with Parus major as the type. On the 

 whole this is a very slight disturbance of our current generic nomen- 

 clature. 



In respect to species and subspecies, the status of a few forms is 

 changed ; a number of forms rejected by the A. O. U. Committee have 

 been admitted, but in most instances its decisions are confirmed. A 

 curious case, however, is that of " Ba?olop/uis atricristatits sennetti, sub- 

 sp. nov.," which takes the place of both Bceolophus bicolor texensis (Sen- 

 nett) and B. atricristatus casta?ieifron$ (Sennett), which are ruled out as
