Vol. XXII-j Recent Literature. 22 1 



' hybrids 1 between B. atricristatus sennetti and B. bicolor, and are thus 

 "without nomenclatural standing" ! The ' hybrid' theory is not here for 

 the first time invoked by our author as an easy way to clear up a knotty 

 case, as witness his treatment in Part I of Junco annectens Baird, J. ridg 

 ivayi Mearns, etc., and in other instances on earlier occasions. 



Further changes among the Titmice include Bazolophtts inoruatus 

 tnttrinus as a new subspecies from southern California and northern 

 Lower California ; B.ivolliveberi is restricted to the highlands of Mex- 

 ico, and the United States form takes the name B. w. annexns (Cassin). 

 Partis (or Penthestes) carolittensis impiger of Bangs is added, as is also 

 P. hudsonicus liltoralis, while P. h. stoneyi is referred to hudsonicus. 

 Psaltriparus minimus saturates is described as new from the Puget 

 Sound region. 



The range of Corvtis corax clarionensis is extended northward to 

 include the Santa Barbara Islands, and is thus brought within our Check- 

 List limits. • Corvtis brachyrhyttchos hespcrius is revived, and C. caurinits 

 is reduced to a subspecies of C. brachyrhynckos. Cyanocitta stelleri 

 borealis is not recognized while C. ■;. carbonacea is, although the former 

 is quite as good a form as the latter. 



Among the Wrens are many additions of forms recently denied admis- 

 sion to the Check-List, as Telmatodytes paltistris thryophiltts, T/iryomanes 

 bewickii eremophiltis, T. b. cerroettsis, T. b. nesophiltts, T. b. drymcecus, 

 and Catherpes mexicantis polioptilus while, on the other hand, T. leu- 

 cophrys is reduced to a subspecies of T. betvickii, and Troglodytes aedon 

 aztectts is made a synonym of T. a. parkmani and the range of the latter 

 continued eastward to Indiana. Salpittctes obsoletus pulverius is also 

 admitted, and 6\ guadaltipensis is reduced to a subspecies of .S. obsoletus. 



The American Dipper takes the name Cinclus mexicatttis unicolor 

 (Bonap.), typical mexicatttis being restricted to Mexico and Guatemala. 

 All the hitherto described forms of C/tatmva are admitted, and Regulus 

 cuvierii ranks as a good species on the basis of a single record and the 

 "type lost"; in other words, on the description and drawing of a speci- 

 men alleged to have been taken near Philadelphia nearly a century ago. 



The ' Addenda,' as often happens, forms an important part of the 

 volume. It not only contains many overlooked references which are to 

 be added to the tables of synonymy, but many references to publications 

 that appeared during the printing of the volume, and especially after the 

 printing of the first half, among which, as already noted, are references 

 to the publication of the genera and subspecies indicated as new in the 

 main text; and it also includes a number of additional subspecies and 

 changes of nomenclature. Attention is called to most of these, by foot- 

 notes or otherwise, in the table of contents, but the table of contents is 

 not to be taken as giving the nomenclature of the species as finally modi- 

 fied in the addenda ; for there are no footnote references to guide the 

 unwary to such changes as that of Corvtis americanus to Corvtis brachy- 

 rhynckos, or the substitution of Cractes for Perisoreus, as one would 

 naturally expect.
