are arranged alphabetically, the papers of each author following the sketch 

 in chronological order. The amount of data that the authors have gath- 

 ered together is enormous, and historians and biogi-aphers in general will 

 find this work a veritable mine of information. Ornithologists are seldom 

 narrow, and we find that most of the authors here enumerated were noted 

 in other fields as well. William Bullock whose name is ever associated 

 with the early collections of Mexican birds, is listed as a ' naturalist, col- 

 lector, traveller, antiquary, auctioneer and showman ' while he describes 

 himself on the cover of his ' Museum Companion ' as ' Silver-Smith, 

 Jeweller, Toyman and Statue Figure Manufacturer.'! 



In addition to the account of Bullock, American ornithologists will find 

 facts of interest in the sketch of Capt. Thomas Brown, publisher of the 

 ' Illustrations of American Ornithology,' and ' Game Birds of North Amer- 

 ica,' two of the rarest of American ornithological works, while the biog- 

 raphers of Thomas Bewick and Daines Barrington will attract many. We 

 shall look with interest for the succeeding parts of this important work, — 

 a work that should be in all reference libraries. — W. S. 



Todd on Dysithamnus mentalis.^ — In this paper Mr. Todd has 

 presented a painstaking monogi-aph of a difficult genus of Formicariidge 

 including detailed descriptions, full synonymy, maps showing the dis- 

 tribution of the species, lists of specimens, and extracts from hterature 

 relating to habits, etc. In all respects this is a model piece of work and one 

 which could well be followed by other writers. Five species of the genus 

 are recognized: D. mentalis (divided into five races), semicinereus, extremus, 

 affinis (three races) and andrei. The new forms are D. m. cequatorialis 

 (p. 539), Zaruma, Ecuador, D. m. lateralis (p. 540), Guarico, Venezuela; 

 and D. extremus (p. 549), Cauca, Colombia. — W. S. 



Cherrie on New Neotropical Birds.- — Mr. Cherrie describes ten 

 new South American birds from the collections of the American ]VIuseum 

 of Natural History. Two of these were secured by S. M. Klages in Vene- 

 zuela: Hemithraupes flavicollis aurigularis (p. 389), Suapure; and Argicus 

 macrodactylus caurensis (p. 389), La Union. One was obtained in the 

 Orinoco Delta by Dr. Rusby: Piaya rutila orinocensis (p. 393); while the 

 rest were all collected by Mr. Cherrie himself on the Collins-Day Expedi- 

 tion, viz.: Xiphorhynchus gutla'a rimarum (p. 391), Rio Espirito SantO; 

 Bolivia, Taraba major virgidtorum (p. 391), Capito auratus vnsperatus (p. 

 391), Piaya rutila chaparensis (p. 392), and Hypocnemis collinsi (p. 395), 

 all from Todos Santos, Bolivia; Drymophila phantatis (p. 396), Cocha-
