198 Todd, The Genus Eupsychortyx. IXpril 



the breast, which is fawn color or wood brown at first; centers of the 

 feathers of the sides and flanks tinged with Brussels brown or antique 

 brown. 



Measurements. — Male (ten specimens) wing, 96-106 (average, 102); 

 tail, 57-67 (62); bill, 12-13 (12.7); tarsus, 25-30 (27.5). Female (six 

 specimens); wing, 95-99 (97); tail, 58-62 (60); bill, 12-13 (12.5); tarsus, 

 25-28 (26). 



Range. — From Guiana and extreme northern Brazil to Venezuela (ex- 

 cept the Cariaco Peninsula) and Colombia, east of the Andes. 



Remarks. — The earliest mention of this species which I can 

 trace is that by Pierre Barrere, who refers to it in his work on 

 the natural history of French Guiana, published in 1741. The 

 Abbe Rozier gave a brief and rather unsatisfactory description of 

 it in 1772, but in 1802 a signed article by Virey appeared in Son- 

 nini's edition of Buffon's " Histoire Naturelle de Oiseaux," giving 

 a much fuller account of the bird as observed in French Guiana. 

 It was formally described by Temminck under a binomial name 

 in 1815, from specimens said by him to have been given to the 

 Paris Museum, where presumably they still are. Vieillot, Lat- 

 ham, and the other authors of that time apparently knew the 

 species only from these earlier sources, which they usually quote. 

 Early in 1830 Vigors described a quail from an unknown locality 

 under the name Ortyx affinis, and Gould another from Colombia 

 in 1843 as Ortyx parvicristatus. This brings us down to 1850, the 

 year when Gould's "Monograph of the Odontophorinre" appeared. 

 In this work Gould figured and described both sonnini and parvi- 

 cristatus, referring them to his new genus Eupsychortyx, but did 

 not consider it necessary to figure affinis, regarding it as too close 

 to sonnini. Subsequent authors have accepted both sonnini and 

 parvicristatus mainly on- Gould's authority, as one after another 

 records began to come in from British Guiana, Venezuela, and 

 even as far south as Brazil. All these were duly referred to son- 

 nini (although sometimes with misgivings), except that Cabanis, 

 possibly by inadvertence, confused the British Guiana bird with 

 cristatus. 



It would appear that up to the time of Dr. Chapman's recent 

 explorations in Colombia no specimens from that country with 

 authentic data were available, the alleged species parvicristatus 

 being known only from so-called "Bogota" skins. Indeed, his
