BIRD LIFE IN THE URUBAMBA VALLEY OF PERU. 43 



(23) CRYPTURUS SOUI, subspecies. 



Two males from the Rio Comberciato and a female from the Rio 

 Cosireni represent an apparently undescribed race of this widely dis- 

 tributed and variable species. This material is not, however, 

 in my opinion, sufficient to define satisfactorily the status . and 

 relationships of a Peruvian form, and rather than add to the con- 

 fusion which already exists in this group I prefer to await the receipt 

 of additional specimens before presenting my conclusions in this 

 connection. Meanwhile it may be said that the males, one of which 

 (Sept. 13) is marked as " breeding" are much grayer, less fulvous below 

 than the males of any race known to me, while the female (Sept. 

 11) which is also marked as breeding, resembles in general coloration 

 males from the island of Trinidad, but has the lower tail-coverts 

 more rufous.

(26) CRYPTURUS PARVIROSTRIS Wagler. 



Crypturus parvlrostris Wagler, Syst. Av. Gen. Cryptums, sp. 13, 1827 (Brazil). — 

 Berlepsch and Stolzmann, Ornia, 1906, p. 101 (Santa Ana). 



A female collected by Cherrie at Santa Ana compared with three 

 males from Chapada, Matto Grosso, is darker above with the crown 

 slaty, rather than brownish, and the underparts decidedly more 

 slaty. These differences may be in part sexual but are doubtless 

 also in part racial. 



Brabourne and Chubb ^* have proposed to place this species and 

 0. tataupa in a new genus for which they propose the name Cryp- 

 tureUus. Later ^° Chubb, discovering that this name was preoccu- 

 pied, replaced it with Microcrypturus ; but in 1919, Ibis, p. 10, he 

 continued to use Cnjpturellus. The characters ascribed to the new 

 genus, however, seem at the best to be of not more than subgeneric 

 value and in my opinion the species mentioned may be retained in the 

 genus Crypturus.

(49) NOTHOPROCTA FULVESCENS Berlepsch. 



Nothoprocta fulvescens Berlepsch Proc. 5th Int. Zool. Cong., 1902, p. 548 (Urcos, 

 3500 m., Dept. Cuzco, Peru). 



I refer to this species, of which I have seen only the original de- 

 scription, two not fully mature specimens collected by Heller at 

 OUantaytambo, They have the flanks and abdominal region ful- 

 vous, as in N. curvirostris, but the secondaries are barred with rich 

 fulvous, not with ferruginous as in that species, N. perdicaria, and 

 N. coquimbae.
