 97. Pteroglossus flavirostris mariae Gould. 



[Pteroglossus flavirostris Fraser, P. Z. S. 1S40. p. 61 (ex Gould : P. azarae (nee Vieillot !) Monogr. 

 Rhampli. ed. i. (1834) pi. 17.— no locality).] 



Pteroglossus Marine Gould, Monogr. Shamphasl. ed. 2. pi. 30 (1854. — "the woods clothing the 

 sides of the Lower Amazons, whence many specimens have been sent by Mr. Hawkswell " 

 (sic)— errore ! We substitute Peruvian Amazons as the typical locality). 



No. 452. ? ad., 3. vi. 06. " Iris red, feet blackish grey, bill yellowish white, 

 lower mandible brown." — Wing moulting ; tail 135 ; bill 79A mm. 



The examination of the material in the British Museum, and of the smaller, 

 but much more carefully labelled, series in the Tring collection, convinced me that 

 Gould was perfectly correct in separating P. mariae from typical P. Jlavirostris. 

 Although there is no constant difference in size between the two forms, the coloration 

 of the bill serves to discriminate them at a glance. 



In P.f. flavirostris the lower mandible is yellowish except a narrow elongated 

 patch of ochraceous along the cutting edge, while in P. f. mariae the whole 

 mandible is ochraceous brown. This observation, which is based on a large number 

 of skins, is fully corroborated by the notes made by Messrs. Cherrie, Klages and 

 Hoffmanns from freshly killed birds. In six specimens of P. f. Jlavirostris from 

 the Orinoco and Caura the under mandible is stated to be " pale primrose yellow, 

 with an elongated stripe of ochraceous along the cutting edge," while Mr. Hoffmanns 

 calls the colour of the lower jaw in three specimens of P. f. mariae " light 

 brown." 



The range of the two forms is as follows : 



a. P. f. Jlavirostris Fras. 



South Cayenne : Oyapoc (Verdey) ; Venezuela : Nericngna and Mimduapo, 

 Orinoco (Cherrie), La Vuelta (Klages) and La Pricion (Andre") on the Caura River.

 Rio Javari (Bates) ; Peru : Samiria on the Amazons (Hauxwell), Chuchurras, 

 province of Huanuco (Hoffmanns), etc.
