Uncirostrum d'orbignyi Boiss (Rev. Zool., 1840, p. 5) synonymized by 

 Sclater (Cat. B. M. XI, 4) with Diglossa sittoides auct. (= D. s. similis) is 

 evidently too large (length 120, bill, 8 mm.) to be referred to that species.

(4029) Diglossa gloriosissima Chapm. 



Diglossa gloriosissima Chapm., Bull. A. M. N. H., XXXI, 1912, p. 166 (Andes w. 

 of Popayan, 10,340 ft.). 



Char. sp. — Most closely related to Diglossa gloriosa Scl. & Salv., but much 

 larger, black areas less sooty, lesser wing-coverts and rump bluer, rufous of under- 

 parts brighter, thighs black, no supercihary line. 



Known, only from the Temperate Zone of the Western Andes. Since 

 its discovery by Richardson and Miller on the Andes west of Popayan, 

 Miller and Boyle secured a beautifully prepared series of this interesting 

 species at the northern end of the same range. Though quite distinct this 

 form is obviously a representative of D. gloriosa of the Venezuelan Andes. 

 It is surprising therefore that neither species has been recorded from the 

 region between Merida and the Andes west of Popayan.

(4030) Diglossa brunneiventris Lafr. 



Diglossa brunneiventris Lafr., Rev. Zool., 1846, p. 318 (Peru); Scl. & Salv., 

 P. Z. S., 1879, p. 496 (Sta. Elena). 



Miller and Boyle secured a large series of this species in the Temperate 

 Zone at the northern end of the Western Andes. It appears to have been 

 hitherto known in Colombia only from Salmon's records for Sta. Elena and
