Adult. Similar iu culonitiou to B. m. maculatus ((Jm.), from Bahia and 

 Sautarem, having the breast and sides covered with coarse, rounded or heart- 

 shaped spots of black, but differs at a glance by its shorter tail, and particularly 

 by its much shorter and slenderer bill. Lower throat and foreueck deep tawny- 

 ochraceous, as in B. m. maculatus.

Measurements of B. m. maculatus (Gm.). 



Sixteen adult birds from Bahia.— Wing 77—80 ; tail 72— 76^ ; bill 32A— 

 36 mm. 



Two adult iS, Santarem (Natterer coll.).— Wing 76, 77; tail 71, 72 ; bill 

 35, 36i mm. 



The skins from Sautarem agree fully with our large series from Bahia, and 

 unquestionably belong to the large-billed, typical form. 



B. m. striatipectus Scl. * may readily be distinguished from both B. m. 

 maculatus and B. m. parvirostris by having narrow longitudinal streaks of black 

 on the chest aud sides of the belly. Three examples from Mattogrosso (CnyabA, 

 Retiro, t'aivara) iu the Vienna Museum, obtained by the late Dr. Natterer, have 

 the short tail of B. m. parrirostris ; but the bill, while of the same length, 

 is rather stouter, and the markings on the breast and sides are intermediate in 

 shape, being neither cordiform as in B. m. parvirostris, nor longitudinally streaked 

 as iu B. m. striatipectus, but distinctly oval or " rhomboid." A better series 

 from Mattogrosso is required to show if these characters are constant. 



In B. m. striatipectus >Scl., of which I have examined a large series from 



Eastern Bolivia and Western Argentine (Salta, Tucnman), the tail is always 



considerably longer than in the Goyaz and Mattogrosso birds, varying from 



72 to 80 mm., and the lower throat and foreueck are of a paler ochraceous 



colour.
