No. 890. (? imm., 23. vi. 06. Soft parts as above. 



All these specimens differ from Para birds {M. h. hellmayri Snethl.) by the 

 presence of a large, concealed white dorsal patch. 



M. hauxwelli is a very near ally of M. guttata, as pointed ont in Nos. Zool. 

 xiii. p. 309, where, however, the differences between the males are not properly 

 stated, for the former species, besides its slate-grey abdomen, is characterised by 

 several other distinctions. The markings on the wings, upper tail -coverts and 

 rectrices are much smaller and pure white (not fulvous as in .1/. guttata), the quills 

 are edged with schistaceous (not with rufescent brown) and the rump is pure 

 slate-grey.

The S belongs to the typical form with slate-grey upper parts and not to the 

 black-backed M. a. melaena (Scl.) of which the Tring Museum possesses specimens 

 from Iquitos, N.E. Peru. The females of the two forms are not distinguishable.

No. 771. <5 ad., 7. vi. 06. " Iris brown, feet bluish black, bill black." — Wing 

 58 ; tail 32J ; bill 14 mm. 



This bird has the belly of the same dark slaty grey colour as a series from 

 Cayenne, but the malar region is paler grey and the ear-coverts narrowly striped 

 with silvery white as in the Para specimens (cfr. Nov. Zool. xiii. p. 369), which, 

 however, have the middle of the abdomen whitish grey. Yet it must be remarked 

 that in a <J from the Catira River, Venezuela, the belly is quite as pale, while others 

 from the same locality do not differ in this respect from the Cayenne skins. More 

 material is required to settle the question whether there are any geographical races 

 of this species or not.

The S 6 ad. differ somewhat inter se in the markings of the tail. One 

 (No. 910) has the rectrices uniform light grey with narrow white apical margins, 

 exactly as the types of M, boliviano, Berl., and the original example of M. menetriesii
