X Mallard, but had noticed that in colour, at all events, 

 the hybrids were remarkably like the Mallard. As regards 

 the example of the Gadwall X Mallard, apart from the red 

 cheeks which Mr. Millais had pointed out, it was of interest to 

 note that the position of the white ring of the Mallard was 

 clearly marked in this specimen by one of a metallic green. 



Mr. C. E. Hellmayr exhibited examples of two new 

 species of Neotropical birds, which he described as follows : — 



Tanagrella velia signata, n. subsp. 



Similar to T. velia iridina (Hartl.), which it resembles 

 in the purple-blue colour on the sides of the head and on the 

 margins of the wing- and tail-feathers, but it is at once dis- 

 tinguished by having a distinct ochreous-silvery spot on the 

 anterior part of the crown, just behind the purple-blue fore- 

 head. In this character it agrees with T. cyanomelcena (Wied) 

 from S.E. Brazil, which, however, differs in having the 

 underparts bluish-grey. 



Wing 70, tail 50, tarsus 16, bill 11 mm. 



Type in Tring Museum: $ ad. Para, N.E. Brazil; col- 

 lected by Prof. Steere. 



A female obtained by the same collector resembles the 

 male, but has the spot on the crown a little more mixed with 

 ochreous. 



TODIROSTRUM FUMIFRONS PENARDI, 11. Subsp. 



Similar to T.fumifrons, Hartl., from Bahia, but differs in the 

 following particulars : — the back is pure green (not yellowish- 

 or brownish-green), and the crown shows no trace of the 

 brownish suffusion so conspicuous in the typical form ; the 

 yellowish tips to the upper wing-coverts are decidedly smaller 

 and paler, and the cheeks and ear-coverts pale brownish-grey 

 (not isabclline), only the lores being pale yellowish-buff. 



Wing 44, tail 33^, tarsus 18, bill 13£ mm. 



Type in Tring Museum: ? ad. Near Paramaribo, Surinam, 

 March 3rd, 1905 ; collected by Mr. Chunkoo. No. S. 56. 



This is evidently the northern representative of T. fumi-
