Agreeing in size with <a series from Cayenne, Surinam, Trinidad, etc. 

 The southern form, N. a. derbyanus Gould, is larger, especially the tail much 

 longer, and the nppei parts of a much clearer, paler brown.

Specimens from the Rupuunni River, British Guiana, differ by the much paler, 

 yellowish or yellowish white (instead of deep golden yellow) ground-colour of the 

 lower parts. Additional material is required to show whether the Guiauan birds 

 are separable.

These birds seem to belong to C. p. guttatus. The ? ad. agrees perfectly with 

 the characters given by me I.e., while the 2 3 <3 have the back dull greenish 

 (instead of golden yellow), hence more like Bogota skins. The latter, however, 

 differ by having the rnmp much brighter yellow and more coarsely spotted with 

 black, and the belly is also of a clearer, brighter yellow. C. speciosus Malh., based 

 upon a specimen from the Peruvian Amazons, is perhaps identical with guttatus of 

 Spix. If such be the case, the Bogota form would probably require a new name. 



89. Melanerpes cruentatus (Bodd.) 



Picas cruentatus Boddaert, Tab!. PI. ail. p. 43 (1783. — ex Daubenton, PI. en!. 694, fig. 2. — Cayenne).

 feet grey or black, bill black." 



All five specimens are typical .1/. cruentatus with broad superciliaries, creamy 

 above the eye and golden yellow in the posterior portion. 



9ti. Celeus jumana (Spix).

No. 685. (?) ad., 21. v. 00. "Iris red, feet black, bill pale grey."— Wing 

 153; tail 103; bill 29£ mm. 



The inner webs of the quills are regularly and broadly barred with blackish 

 grey and pale yellow, as in specimens from Para, Santarem, and the Orinoco region. 

 Both the ? from Teffd ami the $ from Itaituba, Santarem (see supra, p. 25) have 

 the upper tail-coverts bright rufous brown, while they are yellow with pale rufous 

 brown edges in a series from Para. ' . citreopygius Sri. & Salv. of Eastern Ecuador 

 and Peru has also rufous brown upper tail-coverts, but differs at a glance by the 

 uniform isabelline rufous inner webs of the remiges.
