824 PROCEEDINGS OF THE ACADEMY OF 



39. Celeus cinnamomeus, (Linnaeus.) 



Beautiful and very accurate figures of the male and female of this species 

 are given by M. Malherbe, (pi. 56.) Specimens of the young of both sexes 

 are in the Academy Museum, and differ from the adult in the darker color of 

 the crest. In that of the male the color may be said to be a lighter shade of 

 the same cinnamon color of the other plumage, though evidently changing to 

 the dull, yellowish-white of the adult. Vieillot, pi. Ill, Ois. d'Am. Sept., 

 seems to represent the young male. 



40. Celeus mentalis, Cassin. 



Celeus mentalis, Cass. Proc. Acad. Philada., 1860, p. 13. Jour. Acad. 

 Philada., v. pi. 52. fig. 2, 3. 

 This species, and my description of it above cited, were unknown to M. 

 Malherbe. Specimens of both sexes are in a collection made during a survey 

 of the River Atrato in New Grenada, by Lieut. Michler, U. S. Top. Engineers, 

 now in the National Museum, and are represented in the plate of the Journal 

 of the Academy, above cited. 



-11. Mesopicus goertan, (Gmelin.) 



Picus goertan, Gmelin, is a name given to the bird figured in Buff. pi. Enl. 320. 

 This bird is in nearly every collection from the Gambia or Senegal country, and 

 is now a well known African species, presenting some variations of plumage, 

 but is not difficult to distinguish. Generally, specimens have the middle of 

 the abdomen yellow, of darker or lighter shade, but occasionally the same 

 part is crimson, in which plumage it is Dendrobates poicephalus, Swainson, 

 and may be the adult bird. 



Specimens from Fazogloa, Eastern Africa, do not differ materially from 

 those from Gambia. It is an error to regard Dendrobates spodocephalus, Bona- 

 parte, (Z>. poicephalus Riippel, nee Swainson,) as identical with this species. 



42. Mesopicus spodocephalus, (Bonaparte.) 



" Dendrobates poicephalus, Swains." Riipp. Syst. Uebers, p. 86, pi. 34. 



This is an entirely respectable species. Though of similar general appear- 

 ance and distribution of colors, this bird is certainly different from the pre- 

 ceding and resembles, in a greater degree, Mesopicus capensis, (Gmelin.) The 

 head and under parts of the body are clear lead color, much darker than in 

 M. goertan, the tail is clearer brownish-black, the scarlet space on the abdo- 

 men larger, and in other respects it is clearly distinct and easily distinguished 

 on comparison of specimens. 



This bird is accurately figured by M. Riippell, as above cited. One speci- 

 men in the Acad. Mus. is stated to be from M. Ruppell's collection in Abys- 

 sinia. 



43. Mesopicus griseocephalus, (Boddaert.) 

 Picus capensis, Gmelin. 



Very accurate aud handsome figures of the male and female of this species 

 are given by M. Malherbe, (pi. 62, fig. 7, 8, 9,) and it presents much unifor- 

 mity of colors in adult .plumage. The young female of this species is Den- 

 drobates immaculatus, Swainson. The young male is as follows : 



Young ^. Crown and rump scarlet, with a cupreous tinge ; upper parts of 

 body dull olive green, much less yellow than in the adult. Head (except 

 crown) and under parts dull greenish cinereous, tinged with reddish-brown on 

 the sides. The young birds of this species in the Acad. Mus. are from the 

 collection of that excellent ornithologist, M. Jules Verreaux, of Paris. 



44. Mesopicus immaculatus, (Swainson.) 



Dendrobates immaculatus, Swains., B. of W. Afr. 11, p. 152, (1837.) 

 As stated above, this bird is the young female of the preceding, and in my 

 opinion, can be recognised as such on comparison of the description of 

 Swainson with a female specimen, or with a figure of the female.
