236 / MESSRS, SCLATER AND SALVIN ON [ Mar. 16, 
Hab. Upper wood-region of the Paramo de la Culata, Merida 
( Goering). 
Obs. Assimilis B. schistaceo, sed pileo clarius castaneo in frontem 
producto, loris non albis et speculo alari nullo distinguendus. 
Mr. Goering sends two additional examples of this species, which 
in our previous paper we did not distinguish from B. schistaceus of 
Columbia and Ecuador. It appears, however, to be fairly separable. 
In Peru, again, we find another representative species of this 
section of the Buarremones, the B. mystacalis of Taczanowski 
(P. Z.S. 1874, p. 515). In this form there is likewise no white 
speculum on the wing ; but the white lores are very distinct, and the 
chestnut cap is lighter than even in B. castaneiceps. Unfortunately 
the term mystacalis has already been used for a nearly allied 
species of Buarremont, so that we propose to alter the name of the 
Peruvian form to B. taczanowskii. Of this bird a figure (Plate 
XXXV. fig. 2) is also given, for comparison with the allied Venezuelan 
species. 
*36. AULACORHAMPHUS CALORHYNCHUS, Gould, Ann. N. H. 
ser. 4, vol. xiv. p. 183 (1874). 
Mr. Gould’s description of this bird was based on examples 
obtained at Merida by Mr. Goering during his late expedition. 
We agree with Mr. Gould in regarding this as a new species allied 
to A. sulcatus, but easily distinguishable by the yellow upper man- 
dible. Judging from our specimens of A. sulcatus, however, it is 
not larger, but rather smaller than that species. 
Besides A. calorhynchus, Mr. Goering obtained, on his second 
journey, a single specimen of an Aulacorhamphus which Mr. Gould 
(J. s.c. p. 184) has referred to his newly described A. pheolemus. 
After examining this specimen (in Mr. Gould’s collection), also a 
more adult example of the same bird obtained by Mr. Goering on 
his first expedition to Merida, and now in Salvin and Godman’s 
collectiont, and comparing it with several ‘‘ Bogota” skins (true 
A. albivitta) and skins obtained by Mr. Salmon in the province 
of Antioquia (types of Mr. Gould’s 4. pheolemus), we have come 
to the conclusion that A. pheolemus is not, in our opinion, fairly 
separable from A. albivitta. In one of Mr. Salmon’s skins (in Mus. 
S.-G.), and in the adult skin obtained by Mr. Goering on his first 
expedition, the throat is quite as white as in ordinary “ Bogota” 
skins of A. albivitta. 
We may add that Mr. Goering’s specimen of Aulacorhamphus, 
obtained at Caripé, which was determined by us (P.Z.S. 1868, 
p- 169) as d. sulcatus, is Mr. Gould’s A. erythrognathus (I. s. c. 
p- 184), but that Mr. Goering has also sent home the true 4. sul- 
catus from 8. Esteban (cf. P. Z.S. 1868, p.629). The distinction 
between these two nearly allied forms, though slight, appears to be 
valid.
