it is high, with its culmen depressed, the crown feathered, and the 
nostrils bare—the last two characters separating the Penelopinz 
from the Oreophasine, which form the third subfamily of the 
Cracidx,' a Family belonging to that taxonomer’s division Peristero- 
podes? of the group ALECTOROMORPH. 
The Penelopine have been separated into seven genera, of which 
Penelope and Ortalis (erroneously Ortalida), containing respectively 
about sixteen and nineteen species, are the largest, the others 
numbering from one to three only. Into their minute differences 
it would be useless to enter; nearly all have the throat bare of 
feathers, and from that of many of them hangs a wattle; but one 
form, Chamezxpetes, has neither of these features, and Stegnolema, 
though wattled, has the throat clothed. With few exceptions the 
Guans are confined to the South American continent ; one species 
of Penelope is, however, found in Mexico and at Mazatlan, Pipile 
cumanensis inhabits Trinidad as well as the mainland, while three 
species of Ortalis occur in Mexico or Texas, and one, which is also 
common to Venezuela, in Tobago. Like Curassows, Guans are in 
great measure of arboreal habit. They also readily become tame, 
but all attempts to domesticate them in the full sense of the word 
have wholly failed, and the cases in which they have even been 
induced to breed and the young have been reared in confinement 
are very few.? Yet it would seem that Guans and Curassows will 
interbreed with poultry (Jdis, 1866, p. 24; Bull. Soc. Invp. @ Acclim- 
atation, 1868, p. 559; 1869, p. 357), and there is the more 
extraordinary statement that in Texas the hybrids between the 
Chiacalacca, Ortalis vetula, and the domestic Fowl are asserted to be 
far superior to ordinary Game-cocks for fighting purposes. More 
information on this subject is very desirable. 
GUILLEMOT (French, Guillemot*), the name accepted by 
1 See the Synopsis, extensively laid under contribution for this article, by 
Messrs. Sclater and Salvin (Proc. Zool. Soc. 1870, pp. 504-544), while further 
information on the Cracinzx has since been given by the former of those gentle- 
men (7’rans. Zool. Soc. ix. pp. 273-288, pls. xl.-liii.) Some additions have since 
been made to the knowledge of the Family, but none of very great importance. 
2 It would be here out of place to dwell upon the important bearings on the 
question of GEOGRAPHICAL DISTRIBUTION (p. 313) which the establishment of this 
division has tended to shew. For this reference must be made to Prof. Huxley’s 
original paper (wt supra), or to the epitome of it given in the Zoological Record 
(v. pp. 34 and 99). 
3 Cf. E. S. Dixon (The Dovecote and the Aviary, pp. 223-273. London : 1851), 
who argues that the reported success of the Dutch towards the end of the last 
century in domesticating these birds was an exaggeration or altogether a mistake. 
His two chapters are well worth reading. 
4 The word, however, seems to be cognate with or derived from the Welsh 
and Manx Guillem, or Gwilym as Pennant spellsit. The association may have 
no real meaning, but one cannot help comparing the resemblance between the
