80 BULLETIN : MUSEUM OF COMPARATIVE ZOOLOGY. 
Cracine and Galline are herein used as short equivalents for “ peristero- 
podous ” and “ alectoropodous,” — the latter terms, although expressing 
the precise meaning needed, being a trifle cumbersome for ordinary use ; 
“galliform” is employed to designate such characters as are shared in 
common by all members of the Galliformes. 
Head. — The beak much resembles that of Ortalis, being moderate in 
size, stouter than in Crax, Rollulus, and Phasianus ; but not so short, 
stout, and decurved as in Colinus and allied genera. The holorhinal 
narial opening is also much like that of Ortalis, and the nasal, which has 
escaped injury, is typically galliform ; the superior process can be clearly 
seen, but the inferior process is covered on its lower part by crushed bone. 
The lachrymal, or prefrontal, appears to have been well developed, con- 
trasting in this respect with the American grouse (in which the prefron- 
tal is usually quite small), and agreeing with the curassows. The post- 
frontal process is stout and directed forwards. The mandible is stout 
and imperforate, and while it has a blunt angular projection, the re- 
curved process so characteristic of the Galliformes is lacking. This is 
the most notable departure from the galliform structure found in the 
skeleton. 
Vertebre and Ribs. — Little can be said of the vertebre save that the 
vertebral column presents the customary galliform arrangement of a free 
vertebra in front of the synsacrum preceded by a mass of anchylosed 
vertebre, but as to the number of the latter nothing can be affirmed. 
The cervicals have suffered from the mistaken zeal of the preparator, 
and but five can be definitely distinguished between what should be the 
axis and where the column disappears in the flattened bones of the 
wings. The caudals are mostly lacking, so that, unfortunately, nothing 
can be learned from them. 
Four pairs of ribs are articulated with the sternum, and at least one 
pair (one is the customary number in the Galliformes) arose from the 
synsacrum. Several ribs lie over the synsacrum, but there is no reason 
to suppose that all of them articulated with it. The usual number of 
ribs among the Galliformes is five on a side; Pavo has six, but the 
number in the present specimen cannot be made out. There is quite a 
little space between the first and second costal facets, the succeeding 
three being crowded together. This is interesting from the fact that it 
is a feature of modern galline birds, the spacing of the costals being 
more regular among the curassows. 
Shoulder Girdle. — The scapula is not unlike that of Rollulus, being 
long, narrow, and with parallel borders, as in many of the curassows, or
