Momorvs, by R. Gray. 
Ciquinoctialis, Gould. 
When the first part of this work was published I had some fragments of the skeleton 
of Momotus (pl. 12, fig. 13) taken from a skin. I have since obtained a perfect 
skeleton of Momotus C&quinoctialis, which I now figure. 
Cranium rounded, with a rounded projection on side of the vertex. Orbital septum 
entire. Occipital ridge distinctly marked ; impression of the masseter muscles 
distinct; nostrils large, oval. Palatine bones broad, united posteriorly, the central 
edge turned downwards, the exterior edge slightly so. The two plates united for about 
one-third of their length, then narrowed and divaricating and carried forward as two 
strips of bone. 
Sternum broad, with two large fissures on each side of the posterior margin, the inner 
one smallest. Keel deep, arched on its inferior edge’ © Manubrial process broad at 
the base, of moderate length. | 
Pelvis very broad in proportion to its length. The ischiadic foramen large, oval. 
The obturator of moderate size. 
Ribs broadest near their dorsal extremities, and gradually diminishing to their 
junction with the sternal ribs, which are flattened. 
Furculum arched in front, the rami flattened, without any process at their junction. 
Coracoids long. : 
Scapule very slightly bent, pointed at the extremities. 
Wing bones long; the ulna longer than the humerus. 
Leg bones of moderate length.
