 Type of Caprimulginse. 



Cranium not so much depressed as in Podargus ; space between the orbits on the 

 upper surface of the cranium very narrow. Maxillaries curved downwards. Palatine 

 bones similar in shape to Podargus ; intermaxillaries not expanded. Tarsi longer in 

 proportion to the tibia than in Podargus. Sternum much damaged, but with two 

 fissures on each side of the keel. Remaining bones as in Podargus.

Virginianus, Briss. 

 Cranium much depressed, and in shape similar to Podargus, but without the tem- 

 poral impressions for the masseter muscles. Maxillaries not expanded over the roof of 

 the mouth, which is merely defended by a narrow strip of the palatine bones carried 

 forwards posteriorly ; the palatine bones are more expanded laterally than in Podargus, 

 and with the angles rounded ; interarticular bones long. Sternum with a single wide 

 and open fissure on each side of the keel. Coracoids, furculum, and scapula similar 



to Podargus.
