leg-bones, and the tarsus is at least twice as long as the femur ; 
the basal phalanx of the middle toe is as long as the next two 
joints, or longer than them ; the keel of the sternum has a 
large fenestra”; the tarsi are usually covered in front with 
a single shield, or with transverse short scutes ; the outp and 
middle toes are sub-equal in length, and the secondaries are 
ten in number. (Cf. Salvin, Cat. Birds Brit. Mus. xxv. p. 343-)

Type, O. oceankus (Kuhl). 
Two species of the genus Oceaniies are known, viz., O. 
oceankus, which inhabits the Atlantic, Indian, and Australian 
Oceans, and 0 . gracilis (Elliot), which is found along the 
western coast of South America. 
In Oceaniies the claws are not so much flattened as m 
Pelagodroma and the other genera of the sub-family, arid the 
basal phalanx of the middle toe is normal or only slightly 
flattened, less so than the remaining joints and claws, the 
latter being sharp and spatulate. The scutellie of the front 
of the tarsus are obsolete, a character distinguishing Oceaniies 
from Garrodia, an allied genus with a single species, G. nereis, 
peculiar to the southern Oceans.
