Pterodroma jugabilis (Oahu petrel)
Taxonomy
Pterodroma jugabilis was named by Olson and James (1991). Its type specimen is USNM 395173, a partial skull (cranium lacking rostrum and all palatal elements), and it is a 3D body fossil. Its type locality is Barbers Point, Oahu, which is in a Pleistocene reef, buildup or bioherm limestone in the Waimanalo Formation of Hawaii.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. L. Olson and H. F. James 1991 | A very small species of Pterodroma, skeletal elements always more
gracile than in congeners of comparable size when overlap occurs in length; larger than Bulweria bulwerii. Cranium in dorsal view slender and elongate, very dis- tinctive in having the supraorbital impressions for the salt glands nearly contig- uous, separated only by a narrow ridge; postorbital processes reduced (Fig. 2A). Compared with P. hypoleuca: rostrum shorter, with tip not as strongly hooked; humerus much more gracile, bicipital crest not as pronounced, ventral tuberosity in ventral view shorter, ectepicondylar spur more slender and markedly more distally situated, brachial depression smaller and not extending as far proximally; ulna, radius, and major hindlimb elements much more gracile, and the trochleae of the tarsometatarsus markedly smaller and narrower. |
