recorded on 13 September. Only those individuals which were in close range 
could be positibely identified to this race. A total of l8 individuals could 
not be identified as to race. One specimen was collected.

All except one individual were recorded between Oahu and 5 N, although none 
of these was recorded in close proximity to Oahu. This scarcity near the 
Hawaiians was evident during August 1965 . The complete lack of this species 
south of 5-6°N during the entire cruise is most striking. Six specimens were 
collected. 
Bonin Island Petrel a = 0 b = 0 c = 4 
Black-winged Petrel a = 69 b = 15 c = 229 
Pterodroma hypoleuca (unidentified to race) a = 40 b = 0 c = 41 
Greatest numbers of Black-winged Petrels were found north of 2 S ; although 
sporadic sightings occurred through most of the southern area. Quite likely 
most of the birds not identified to race are referable to this form. On the 
final portion of the cruise from Christmas Island to Oahu, a preponderance of 
Black-winged Petrels were headed in a southerly or southwesterly direction, 
often in strong direct flight as if migrating. Two specimens were collected. 
Gould 1 s Petrel a = 9 b = 10 c - 0 
Six birds were noted on 1^ September at 5°N. All others were recorded south 
of the equator, six of them on 12 October, one day north of Samoa. No specimens 
were collected. 
Phoenix Island Petrel a = 0 b = 2 c=6l 
Nearly all sightings were in the vicinity of Christmas Island where large 
numbers of this species breed. One specimen was collected at approximately 7 hi 
This apparently represents the first at-sea collected speciment. 
Mottled Petrel a = 0 b = 57 c=82 
Only one bird was seen during the first half of the trip from Oahu to American 
Samoa. A large number (52) was observed on 12 October north of Samoa, and sight-
