-3- 
Audubor^s Shearwater (1 + 1 nocturnal)* 
Very low numbers have been recorded in the grid since September 1965* 
As with the previous species, a few stragglers from the Phoenix group 
probably account for its presence in the grid* 
Juan Fernandez Petrel (1). 
Small numbers were apparently migrating through the grid during 
November-December 1965, but other than this the species has either been 
absent or encountered in very low numbers* 
Pterodroma hypoleuca (1)• 
The single individual was probably a Black-winged Petrel (P. h. 
nigripennls )* These were not encountered during the previous cruise, 
but were present from September-December 1965. 
Bulwer 1 s Petrel (101 + 3 nocturnal). 
Until the present cruise this species has always been recorded in 
low numbers* Five specimens were collected during the present cruise* 
All were at the terminating stages of molt, with flight feathers complete. 
Most sightings were of birds moving in an easterly-southeasterly direction* 
The greatly increased numbers are apparently migrating birds moving to the 
Phoenix or Line Islands* 
Leach*s Storm Petrel (21). 
Unidentified white-rumped storm petrels (172 ♦ 15 nocturnal). 
The 21 Leach 9 s Storm Petrels represent collected specimens* Undoubtedly 
the vast majority of the 187 unidentified birds belong to this species. A 
small percentage of the unidentified birds may be referrable to Wilson f s 
* 
or Harcourt # s Storm Petrels, both of which were collected in the grid 
during fall 1965, Storm petrels were first encountered in the grid area
