Mar.-Gil.-At Sea 
HARCOURT'S STORM PETREL 
A total of 52 birds were identified as this species, all south of 5°N 
and west of l80°W. They possessed much more white on the rump and tail than 
b “ e similar Leach's Storm Petrel and the tails were noticably straight across. 
An additional 12 were seen November 15 between Makin and Maiana Atolls, 
u-ilberu Islands. This was the only occurrence of this species among the 
Marshall and Gilbert Islands. 
SOOTY STORM PETREL 
Three all dark storm petrels believed to be this species were found 
i^ovemDer 21. Five others had also been seen previously, four of them on 
November 15 in company with Harcourts' Storm Petrels and one between Maiana 
and Kuria Atolls. The occurrence of these storm-petrels in this area seems 
very unusual since they are not recorded from any islands of the Gilberts, 
I ' 
Marshalls or Phoenix. 
LEACH'S STOPM PETREL 
Only one recorded in October, within 250 miles of Oahu, but k8 were seen 
m November wioh the majority (57) on November 26 and 27* A sharp dividing 
line was observed between this species and the similar Harcourts' Storm Petrel 
at 5°N. 
Three specimens collected, two of which flew aboard at night. 
BULWER’S PETREL 
Nearly equal numbers were seen both months (5 and 7) but none were found 
north of 7° in November, in contrast to their nearly random occurrence the 
month before.
