From the above, it seems that the average dimensions of the 
females do not fall short of those of the males. 
A dozen eggs from San Benedicto Island are white, and vary 
in form from ovate to elongate ovate, and measure in milli- 
meters: 58.4x41.5; 58.7x41; 59.4x38.5; 61x43.5; 61.7x40.6; 
62x42; 62.5x41.5; 64x40.2; 64x42; 64.2x41.5; 64.5x39.3; 
64.5x40.

By far, Buller’s Shearwater is the rarest shearwater in col- 
lections. Dr. Godman reports only six specimens in his mono- 
graph—five from New Zealand and one from California 
waters, the last, a female, shot by myself on the ocean near 
Point Pinos on November 6, 1896. Mr. R. H. Beck has since 
obtained fifteen off Point Pinos, more than doubling the num- 
ber of specimens previously known to science. Unfortunately, 
his first specimen, secured in September, 1903, was destroyed 
in the Conflagration of April, 1906, along with the one cap- 
tured by myself. Of the remaining fourteen, nine were collected 
for the Academy and five for the University of California. 
The University specimens are all males, and were taken in 
1910—one on September 14, three on September 26, and one 
on October 13. The Academy specimens are of both sexes and 
were procured during two autumns, as follows: A female on 
September 2 and two males on November 4, 1907; a male on 
the 9th, a male on the 13th, and two males and two females on 
the 15th of October, 1909. 
The breeding places of this Southern Hemisphere species 
and the route by which it reaches the vicinity of Point Pinos, 
California, are unknown. 
Below are Mr. Beck’s notes for 1907 and 1909. 
1907. In February I returned to Point Pinos to spend a 
year endeavoring to replace in some degree the Academy's 
water bird collection destroyed in the great fire of 1906, giving
