Vou. II, Pr. IT] LOOMIS—A REVIEW OF THE TUBINARES 149 
Pileum and anterior part of cervix deep, or dark, mouse 
gray, forming a cap contrasting with the adjacent upper parts; 
lores and auriculars mouse gray, chiefly dark in tone, inter- 
rupted in a varying degree with white; usually a whitish mark 
just above the eye; posterior portion of cervix and sides of 
neck, the scapulars, interscapulars, and upper tail-coverts mouse 
gray or deep mouse gray, more or less varied with darker sub- 
terminal borders and grayish white edgings; rump deep mouse 
gray, relieved in most instances with paler edgings; jugulum, 
breast and abdomen immaculate white; line of demarcation on 
sides of neck and breast nebulated gray and white; sides white, 
in two specimens with indications of gray; flanks mouse gray, 
the feathers narrowly tipped with grayish white; general as- 
pect of lower tail-coverts white, bordered and tipped with gray, 
the lateral feathers being varied with mouse gray, particularly 
on the outer web, and the partially concealed central ones being 
deep mouse gray, apically at least; primaries outwardly black, 
the shorter ones frosted with gray, and the inner webs of all 
extensively white; the secondaries, except innermost, mouse 
gray, margined with grayish white, and largely white on inner 
web; the innermost secondaries blackish brown, some of them 
tipped with grayish white; tertials blackish brown, more or less 
washed with gray and tipped with grayish white; lesser wing- 
coverts blackish brown; middle coverts blackish brown, the 
outermost sometimes mouse gray with paler edgings; greater 
coverts light mouse gray, margined with grayish white, the

lining of wings and axillaries white; inner edge of wing with 
a narrow broken border of mouse gray and blackish brown; 
two lateral rectrices mouse gray (or dark brown frosted with 
gray), tipped with grayish white; the other rectrices black. 
In the majority of specimens gray filoplumes occur on the 
head and cervix. Two of the University of California males 
exhibit abnormal tail development, No. 18682 having fourteen 
rectrices (seven of them still in the sheath) and No. 18685 
thirteen rectrices. 
The moult of Buller’s Shearwater does not appear to differ 
from that of other Southern Hemisphere shearwaters occur- 
ring off Point Pinos during the northern autumn.
