Vor. Ti Pra th) LOOMIS—A REVIEW OF THE TUBINARES 117 
With the exception of four July (1905) specimens from the 
ocean off Banda Point, Lower California, the Academy’s series 
was taken as follows in the vicinity of Point Pinos, California: 
August, 1907, four specimens; September, 1907, eighteen, 
1909, one; October, 1907, twenty-two; November, 1907, thir- 
teen; December, 1909, one, 1912, fifteen; January, 1908, 
eleven, 1910, two, 1913, one; February, 1907, twelve; March, 
1907, eighteen; April, 1907, seventeen. 
The four July birds are in faded brown dress. One of them, 
obtained on the 5th, is acquiring new feathers on the throat, 
jugulum, breast, abdomen, lower tail-coverts, crown, occiput, 
cervix, and dorsal region. Of the remaining three, all secured 
on the 7th, two are not quite so forward and one is further ad- 
vanced, its five inner primaries and greater and lesser coverts 
being in process of renewal along with feathers of the pileum, 
cervix, dorsal region, upper tail-coverts, and under surface, 
including lower tail-coverts. 
Much diversity exists in the moult of the four August speci- 
mens; none of which are hornotines. A specimen taken on 
the 7th has dropped all of the primaries except the distal one. 
Corresponding progress has been made in the wing-coverts, tail, 
and upper and lower parts. An example shot on the 10th has 
lagged behind. Seven worn outermost primaries and all of the 
old rectrices are in place, with feather growth active beneath 
the surface on the upper and lower tail-coverts, throat, jugu- 
lum, breast, abdomen, pileum, cervix, scapulars, interscapulars, 
and greater and lesser wing-coverts. A bird of the 30th has 
shed all the old primaries, while another of the same day has 
kept three of them on the right wing and two on the left. 
September specimens also show unequal advance in their 
feather renewal. Thirteen retain old primaries as follows: 
One of the 30th, the first primary; two of the 18th and one 
each of the 23rd, 25th, and 27th, the two outer primaries; two 
of the 4th and one each of the 18th, 23rd, 25th, and 27th, the 
three outer; one of the 2nd, the four outer. The worn condi- 
tion of the old primaries plainly indicates that these birds are 
not young-of-the-year. Of the remaining six examples, one 
of the 2nd, one each of the 4th and 25th, and three of the 27th 
have moulted all of the old primaries, prominent age-marks.
