Fifteen specimens were shot by Mr. R. H. Beck; a male on 
August 8, 1905, twenty miles northwest of Clipperton Island, 
and nine males and five females on the 4th and 5th of October, 
1906, in latitude 14° 24’ to 14° 28’ N. and longitude 107° to

Like numerous other petrels breeding in the South Temper- 
ate Zone, this species apparently extends its exodus-migration 
beyond the limits of the Southern Hemisphere. 
In unworn plumage, the feathers of the upper parts are 
washed as well as edged with gray; the wings, too, are more or 
less washed with gray, and extensively edged with grayish 
white. In one of the males the top of the head is ornamented 
with numerous silvery white filoplumes: 
In the August specimen a complete moult is well under way 
and in twelve of the October specimens it has reached the final 
stages. The two remaining October specimens (perhaps birds- 
of-the-year) are in somewhat worn plumage and show but 
little active feather growth. In several specimens a temporary 
white collar has been developed where loose feathers have 
fallen out exposing the basal white of the cervix. |
