Vow. Il, Pt. If] GIFFORD—BIRDS OF THE GALAPAGOS ISLANDS 241 
factorily identified. The breeding season on Charles seemed 
to be in March, birds being noticeably scarcer then. 
The condition of the reproductive organs was noted as 
follows: . 
November 6; south Indefatigable; not much enlargement. 
November 21; South Seymour; showed some enlargement. 
December 19; south James; the few taken showed no enlargement of the 
organs of reproduction, while two males taken on Jervis the day 
before had very large testes. 
May 14, 15; Charles; organs reduced in size. 
On January 12 two young, about a week from the nest, 
were taken near Academy Bay, Indefatigable. The following 
day two more of about the same age were taken. On January 
18 I obtained two in the same locality; they were but shortly 
from the nest. One of the young-of-the-year was taken on 
March 12 in the brush near the coast about 10 miles west of 
Villamil, Albemarle. Three days later, in the vicinity of Cape 
Rose, on the same island, several were seen close to the sea. 
In latter May, at Black Beach Roads, Charles, considerable 
numbers of this species were seen, but few were adult. 
That individuals of this species also leave the land at times 
is testified by the fact that on the morning of May 18, when 
about 20 miles south of Indefatigable, an immature one came 
aboard. A Dendreca petechia also visited us. 
This species was never noted bathing. It seems to have lit- 
tle or no competition as regards food. It is about as tame as 
the other finches. None was noted with diseased feet. Mr. 
Beck took a partial albino at Black Beach Roads, Charles, on 
June 4. It had several white primaries and rectrices and a 
number of white patches on its body. During our sojourn on 
Jervis on December 18 most of the birds seen were black 
males. 
26. Geospiza septentrionalis: NORTHERN Cactus FINCH 
Culpepper and Wenman islands. 
These birds were abundant and very bold on both islands. 
On the former they were taken on the landslide on the north 
side, this being the only accessible portion of the island, which 
is practically an elevated table land with precipices on all sides.
