small sexual organs. Specimens taken on Charles on May 14 
and 15, also had their reproductive organs much reduced 
in size. 
On August 10 and 11, high up on the east side of Cowley 
Mountain, Albemarle, the remains of cuckoos were found in 
two places. They had perhaps met violent deaths owing to 
the presence of cats. At Wreck Bay on July 7, I shot a 
cuckoo which did not have a vestige of a tail—perhaps also 
the work of a cat. 
The bill of the bird in life is black and the feet pale blue.

Wenman islands. 
The Gould’s Vermilion Flycatcher was found along the 
seashore, in the dry region, in the moist region, and in the 
grassy region of the higher mountains. Native and intro- 
duced vegetation was frequented alike. 
It was common on Albemarle, Charles, Indefatigable, and 
James. Mr. Hunter shot a lone individual on Wenman on 
September 24, demonstrating that this species also leaves its 
home island. None were seen on Barrington or Narborough, 
although reported by other expeditions. 
Their methods of hunting are like those of the Galapagos 
Flycatcher. They haunt the bushes and trees in search of 
insects. On Tagus Cove Mountain I saw a young one in 
striped plumage catch an insect on the wing. Another time 
I saw an immature male devouring a small butterfly while 
sitting on a branch. In one case one took insects from Mr. 
Williams’ hand, and as a rule they were very tame, approach- 
ing within a foot or two of one, and often being killed with 
a short stick. One was noted eating a small scorpion during 
our stay on Cowley Mountain. On southeast Albemarle 
they were common in a large slaughter field above Santo 
Tomas. There they were seen catching insects on the putrid 
remains of numerous cattle which had been slaughtered 
from time to time for their hides. At Academy Bay, Inde- 
fatigable, these flycatchers were seen at various times standing
