on the muddy bed of a saline lagoon making rushes at pass- 
ing insects. 
Several times I have noted males flying high in the air in 
a wavy style, often dropping several feet and then going up 
again. This was noticed on southern Indefatigable in No- 
vember and in January, and on Abingdon in September. 
Whether these were mating antics, or whether the birds were 
hawking for insects, I do not know. At Black Beach Roads, 
Charles, in October, they were seen chasing each other 
through the woods. 
The condition of the reproductive organs was noted as 
follows : 
November 3; Villamil, Albemarle; one in intermediate plumage had large 
testes. 
December 5; Duncan; two with enlarged testes. 
December 11; Duncan; enlarged testes. 
May 14, 15; Charles; small reproductive organs. 
On February 28, in the interior of Charles, I took two nests 
each containing three unfeathered young, another containing 
two, and another containing one. On March 2, in the same 
locality, one nest was found containing three well-grown 
young and several containing two each. On the same day, 
Mr. Beck found a nest 12 feet above the ground in a bush of 
Zanthoxylum pterota. The nest was a small, neat, compact 
cup of moss placed at the forking of a limb, and contained one 
fresh egg. The nest of this species, to all appearances, is the 
same as that of the Pygmy Vermilion Flycatcher of Chatham.

Chatham Island. 
The habits of this species are like those of the Gould’s Ver- 
milion Flycatcher. It was not common near the beach at 
Wreck Bay, but about a mile up the road it became quite 
common, and was found in all of the wooded region below EI 
Progreso. On February 22, one or two individuals were seen 
in the lemon trees planted in the upper grassy pasture land 
above El Progreso. Mr. Beck took a number in the elevated 
moist region, high on the mountain above Basso Point, on
