allows it to e( flop about ” in an apparently purposeless 
manner. 
The colours of the soft parts in young males and young 
females are as follows :— 
Bill pale bluish grey, light lavender-blue at base. 
Interramal bare space pale lavender-blue, darker here and 
there. 
Iris sepia-brown; circumorbital bare space dark cobalt-blue. 
Webs and feet pale flesh-coloured. 
The two birds from which the notes of these colours were 
taken were a male and female respectively, with the entirely 
black head and nape. I took them home in a frozen state 
to Mr. Pycraft, and together we tried to distend the gular 
sac by artificial means, but after repeated efforts failed to 
do so.

We found numbers of these beautiful birds breeding in 
holes among the broken masses of rocks which were strewn 
everywhere on the steep slopes of the island, but not 
until we had reached an altitude of about 300 feet. No 
attempt at making any sort of nest is made. At the 
time of our visit the nesting-places contained both eggs and 
downy young. The breeding-habits do not appear to differ 
in any particular from those of P. americanus , except in 
regard to the time of year at which the birds commence. I 
have found the latter species breeding in the Bermudas in 
the middle of May.

I noticed a fair number of these Ground-Doves. They 
were exceedingly tame and allowed us to approach within 
three or four yards of them. The specimens I secured are 
the palest I have seen.
