188 THE AMERICAN NATURALIST. | (Vor. XXXIX. 
One female was taken in the Cienaga, May 23, 1904. 
14. Nyctanassa violacea (Linn.). *GuANABA."— Recorded 
from Isle of Pines by Poey, Cory, and Gundlach. None were 
seen by Zappey nor by Palmer and Riley. 
J I5. Nycticorax nycticorax naevius (Bodd.).— In March, 
1902, a flock of Black-crowned Night Herons was seen at a 
fresh-water lagoon in the northern part of the island and two 
others in a salt lagoon at Bibeyhagua. It is also recorded from 
the island by Poey. 
16. Butorides virescens maculata (Bodd.) “ AQUAITA." 
— The Green Heron occurs, in small numbers, wherever there 
is fresh water, and was also occasionally seen along the sea- 
coast. 
As has been pointed out by Riley, all West Indian Green 
Herons are much alike, and must be called by Boddzrt’s name. 
The form differs from true virescens of the mainland chiefly in 
being smaller. 
Two males were taken : one at Bibeyhagua, May 15, the other 
at Santa Fé, April 20. 
17. Butorides brunnescens (Lembeye).— Two specimens 
of this dark-colored bird were taken by Palmer and Riley near 
Nueva Gerona. 
We cannot avoid a strong impression, despite its peculiar 
coloration and the fact that young individuals are as different as 
adults from 2. virescens maculata, that this supposed species is 
a color phase of the ordinary bird. This, however, can be 
proved by careful observation only, by ascertaining whether the 
two breed together or mate each with its own kind only. 
18. Ardetta exilis (Gmel.). — The Least Bittern was abun- 
dant in the Cienaga in March, 1902. On the 1904 trip, made 
later in the spring, none were found anywhere, leading to the 
conclusion that those seen in March were winter residents and 
that the bird does not breed in the Isle of Pines. 
19. Botaurus lentiginosus (Montag.). — Recorded by Cory 
and Gundlach from the Isle of Pines, but not observed by Zap- 
pey nor by Palmer and Riley. 
20. Eudocimus albus (Linn). “Coco.” — One of the 
commonest and most characteristic birds of the Cienaga, flocks
