of this petrel in the British Museum (Natural History) taken in 
Panamanian waters out from Balboa August 22, and 20 miles south 
of Panama, September 9, 1924, by Lt. Col. H. J. Kelsall in whose 
honor this race is named.

(Charleston Harbor, S. C.) 
Brown pelicans were to be found daily over Bahia Damas, shifting 
about to some degree, so that the number present varied. Those ob- 
served were mainly immature, or adults with the white necks that 
mark the postbreeding stage, though occasionally individuals in full 
breeding dress were seen. No nesting colonies were recorded, though 
undoubtedly their rookeries were not far distant. When the tide was 
high they cruised about as usual in line, diving whenever fish were 
sighted. At low water groups of the great birds rested in the man- 
groves and on rock exposures on the beach. I saw one fishing after 
dark on one occasion, sighting it as it passed the electric lights at 
the Colonia Central. 
Two adults were prepared for specimens, a male with white neck, 
and a breeding female with the larger ovaries developed to a diameter 
of half an inch. Measurements are as follows: Male, wing 518, tail 
136, culmen from base 327, tarsus 79.4 mm.; female, wing 507, tail 
131, culmen from base 290.0, tarsus 74.7 mm. In coloration these 
two agree with birds from Taboga Island in the northern sector of 
the Gulf of Panama. The brown of the hindneck in the female is 
very dark, like that of Taboga birds, being darker than the average 
in pelicans of the southeastern United States. The Coiba birds how- 
ever are within the limits of variation of the race carolinensis, and 
are identified as that subspecies. I watched particularly for indi- 
viduals with exceptionally long bills but saw none that could represent 
the large-billed subspecies californicus of the coasts of California and 
northwestern México. 
The usual name for the alcatraz in these waters is cuaco.
