15 
to fifty nests in the colony, although many were unoccupied. The 
nests are composed of a blackish brown hair-like moss? cemented 
with the characteristic glutinous saliva. The saliva serves also 
to hold the nests to the rock. The nests of Salangana whiteheadi 
examined by us were supported by little ledges, not fastened to the 
rock nor to each other. Plate II shows how closely associated were 
the nests of S. marginata, one wall serving for two adjoining nests, 
so that in most cases it would be impossible to separate two nests 
without destroying one of them. The eggs resemble those of other 
species of the genus. Those figured on Plate III measure, respec- 
tively, 0.72 by 0.43 and 0.67 by 0.46 inch. Three odd eggs, too 
far advanced in incubation to be blown, had the following dimen- 
sions: 0.67 by 0.43, 0.70 by 0.45, 0.69 by 0.44 inch. Many of the 
nests held young of various sizes. 
SALANGANA TROGLODYTES (Gray). 
A few observed and one taken in Romblon. Another specimen 
was taken in Sibuyan, where the species is not common. 
SALANGANA WHITEHEAD! (Grant). 
Very abundant in Sibuyan, where several specimens were taken. 
EUDYNAMIS MINDANENSIS (Linn.). 
Romblon and Sibuyan. 
CENTROPUS VIRIDIS (Ncop.). 
An egg of this species was taken from the oviduct of a female 
killed in Sibuyan, June 10, 1904. It measures 1.20 by 0.86 inches, 
and has a smooth, dull white surface which may be easily scraped 
off. This chalky outer layer is not so thick, however, as it is on 
eggs of the American Crotophage. Centropus viridis was seen in 
Romblon. also. 
PRIONITURUS DISCURUS (Vieill.). 
A few specimens of this racket-tailed parrot taken in Sibuyan 
had the tail broken or but incompletely grown. 
TANYGNATHUS LUZONENSIS (Linn.). 
Specimens of the Luzon parrot from Romblon and Sibuyan are 
in worn plumage. 
*Mr. Elmer D. Merrill tells me this is a scale moss of the family 
Jungermanniacee. In two nests only was any other material used, where 
leaves of Casuarina were mixed with the scale moss.
