Chetura picina was described by Tweeddale from a female 
specimen collected by Everett near Zamboanga, Mindanao, in 
April, 1878. The next specimens known are two males and 
a female that were secured by Whitehead in Leyte in 1896. 
About 1904 Mearns collected one or more specimens of this 
species in Mindanao. Since then this swift has not been seen, 
so far as-known, until 1920. Mr. E. H. Taylor recently re- 
turned from Mindanao and brought a few birds that he collected 
in the vicinity of Zamboanga. Among these was one specimen 
of Chetura picina collected on September 25, 1920, which 
Mr. Taylor very generously presented to the Bureau of Science. 
Andres Celestino, who was collecting in Cebu during December, 
secured a female of this species at Toledo, Cebu, on December 
21, 1920. It is curious that this species had not been seen 
for years and that these two specimens were collected within 
three months of each other. :

Ridgway has erected the genus Mearnsia for the reception 
of this species. In the two specimens of Chetura picina at 
hand the first primary is decidedly shorter than the second and 
longer than the third. The tail is relatively shorter than in 
Chetura gigantea, and the spines of the rectrices are also com- 
paratively short. 
Tachornis pallidior McGregor. 
Mr. W. Parsons collected a pair of paler palm swifts at Pag- 
sanjan, Laguna Province, Luzon, on January 6, 1921. I have 
collected this species near Manila and in Tarlac Province, Luzon. 
Hirundo striolata (Boie). 
On June 18, 1921, Prof. §. F. Light and I noticed from ten to 
twenty pairs of mosque swallows flying about the quarantine 
dock at Mariveles, Bataan Province, Luzon. Some nests were
