1875.] THE PHILIPPINE AECHIPELAGO. 325 



]I(ib. Luzon, in January {Meyer). 



The male is distinguished from the female by having the region of the ears deep rufous ; 

 and all the other male members of the genus display more or less rufous on the ear-coverts. 



Luzon examples have the wings nearly half an inch longer than Sumatran and Malaccan 

 individuals in my collection. Otherwise no material difference is to be observed.

A species belonging to that section of the genus of which C. fmncica may be considered 



the type. It is the smallest of all the known species of that group, its dimensions not exceeding 



those of C. fucijiliaf/a (Thunb.) = C'. Hnchi (Horsf.). A narrow, well-defined, pure white band 



crosses the rump, and constitutes its chief differential character. ^ r, c .

British Museum, and bear on their labels Malacca as their halitat. They were obtained from 

 Cuming; and Mr. G. R. Gray (List of B. /. c.) gave Malacca as the origin of the species. 

 Mr. Wallace (/. c.), who was the first author who described the types, suggested the Philippines 

 (although with doubt) as a habitat of the species in addition to that of Malacca. Dr. v. 

 Martens {I. c.) without hesitation identified the Philippine form of Collocalia with C. troglodytes. 

 And, finally, Mr. G. R. Gray (Ann. N. H. I. c.) in 1866 abandoned Malacca as its halitat and 

 substituted the Philippines, to which archipelago he restricted it ; and so it stands in the Hand- 

 list {I. c). Mr. G. R. Gray has nowhere stated his reasons for this alteration of the habitat he 

 had originally assigned. But there seems to be little doubt that he arrived at a sound con- 

 clusion, and that C. troglodytes represents one of the Philippine edible-nest constructing Swifts. 

 The Malaccan Collocalia is identical with C. francicu. Whether a species belonging to the 

 C. fvciphaga group is likewise found in the Malay peninsula and adjacent islets is unknown, nor 

 has a species of that group been as yet discovered by any naturalist in the Philippines. 



The specimen contained in the Vienna Museum, and stated by Herr v. Pelzeln {I. c.) to have 

 been obtained at Manilla by Cuming, so far as description goes, agrees well with the British- 

 Museum types.
