Birds of Celebes: Caprimulgidae. 
Variation. The spots on the throat vary in size in both sexes and are sometimes almost 
confluent, often not pure white but buff, this latter colour being apparently a 
sign of immatmity, as also is the buff colour of the white patches on the primaries 
(Hartert 13).

Distribution. Sumatra (Raffles 13, Faber c f); Java (Horsf. 1, Vorderman d); Billiton 
(Vorderman 10, ii); Banjermasin, S. Borneo (Hombroii b2, Mottley 2, 4, 5); 
Celebes (Meyer 3, 13, Everett 16, Doherty 17)', Lombok (Wall. 3, 4, 13, 
Doherty 16)', Sumbawa (Guillem. 7, Doherty 16)-, Flores (Weber 14)', Timor 
(Wall. 13). 
A single specimen only of this species obtained by Meyer was the sole 
proof of its occurrence in Celebes till September, 1895, when a second was 
killed at Macassar by Everett and determined by Hartert (16) as a perfectly 
adult male. Later two further specimens were obtained by Doherty in West 
Celebes. Meyer’s examj^le is now in the British Museum and is marked by 
Hartert as immature. 
The nearest ally of C. affinis is C. griseatus (Wald.) of Luzon, a rare bird 
in collections, which will probably prove to be only subspecifically distinct from 
C. affinis when the intermediate localities have provided ornithologists with spe- 
cimens. Walden (Tr. Z. S. 1875, IX, 326) speaks of this form as intermediate 
in dimensions between C. affinis and C. monticola of India and South China to 
Tenasserim, but not yet known, apparently, from the intermediate Malay Penin- 
sula. C. monticola is, however so much bigger than the other two that it is 
hardly likely that it will be found to intergrade with them. 
GENUS LYNCORNIS J. Gd. 
Distinguishable from Caprimulgus by having no rictal bristles, no white on 
the tail-feathers ; the parietal plumage lengthened so as to form “ear-tufts”. 
Outer toe with four phalanges, claw of middle toe pectinated. Hartert (1897) 
recognises 6 species ranging from N. E. India to New Guinea.

') Dr. Kutter (J. f. 0. 1882, 175) says that the egg of C. griseatus of the Philippines is verj* similar to 
that of C. affinis said to be described by Baron Konig-Warthauspu under C. hisignatus (J. f. 0. 1808, 373).
