distinguishable. It comes very close to Caprimulgus macrurus 

 macrurus, with which it seems to be practically identical in size, 

 not smaller as Mr. Mathews says in the original description, 1 for he 

 compared it evidently with the large form here separated as Capri- 

 mulgus macrurus mesophanis, instead of with the typical small bird 

 from Java. I am here recognizing it largely on account of its 

 isolated range as compared with Caprimulgus macrurus macrurus, 

 and in the probability that careful comparison will reveal characters 

 to separate it from the latter race. 



CAPRIMULGUS MACRURUS KEATSI Mathews. 



[Caprimulgus] schlegelii Gray, Hand-List Gen. and Spec. Birds, vol. 1, 1869, 

 p. 57 (Am Islands; Dorey, New Guinea; Waigiou Island, Molucca Islands 

 [type locality, Dorey, New Guinea]) (nomen nudum). 



Caprimulgus macrurus Tceatsi Mathews, Novit. Zool., vol. 18, January 31, 1912, 

 p. 291 (Point Keats, Northern Territory, Australia). 



CJiars. subsp. — Similar to Caprimulgus macrurus mesophanis, but 

 smaller, and paler, both above and below. 



Measurements. — Male: 2 Wing, 183 mm.; tail, 139; exposed cul- 

 men, 10; tarsus, 15. 



Female: 3 Wing, 174-182 (average, 177) mm.; tail, 132-136 (134.7); 

 exposed culmen, 9.0; tarsus, 16.5. 



Type-locality. — Point Keats, Northern Territory, Australia. 



Geographical distribution. — Northern Territory of Australia; New 

 Guinea; New Britain Island; Aru Islands; and probably also the 

 Timorlaut Islands. 



The single Australian specimen examined indicates that this is a 

 recognizable race. Mr. Mathews in his original description 4 states 

 that it is smaller than Caprimulgus macrurus macrurus, but here 

 again he has doubtless made comparison with Caprimulgus macrurus 

 mesophanis, instead of the typical race from Java. This Australian 

 bird is apparently of the same size as* Caprimulgus macrurus macrurus, 

 but is distinguishable by its paler coloration, particularly on the 

 upper parts. 



So far as I am able to judge from the limited series at my com- 

 mand, birds from New Guinea, allowing for the usual range of indi- 

 vidual variation, do not differ in either size or color from typical 

 Caprimulgus macrurus Iceatsi of the Northern Territory in Australia. 



This subspecies was long ago given a tentative name by Mr. G. R. 

 Gray, 5 in the following fashion:
