species of the Woodpecker Microstictus^ one occurring in North, the other in 
South Celebes, the two subspecies of Caprimulgus macrurus, which appear to be. 
of about equal value , are found one in India, the other in the East Indies 
and Australia.

Diagnosis. This species, with its Philippine ally C. manilensis, differs, according to Hartert, 
from C. macrurus chiefly in the smaller extent of the white spots on the primaries 
and of the white tips of the lateral rectrices, especially in the latter (white tips of 
two outer pairs about 25 mm broad, in macrurus about 50 mm). Abdomen brownish 
huff, barred with dark brown, but not so regularly as in C. macrurus, the broader 
buff tips of the feathers producing a more spotted appearance. 
Measurements. Total length 305 mm; wing 180; tail 147; tarsus 20; mid. toe with claw 
26.7; culmen 21.6; longest rictal bristle 35.6 (Glrant 1). 
Distribution. Celebes (Meyer a 1, b 1, 1)\ Lembeh Id. (Nat. Coll, in Hresd. Mus.). 
A single specimen of this species now in the British Museum was obtained 
by Meyer in Celebes — probably in the Minahassa — in 1870 — 1871. It 
was not immediately determined by Lord Walden, and Briiggemann having- 
received the foregoing C. macrurus from Gorontalo expressed the opinion that 
Meyer’s example would prove to be the same, but he apparently overlooked 
Walden’s determination of the specimen as manilensis in a subsequent work 
(a 1). Walden’s decision was confirmed by Mr. Hartert, but Mr. Ogilvie 
Grant who has recently had occasion to compare the Celebesian specimen with 
Philippine ones, remarks: “How the bird from Celebes came to be identified 
with C. manillensis^ G. B. Gray, by both Lord Tweeddale and Mr. Hartert 
I am at a loss to understand, for two more totally distinct species of Goatsucker 
can hardly be imagined. In the Celebes bird the rictal bristles are much longer 
and stouter than in any other species of Caprimulgus^ and extend far beyond 
the end of the culmen, the longest ones being about once and a half the length 
of the culmen from its base, and more than twice as long as the exposed part 
of the culmen. This character alone is sufficient to distinguish the Celebes 
bird at a glance, for in C. manillensis the bristles are very much finer and are 
very little longer than the culmen. The example from Celebes (apparently not 
quite adult, the primaries being tipped with buff) is most nearly allied to 
C. andamanicus Hume, the two outer tail-feathers being rather narrowly tipped 
on both webs with white, the white extremity being less than an inch in length ;
