VISCOUNT WALDEN ON THE BIEDS OF CELEBES. 115 



ventral region and the under tail-coverts are fulvous, without any markings. The major 

 wing-coverts are distinctly banded with alternate rufous and brown. A large white spot 

 on each of the first four primaries. The chin, throat, and upper breast are clothed with 

 feathers finely marked with fulvous-grey points on a brown ground. Many of the 

 upper breast-feathers with bold rufo-fulvous tips. The middle rectrices have the 

 general colouring and marking of the upper plumage, and are traversed by eight or 

 nine more or less distinct irregular black bands. The two outer pairs are pure white 

 throughout their entire length. The wing in six examples averages 6-25 inches, and 

 the tail 4-25. 



This species, as has been well observed by Mr. Blyth (Cat. Calc. Mus. p. 84, note), is 

 as diminutive as C. monticola, Frankl. 



2. Capeimulgus, sp. 1 



A large dark-coloured Caprimulgus is among the novelties obtained in Celebes by 

 Dr. Meyer. The example is unfortunately in such indifferent order that the inherent 

 difficulties which attend the discrimination of many species of the family are very much 

 increased. Above, this Celebean Goat-Sucker closely resembles Javan examples of C. 

 macrourus, Horsf. Underneath, it is darker in colour, and the transverse barring of the 

 abdominal plumage is less regular and well defined. The principal points in which it 

 differs from a considerable series of C. macrourus are : — the great length of the rictal 

 bristles, which measure a full inch ; the greater length of the bill ; the smallness of the 

 terminal white spots on the two outer pairs of rectrices ; and the peculiar markings on 

 the under surface of all the rectrices except the middle pair. In true C. macrourus 

 the white terminal spot on the outer pair of rectrices measures about two inches ; in 

 this individual it measures only seven eighths of an inch. In the Javan bird the under 

 surface of the rectrices is more or less uniform brown, without markings; this 

 Celebean bird has some eleven or twelve distinct narrow rufous bars crossing the 

 rectrices. Its first primary has no white spot, while on each of the three next it is 

 much smaller than in C. macrourus, which has a large white spot on all four primaries. 

 The length of wing is equal to the average length observable in the Javan bird, seven 

 and a quarter inches ; nor do the dimensions of the tail (six inches) differ. 



As there are two Bornean species, C. arundinaceus, Jacq. & Puch., and C. binotatus, 

 Bp., which have yet to be satisfactorily identified, I refrain from conferring a distinct 

 title on this Celebean Nightjar.

A single specimen obtained by Dr. Meyer in North Celebes is not to be distinguished 

 from a British-killed example of the adult Common Cuckoo. The wing alone is 

 shorter, 7*50 against 8-31 ; the tail is equal. Two other specimens, with the upper
