160 VISCOUNT WALDEN ON THE BIRDS 
Belongs to the same section as C. albonotatus, C. nigripennis, C. macrurus, and C. 
schlegelii. It agrees well with the single Celebean example above referred to. The 
two type specimens in the British Museum are not fully adult. Outer pair of rectrices 
with only the terminal portion of the inner web white. Both webs white in the second 
outer pair. This is probably the species observed by Dr. v. Martens in the collection of 
the Manilla Military Library and identified by him with C. macrurus, Horsf.

56. * CAPRIMULGUS GRISEATUS. 
Caprimulgus griseatus, G. R. Gray, Hand-list, no. 629, “ Philippines” (1869), descr. nulla. 
Founded on a single example, in the British Museum, obtained from the Philippines 
through the Brothers Verreaux. It belongs to the same group as C. monticola and 
C. affinis, being intermediate in dimensions. Wing 6:25, tail 4 inches. The type is in 
very grey plumage. More examples must be compared before its specific distinctness - 
can be established.

Mr. Blyth in 1842 (J. A. S. B. xii, 1, p. 245) expressed himself unable to see in what 
the Philippine Amethystine Cuckoo, as described by Vigors (J. c.), differed from the Javan 
and Malayan species, and in his catalogue of the Calcutta Museum, no. 354, identified 
the two forms under Horsfield’s title. But there is no evidence that examples had 
been compared; and no Philippine example was contained in the Caleutta Museum. 
* There can be little doubt that D’Aubenton figured Sonnerat’s type.
