Mr. Havtert I am at a loss to understand, for two more 

 totally distinct species of Goatsucker can hardly be imagined. 

 In tlie 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 ex- 

 ample from Celebes (apparently not quite adult, the primaries 

 being tipped with buff) is most nearly allied to C. andanianicus, 

 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 ; the white spots on the inner webs of 

 the primaries are small, but clearly defined. 



I propose to name the Celebean bird Caprimidgus celebensis. — V-^ 

 Its measurements are as follows : — Total length 12 inches, 

 wing 7'1, tail 5"8_, tarsus 0*8, middle toe and claw 1*05, cul- 

 men 0*85, longest rictal bristle 1*4.

65. Lyncornis mindanensis, Tweeddale; Hartert, Cat. 

 B. Brit. Mus. xvi. p. 605 (1892). 



If these two forms, the types of which are before me, are 

 really distinct species, then both occur in North Luzon, for 

 out of four specimens of Lyncornis sent by Mr. Whitehead, 

 three are typical L. macrotis, perfectly similar to Vigors^s 

 bird, and the fourth agrees perfectly with Tweeddale's types 

 of L. mindanensis. Personally I am inclined to believe that 

 the latter are merely younger examples of the same species. 

 The darker head and shorter wing may be characteristic of 

 youth, as it seems unlikely two closely-allied forms should 

 occur in the same locality.
