Herr E. Hartert on the Caprimulgidse. 281 



Lave not been able to examine the type in the Paris Mnseum, 

 but the figure splendidly represents a female of C. affims. 

 It is true that the white patch on the throat seems to be 

 extended too far in the middle, but this often occurs in 

 skins if the feathers are a little displaced. It is also to be 

 noted that Motley procured C ajfinis at Banjermassing, the 

 locality whence the type of C arundinaceus came. Two very 

 closely allied forms are seldom found in the same district. 



Recently Dr. A. B. Meyer (Sitzungsber. u. Abhandl. Ges. 

 Isis, 1884) has described as a new species C. faben from 

 West Sumatra. The author admits that his C.faberi closely 

 resembles the figure of C. arundinaceus, but proceeds to point 

 out some difterences. These difi'erences, however, cannot 

 serve to distinguish the Sumatran form specifically. First, 

 regarding the habitat : this has little value, since I find 

 that a specimen from Sumatra is nndistiuguishable from 

 C. affinis from other localities. The darker coloration of the 

 upper surface in the supposed new species {C.faberi) is of 

 no consequence, since rather dark and rather pale specimens 

 occur in the same localities, as the series in the British 

 ]\Iuseum and several other specimens which I have seen 

 clearly show. The lower abdomen and under tail-coverts in 

 C. affinis are always uniform, the bands on the inner w ebs of 

 the outer tail-feathers being occasionally absent on the inner 

 margin in females from several localities (Lombock, Celebes). 

 The minute and careful description of C.faberi clearly indi- 

 cates that it is a female. The greatest value seems to be 

 attached to the presence of wing-[)atches. I must, however, 

 remark that several females before me have no spot on the 

 outer web of the second primary, while others from the same 

 locality have it well developed. Therefore there is no doubt 

 in my mind that C. arundinaceus and C. faberi both belong 

 to C. affinis. 



(6) Caprimulgus alboxotatus and C. macrukus. 



The close resemblance of C. macrurus to C.albonotatus has 

 already been mentioned by A. O. Hume and E. W, Gates 

 (B. Burmah, ii. p. 20). The latter has made the following
