82 PROCEEDINGS OF THE NATIONAL, MUSEUM, vol. 64. 



whitish and spotted on the chest with obscure spots of huffy citrine; under 

 tail coverts citron yellow ; flanks yellowish citrine ; wings chaetura drab, the 

 feathers edged externally with the color of the back, the tips of the greater 

 coverts a little paler, but not forming a bar ; bend of wing edged with citron 

 yellow ; under wing coverts whitish ; remiges below hair brown, the feathers 

 where they rest against the body bordered with whitish or internally pale 

 buff; tail above olive with a citrine wash, the outQr edges of the feathers 

 brighter basally. Wing, 58; tail, 40; culmen, 11; tarsus, 20.5; middle toe, 

 9.5 mm. 



The nearest ally of this species is evidently Cryptolopha sarasinorum Meyer 

 and Wiglesworth, from which it differs in lacking the crown stripe and the 

 white on the two outer rectrices. 



To the above original account I would like to make one correction : 

 The two outer rectrices on each side are very narrowly edged on 

 the inner margin with yellowish white, almost obsolete and some- 

 times absent, being easily overlooked. This is nothing like the con- 

 dition in Cryptolopha sarasinorum, but is an approach and shows 

 their relationship. 



The above series is fairly uniform. Some specimens are more 

 whitish below; in fact, the whitish predominates over the yellow 

 streaks, while in others the reverse is the case. Tlie whitish is more 

 pronounced on the abdomen and throat as a rule. The buffy citrine 

 spots on the chest form a bar in one specimen (No. 252075), while in 

 others they are almost absent. Above there is not much variation; 

 some specimens have the top of the head hardly different in color 

 from the back, but as a rule it is deeper and darker. The sexes are 

 alike. 



In the original description only the measurement of the type was 

 given. The series measures as follows : 



Fifteen males measure: Wing, 55-62 (58.7) ; tail, 40-44.5 (42.2) ; 

 cuhnen, 10-11 (10.3) ; and 12 females: Wing, 52.5-59.5 (55.8) ; tail, 

 36-44.5 (40) ; culmen, 9.5-10.5 (10.1). 



Since writing the above, Mr. J. H. Fleming has kindly loaned the 

 National Museum two topotypes of CTyptolopha sa7'asinorum. 

 They only emphasize the differences pointed out above, the lack of 

 a central crown-stripe and restriction or absence of white on the 

 outer rectrix in Cryptolopha nesophila. 



In the absence of the crown-stripe and the very narrow whitish 

 edging on the inner web of the outer rectrices, C. nesophila ap- 

 proaches C. nigromm of the Philippines, but is darker above, with 

 only streaks of yellow below, and there are other minor differences, 

 C. nesophila probably had a Philippine origin, while C. sarasinorwm 

 was derived from the islands farther south. 



Cryptolopha as at present constituted is not a homogeneous group 

 and needs revision. Indeed, Stresemann *■' has removed Cryptolopha
