Dendrocolaptes certhia Scl., Cat. Bds. B. M., XV, 1S90, p. 173. 



A male and female taken July i, iS87.'in the lowlands. 



[Mr. Sclater, who has examined the type of D. ol>solct/is Ridgw., con- 

 siders it inseparable from D. certhia Bodd. Of the last-named species I 

 have no examples for comparison, and as in any case the name obsolettis 

 is preoccupied, I follow Mr. Sclater in referring these specimens, for the 

 present at least, to D. certhia. — F. M. C] 



loS. Nasica longirostris {Vieill.). — Seen only about the river, where 

 it was common. 



109. Dendrornis susurrans {yard.). 



Dendroriiis fraterc/iliis Ridgw. , Proc U. S. Nat. Mus., X, 1887, p. 526, 



Dendrornis susurrans Elliot, Auk, 1S90, p. 171. 



A male taken June 10, 18S7, in a semi-palm forest twenty miles from 

 the river. 



[Mr. Elliot's examination of the type and single known specimen of D. 

 fraterculus, resulted in his referring it to D. susurrans (Jard.,) and with 

 this decision it may be well to agree until further material shall more 

 strongly urge the claims o( fraferculus to recognition. — F. M. C] 



[no. Dendrornis multiguttata {Lafr-') — Three apparently adult females 

 taken by Williams in June and July, 1883. Mr. Elliot in his recent review 

 of the genus Dendrornis (Auk, 1890, p. 175) mentions these specimens 

 one of which, taken July 30, he considers typical of D. multiguttata, 

 while the remaining two are said to "probably merely represent a reddish 

 phase of plumage, which I have noticed occurs sometimes with other 

 species of the genus." This view may account for the marked differences 

 in coloration which exist between the single July and the two June speci- 

 mens, but it does not so well explain the differences shown by the follow- 

 ing measurements (in inches) : 



It is not improbable that the largest specimen may have been incorrect 

 ly sexed, when these differences of size and coloration might be consid- 

 ered sexual. At any rate the present material is not conclusive, and fur- 

 ther specimens alone will decide whether these two small, reddish birds 

 are specifically identical with D. multiguttata. — F. M. C]
