for a youDger bird. This (received from Yerreaux, in the year 1815, 

 without a near statement of the locality) is quite like the old one de- 

 scribed above, only that the mantle is somewhat duller, the superciliary 

 stripe is not white, but yellow, the individual feathers bordering the 

 white throat-stripe and the coverts of the secondaries, nearly all show 

 a pale, bufi'y, whitish margin, which gives rise to a somewhat more dis- 

 tinct light cross-band on the wing; a second band, but by far less dis- 

 tinct, is indicated by the pale margins of the greater upper wing-cov- 

 erts." (Translation.) 



The measurements unfortunately are not given ; but the plumage as 

 described agrees very closely with that of the type of our G. finscM. 



While it is possible that the yellow superciliary stripe and pale wing- 

 covert tips indicate immaturity, the real young plumage, or first plum- 

 age, of the Certhiolse is very different from that of the adult, the boldly- 

 marked "pattern" of the latter being wholly wanting. At the same 

 time, in the case of the type of C. Jinschi the very different proportions 

 iiud dissimilar color of the back could hardly thus be accounted for. 



In the collection of the United States National Museum are five certhi- 

 olse, resembling C. dominicana, but differing in having the middle por- 

 tion of the superciliary stripe yellow, and the upper parts more slaty. 

 One of these is from Guadeloupe, and one from Dominica. The remain- 

 ing three are stated on the label to have been obtained in Dominica, 

 but the authority cannot, in this case at least, be depended on. These 

 are certainly not young birds of C. dominicana, although they may rep- 

 resent some special phase of plumage in that species. For the present, 

 however, I propose to consider them representing a distinct form, which 

 it is proposed to name 



CertMola sundevalli, sp. nov. (?) 



Sp. char. — Similar to C. domitncana, but superciliary stripe yellow 

 for at least the anterior half, and the upper parts more slaty. 



Adult (type No. 79953, U. S. Nat. Mus., Guadeloupe, W. I.; L. Guesde) : 

 Above blackish slate, darker on the head, the lower part of the rump 

 crossed by a narrow band of yellowish olive-green. Forehead pale 

 gray, darker anteriorly ; a superciliary stripe confluent anteriorly with 

 the gray of the forehead, extending back to the end of the auric- 

 ulars, and yellow for the anterior two-thirds, the posterior extremity 

 white; chin, throat, and cheeks, deep plumbeous; jugulum, breast, sides, 

 and abdomen yellow, paler and more grayish on the flanks ; anal region 

 and crissum dull white, the longer feathers of the latter grayish basally. 

 Lining of wing including axillars and inner margins of remiges pure 

 white. Inner webs of rectrices tipped with grayish white, that on lateral 

 feather extended nearly .40 of an inch from the tip. Wing, 2.40 ; tail, 

 1.65 ; culmen, .60, bill from nostril, .40 ; tarsus, .70 ; middle toe, .49. 



Three specimens, stated on the labels to be from Dominica, but per-
