1. Certhiola tricolor, sp. nov. 



Sp. char. — Similar to C. hahamensiSj but larger, the upper parts 

 darker, yellow on rump more extended, and posterior lower parts pale 

 yellowish. Adult $ (type, No. 07844, U. S. Xac. Mus.): Above dull 

 black, iijcluding the whole of the exposed portion of the tertials and 

 secondaries. A broad and very distinct superciliary stripe of pure 

 -white, extending from the nostrils to the occiput; i)rimaries with a 

 large basal speculum of white, extending for about .40 of an inch 

 beyond the ends of the coverts; basal half of inner web of all the sec- 

 ondaries pure white; tbree outer tail-feathers broadly tipped with white. 

 Lower half c^f runjp lemon-yellow. Broad band on side of head, involv- 

 ing lores and auriculars, and passing beneath but not above the eye, 

 black; this band much narrower anteriorly, and gradually widening 

 posteriorly, where contiuent with the black of the nai)e. A small black 

 line along the lower edge of the rictus. Chin, throat, jugulum, and 

 ■cheeks uniform grayish white; whole breast and up[)er part of abdo- 

 men lemon-yellow, changing to oli^■e-gray on the Hanks and dull yel- 

 lowish white on anal region and crissum. Lining of wing i)ure white, 

 the bend bright yellow. Bill, deep black; feet, dusky. Wing, 2.00; 

 tail, 1.00; culmen, .55; de[>th of bill at base, .20; tarsus, .80; middle 

 toe, .50. 



Young, firat j)lumage (type, No. 97845, U. S. Nat. ^lus.): Above dull 

 grayish brown, the back indistinctly clouded with dusky, the forehead 

 mostly dull bhick (new feathers); rump dingy olive-yellow. An indis- 

 tinct superciliary strijie of ])ale dingy yellow, becoming nearly white 

 anteriorly. A narrow loral stripe of dusky passing beneath the eye, 

 but changing to dull grayish brown, and continuing, broadly, over the 

 auriculars to the na[)e. Lower parts dingy olive-yellow, brighter on 

 the l^reast and upper part of abdomen; anal region and crissum pale 

 buffy yellowish. Lining of wing pure white, changing to yellow along 

 the edge of the wing. Wing-speculum smaller than in the adult, but 

 «till very consi>icuous. 



It is somewhat remarkable, that the nearest ally of this species should 

 be the Bahaman C. hahameiisiH. It requires comparison with no other, 

 excei)t, perhai)s, (J. cahoti, Baiid, of Cozumel Island, Yucatan, which I 

 have not been able to examine in this connection. 



2. Vireosylvia grandior, sp. nov. 



Sp. guar. — Largest known species of the genus, somewhat resembling 

 F. barbademe, but much j-'rayer, the submalar streak niuch narrower.
