and bill altogether larger and stouter. Adult 6 (type, No. 97846, V. S. 

 Nat. Mas.) : Pileum and nape brownish gray, the first darker laterally, 

 but the dusky hardly forming a distinct .streak: the gray of the nape 

 gradually assuming a more olive tinge on the back, this increasing in 

 intensity posteriorly, the rump and tail being decidedly olive-greenish. 

 A distinct superciliary stripe of pale brownish gray, or dull grayish 

 white, bordered beneath by a loral and postocular streak of dusky gray ; 

 auriculars and sides of neck pale olive-grayish, fading gradually into 

 dull white on malar region, chin, and throat; the latter bordered on each 

 side by a narrow line of dusky gray. Remaining lower parts dull white 

 medially, light greenish olive laterally, the anal region, crissum, and inner 

 edges of rectrices pale buffy yellow; lining of wing white, tinged with 

 sulphur-yellow; a very faint brownish gray shade across the jugulum. 

 Maxilla brownish black, paler along tomium; mandible pale browish 

 yellow (plumbeous in life ?) ; feet horn-color (plumbeous in life ?). Wing, 

 3.35; tail, 2.90; culmen, .85; bill from nostril, .50 ; depth of bill at base, 

 .28 ; width, .30 ; tarsus, .85 ; middle toe, .50. 



3. Vireo approximans, sp. nov. 



Sp. char. — Similar to V. crassirostris, Bryant, but rather paler above, 

 the yellow supraloral streak much less distinct; the yellowish postocular 

 spot obsolete, and tail more decidedly rounded or graduated. Adult $ 

 (type, No. 97847, U. S. Nat. Mus.): Pileum and nape brownish gray, 

 changing to grayish olive on the back, the rump, upper tail-coverts, and 

 outer web of rectrices more decidedly olive greenish ; wings dusky, 

 the middle and greater coverts broadly tipped with yellowish white, and 

 edged with olive; tertials broadly edged with dull whitish, the remain- 

 ing remiges more narrowly edged with light olive-green, changing to 

 pale grayish toward ends of the feathers. A broad and rather distinct 

 supraloral stripe or bar of pale buffy yellow; upper eyelid with a bar of 

 dusky grayish; a very indistinct brownish gray loral or anteorbital 

 spot. Lower parts pale buffy yellow, paler on anal region and crissum, 

 the sides grayish olive. Maxilla dark brown, mandible pale brownish 

 (in dried skin) ; legs and feet dusky (plumbeous in life ?) : Wing, 2.45 ; 

 tail, 2.20; graduated for .20 of an inch; culmen, .00; bill from nostril, 

 ,32 1 depth at base, .20; width, .23; tarsus, .90: middle toe, .4."). 



it is not a little remarkable that this species, like the GerthioJa from the 

 same locality, should have its nearest ally in a Bahaman species ( V.erassi- 

 rostris, Bryant). The resemblance to the latter is indeed so close that 

 I hesitated to separate it, but finally concluded to do so upon the detec- 

 tion of ceitain characters which, though slight, do not occur in either 

 of the four examples of V. crassirostris now before me. The Latter pre- 

 sent great variations in color, two of them being bright bully yellowish 

 beneath, with the supraloral bar intense sulphur- or lemon yellow, while 

 the other two are dull buffy whitish beneath, with the supraloral mark 

 pale dingy yellow. With these latter the pieseiit bird agrees most
