and bill altogether larger and stouter. Adult 6 (tj-pe, Xo. 0784G, T. S.

 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

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

 white, bordered beneath by a loral and postocular streak of dusky gray 5 

 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, aud inner 

 edges of roctrices pale buify yellow; lining of wing white, tinged with 

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

 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,

3. Vireo approximans, sp. nov. 



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

 the yellow su[)raloral streak much less distinct; the yellowish iiostocular 

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

 {type, Xo. 97847, U. S. Nat. Mus.): Pileum and najie brownish gray, 

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

 .32; depth at base, .20; width, .23; tarsus. .90: middle toe, .45. 



It is not a little remarkable that this species, like the Certhioia from the 

 same locality, should have its nearest ally in a Bahaman species ( F. crassi- 

 ro.stri^^, Bryant). The resemblance to the latter is indeed so close that 

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

 tion of certain 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 butfy yellowish 

 beneath, with the supraloral l)ar intense sulphur- t)r lemon yellow, while 

 the other t\\o are dull bully Mhitish beneath, with the supndoral mark 

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