 Mus. Comp. Zool. nos. 2712 ( c? ) and 2715 ( Q ), Bangs Coll. Collected 

 by Austin II. Clark July 14 ( <?) and July 7 ( $ ), I'.HU. 



Characters. Similar to T. doliatus fraterculus Berlepsch and Hartert 

 of Venezuela and Trinidad, but somewhat smaller with somewhat smaller 

 bill ; adult cT with the black bands below still narrower the under parts 

 being white very narrowly and rather irregularly barred with black; 

 white bands on tail as in T. doliatus dolialus (Linn.) of Surinam. Adult 

 $ exceedingly pale, the upper parts, except pilium, ochraceous, as pale 

 as in the Yucatan form T. doliatus yucatanensis Ridg., from which the 

 female of the new form differs little except in smaller size. 



Measurements. 



Remarks. As Thamnophilus doliatus has now, by general consent, been 

 divided into a number of subspecies, I feel little hesitation in adding an- 

 other quite as good, it seems to me, as those already recognized. Indi- 

 vidual variation in this species must, however, always be reckoned with, 

 and series, not individuals, compared. 



The pale colors of the female of the Margarita Island form have already 

 been mentioned by Cory in his list of Birds of the Leeward Islands, based 

 upon Ferry's series of fourteen skins, of which eight were females.

 well as relatively broader bill; adult male with red of under parts and 

 pileum more crimson, less orange about geranium red.
