 half of ear coverts, malar region, chin, throat, and -foreneck uniform 

 black; the first with a distinct central spot of white. Sides of occiput 

 and neck and terminal half of ear coverts, burnt umber or brownish 

 chestnut; under surface of body, deep brownish slate, darker and clearer 

 on chest; under tail coverts, rich chestnut; Bill wholly deep black; 

 legs and feet dusky horn color. Length (skin), 0.00; wing, 3.50; tail,

One of the alleged types of F. analis (Lafr.) in the collection of the 

 Boston Society of N^atural History (Lafresiiaye collection, No. 5053) 

 appears, from the memoranda wliich I made during its inspection a year 

 or more ago, to be referable to this form. Its measurements are as 

 follows: Total length (mounted specimen), 0.70; wing, 3.70; tail, 2.20; 

 exposed cnlmen, 0.80; tarsus, 1.22, 



The other alleged type of F. analis (Lafresnaye collection ISo. 5052), 

 on the same evidence, is F. crissalis (Cab.) (See p. 071.) 



Comijared with F. hoffmanni (Cab.), F. saturatus differs as follows: 

 The pileum is darker and decidedly less reddish brown, without any 

 cinnamomeous tinge on the foreliead. The sides of the occiput and 

 neck are far less distinctly cinnamomeous, being merely tinged with 

 this color. The general color of the ujiper parts is very decidedly less 

 russet, being of a nearly pure olive-brown with the rump less tinged 

 witli rusty brown, and the upper tail coverts duller rusty brown. The 

 under parts are decidedly darker and more uniform; the whole chest 

 and breast nearly clear slate color; the belly lighter but not approach- 

 ing white; and there is much, less of an olive tinge on sides and flanks; 

 the under tail coverts are of a deeper or brighter tawny cinnamon- 

 rufous.
