When I described this form I had only one badl^v-shot, half-destroj'ed specimen. 

 Both I and Salvador! omitted to com[)are the West Ecuadorian birds with the most 

 closely allied /•'. niqricnpillus Ridgw. (ex. Cherrio MS.*) from Central America. 

 When the author described F. iii^/ricapilliis he made the type a Costa Rica specimen, 

 but said that this species extended from Costa Rica to Western Ecuador, at the 

 same time describing a specimen from Sta. Rita, W. Ecuador, as differing from 

 Costa Rica birds in being " less castaneous or rufescent above (nearly jiure 'bistre' 

 on the back) and more extensively slaty beneath, while thr hindneck, instead of 

 being similar in colonr to the back (as in both Costa Rica specimens), is dark 

 slate-colour, like the chest, and the under tail-coverts bright rufous tawny. It very 

 likely represents a local race." 



Having now before me a series of the W. Ecuadorian form from Faramba, 

 Cachyjacu, S. Javier, Carondelet, and Lita, and several Costa Rica specimens (Care- 

 bianco de Sarapiqni, collected by C. F. Underwood), I find that, indeed, the 

 former (while very closely allied to niyricapillus) can be separated. We have tlins, 

 according to ray views, three distinct subspecies : 



1. Forinicarius analis analis (I/afr.), original locality Bolivia, extending to 

 eastern Pern : top of head olivaceous-brown, like the back, with centres of feathers 

 only blackish, sides of neck like crown, but somewhat lighter, back clear olive-sepia 

 or bistre-brown. 



•Z. Formicarius analis ili'stnictiis Hart., original locality Paramba, extcmlingall 

 over N.W. Ecuador : top of head brownish black, in contrast to the back, which is 

 rufous-olive (almost bistre in the middle of the back in some specimens), brighter 

 rufons, almost chestnnt-brown on the rump and njiper tail-coverts, sides of neck like 

 crown, only more slaty, hindneck blackish, or more or less distinctly slate-colonr, 

 like the crown, or (generally) lighter, more slaty. Bill from nostril to tip 

 13i-14i mm. 



3. Formicarius analis niyricapillus Ridgw., original locality Costa Rica, extend- 

 ing to Panama : exactly like F. a. i/cstnicti/s, hat above darker, richer rnfous-brown, 

 gradually merging into deep chestnut-brown on rump and tail-coverts, less tinged 

 with olive on the back, hindneck like back, not slaty. Bill from nostril to lip 

 15i-10 mm. Bill therefore longer ! 



Two eggs, said to belong to F. a. destructus, are white without gloss, more 

 pointed on one end, and measure 2',)^ x '.i^^ and 30^ x 22i mm.
