Anioiiy; the eleven dS iid. ol' S. s. IciKO/stifima coiii]i:irecl by lue, there is not 

 a single specimen thut luis snch small, dot-like markings on the wing-cuverts as 

 S. s. schistacea. 



? ad. Top of the head dnsky slate-colour or dark slate-grey, in strong contrast 

 to the dark rnfescent brown back. Upper wing-coverts a little darker brown than 

 the latter, terminated by large, ronnded f'nlvous spots ; (|uills dusky, dull rufescent 

 brown on the outer webs : tail dull blackish. Lores greyish ; cheeks, malar region 

 and oar-coverts slate-grey, rather lighter than the pileum. Whole lower snri'ace 

 deep ferruginous, nearly whitish on the chin ; flauks washed with rufescent brown. 

 U]iper mandible blackish, lower one whitish. 



The specimens from British Guiana, Cayenne and iSurinam are practically 

 identical with Pelzeln's types from Barra do Rio Negro. Hence, //. simjjlex 

 becomes a synonym of P. Icucodiyma.

S ad. Agrees with S. s. schistacea in the dark schistaceous colour above and 

 below, and in having the bill entirely black, but dilfers in its rather deeper black 

 wing-coverts with much larger white apical sjwts, which are quite as large as in 

 & 5. Icucostigma. 



? ad. Not distingui.-shable i'rom that of S. s. Ici/costit/i/ta ; bill perhaps a little 

 shorter. 



Tlie distribution of the four subsjjccies is as follows : 



1. ''Sclatcria schistacea schistacea (Scl.). 



Central Peru: La Merced (2000 ft.), La Gloria (3200 ft.), Borgoiia (2(iOi) ft.) 

 [Kalinowskl coll.] ; Pozuzo, prov. Huanuco (2400 ft.) [\V. Hoffmanns coll.]. — 

 S.E. Peru: Cuzeo, Marcapata (30011 ft.) [0. Garlc]ip coll.]. 



Thus, this bird is an inhabitant of high elevations, and 1 doubt the correctness 

 of the original locality : " Rio Jacarri." 



2. S. schistacea sttbplumhca (Scl. & Salv.). 



East Ecuador: Sarayai;u (Buckley coll.); Zamora (Fraser coll.). — y.E. Peru: 

 Iquitos, on the Amazons (11. Whitely eoll.j. — Colombia: Llanos of the Rio Bleta, 

 between ,S0() and 1500 ft. {\\ . T. Wheeler coll.) ; Bo<iotd coll. (Mus. Berlepsch, 

 Brit). 



3. S. schistacea leucostignm (Pelz.). 



Xorth Brazil: Barra do Rio Negro, Marabitanas, Rio Vanpe (Natterer coll.), 

 — Caijemie : Ipousin (Cherrie coll.), St. George d'Oyajioc (Jelski coll.). — Surinam : 

 Maroui River (Bartlett coll.). — British Guiana : Bartica Grove, Camacusa, Takutu 

 River, Merume Mountains (H. Whitely coll.).
