 22". Sclateria schistacea humaythae Hellm. 



Sclateria schhtacea humaythae Hellmayr, BuU. B. 0. C. xix. p. 51 (1907. — Humiytlia) ; Helltuiyr, 

 Nov. Zool. x\y. 1907. p. 37.5 (Humaytha. Paraiao). 



No. 1020. <S ad., Maruias, Rio Maehados, 15. vii. 1908.— Wing 08; tail 54; 

 bill 19 mm. 



No. 745. (J ad., Allianca, 5. xi. 1907.— Wing 70 ; tail 57; bill 19 mm. 



No. 791. ¥ ad., Allianca, 17. xi. 1907.— Wing 68; tail 53; bill 20 mm. 



Perfectly identical with the Hnmaytha series. The male from Allianca, in the 

 length of tail, approaches S. s. leucostigma. 



S. s. humaythae inhabits both banks of the river. On his first journey in 1906 

 Mr. Hoffmanns obtained a large snite at Humaytha, and a single female on the 

 opposite side, near Paraiso. 



228. Myrmelastes luctuosus luctuosus (Licht). 



Lan'im lucluosiis Lichtenstein, Ver:. Dubl. Berliner Jfus. p. 47 (182.3.--" Pari "). 



Thiiiiiiiophilus hictuosiiis Pelzeln, I.e. p. 7G (Borba). 



Myrmelasles luctuosus Hellmayr, Noo. Znol. xiv. p. 372 (Humaytha). 



Nos. 387, 523. ? ? ad., Calama, 12. viii., 7. ix. 1907.— Wing 76, 78; tail 

 64, 66 ; bill 20, 22 mm. 



Nos. 530, 561. ?? ad., Jamarysinho, 9, 17. ix. 1907.— Wing 79—80; tail 

 68—70; bill 21 mm. 



" Iris brown, feet plumbeous or blackish, bill black." 



Identical with examples from the Tapaj6z. The original locality requires 

 confirmation, for in recent years the bird has not been found near the town of 

 Pard. 



229. Hjrpocnemis cantator peruvianus Tacz. 



IFoTinicarius Cantatirr (sic !) Boddaert, Tahl. PI. eiil. p. 44 (1783. — based on " Le Carrilloneur, de 



Cayenne," D'Aubentoa, PI. enl. 700. fig. 2 : Cayenne).] 

 Hypoenemis ennlalor, pernriinius Taczanowski, Orii. Peroti ii. p. CI (1884. — Yurimaguas, North 



Peru) ; Hellmayr, Noc. Zool. xiv. 1907. p. 377 (Humaytha). 

 B. cantator (not of Boddaert) Pelzeln, l.r. p. 87 (part. : Villa Maria, Engenho do Gama, Matto- 



grosso ; Borba, Rio Madeira). 



Nos. 262, 280, 369. JcJad., S imm., Calama, 24, 27. vii., 11. viii. 1907. 

 "Iris brown, feet plnmbeous, bill black, lower mandible greyish." — Wing 54i — 55 ; 

 tail 38—42; bill 14i— 15 mm. 



Nos. 222, 261. ??, Calama, 14, 24. vii. 1907.— Wing 53, 54; tail 37, 40; 

 bill 141, 15 mm. 



No. 982. 3 perad., Marnins, Rio Maehados, 8. vii. 1908.— Wing 56i ; tail 

 40J ; bill 14J mm. 



No. 983. ? ad., Marnins, 8. vii. 1908.— Wing 55 ; tail 39 ; bill 14^ mm. 



In the coloration of the upper parts — viz. large white dorsal patch, inter- 

 scapulars coarsely spotted with black and distinctly edged with white — the adult 

 males agree perfectly with a very large series from North-Eastern Peru, TeffS, 

 Mattogrosso, and Itaituba (R. Tapajdz). As a rule, specimens from Mattogrosso, 

 Calama, Marnins, Rio Juruii, and East Bolivia (Yuracares : D'Orbigny coll.) have 

 the flanks paler ochraceous, but several skins from Pebas (Pern) and Tefi'6 are not 

 different in this respect.
