much brighter and deepei vinaceons, and by their larger beak. The upper 

 surface is exactly of the same toue as iu the Borba and Para specimens. 



There is no constant difference between F. a. anulis and F. a. crissalis in the 

 development of the white loral spot. 



The rauge of the two forms is accordingly as follows : 



(a) F. a. anulis (Lafr. & D'Orb.). Eastern Bolivia : Ynracares, Chiquitos 

 (D'Orbigny), Yungas (Rusby). Pern: Chanchamayo (Sclmuke coll. — Mus. Triug.), 

 Sarayacu on the Ucayali (Whitely), Chyavetas, Xeberos (Bartlett), Huambo 

 (Stolzmaun), Shanusi, near Yurimaguas (Garlepp), Iquitoa (Whitely). Brazil : 

 Salto do Girao (Nattercr) and Borba, Rio Madeira (Nattercr, llolfmanns) ; Telle 

 Rio Solimoens (Hoffmanns) ; Para (Wallace, Baraquin).* 



(Jj) F. a. crissalis (Cab.). 



Myrmornis crissalis Cabanis, Journ. J. Ornith. 1861, p. 96. (Roraima, Brit. 

 Guiana). — Cayenne ; British Guiana : Roraima (Schombargk), Camacusa, Rio 

 Carimang, Rio Takutu (Whitely). 



118. Corythopis torquata anthoides (Pnch.). 



Cf. Nov. Zool. xii. 1902. p. 293. 



Corythopis anthoides Pelzeln, Znr Oniilli. Brasil. ii. 18G8. p. 92 (Borba). 



No. 1187. ? ad., Humaytha, 30. viii. 06. '• Iris brown, feet grey, bill black, 

 below yellow." — Wing 63 ; tail 47 ; bill 14 mm. 



Agrees with a female from Cayenne in having the pileum olive-brown like 

 the back. 



110. Threnetes leucurus (Linn.). 

 Cf. tupra, p. 74. 



No. 1009. S ad., Humaytha, 28. vii. 06. " Iris black, feet greyish white, 

 bill black, below white at the base." — Wing 65 ; tail 35i ; bill 3U mm. 



No. 1018. ? ad., Humaytha, 30. vii. 06. " Iris black, feet whitish yellow, 

 bill black."— Wing 57 ; tail 33 ; bill 28 mm. 



Nos. 1312, 1319. ? ad., ? jun., Paraizo, 19, 28. x. 06. "Iris black, feet 

 yellow or pale grey, bill black." — Wing 61, 56 ; tail 35, 3H ; bill 30 mm. 



These specimens agree with those from Teffe, previously sent by Mr. Hoffmanns, 

 the sides of the belly and, iu the females, also the foreueck being distinctly 

 washed with pinkish buff, but the middle of the breast and abdomen are pure 

 greyish white, as iu typical birds from Surinam. 



In the adult c? 3 (from Humaytha, Teffe and Surinam) before me, only the 

 two outer pair of rectrices have black markings, while in the females the two 

 following ones are also more or less black on their basal half. The light portions 

 of the tail-feathers are always pure white. 



12n. Glaucis hirsuta (Gm.). 

 Cf. Nov. Zool. xiii. 19U0. p. 374. 



Nos. 1288, 1289. <? ? ad., Humaytha, 2 1. ix. 06. "Iris black, feet yellow, bill 

 black, below yellowish green." 



Nos. 1351, 1347. cT juv., ? imm., Borba, 17. xi. 06. " Iris black, feet greyish 

 yellow, bill black, below yellow." 



• Specimens from Eastern Ecuador in the liritisli Museum very likely represent a distinct form.
