(192. Campylorhamphus trochilirostris procurvoides (Lafr.). 
Xiphorhynchus procurvoides Lafresnaye, Rev. Mag. Zool. (2) ii. p, 376 (1850.—Cayenne). 
Xiphornis procurvoides Hellmayr, Nov. Zool, xiv. p. 367 (Borba). 
X. trochilirostris (nec Licht.) Pelzeln, J.c. p. 44 (part. : Borba), 
Right bank : Borba (Natterer, Hoffmanns). 
Thanks to the courtesy of Dr. von Lorenz, I now have, in addition to the adult 
female out of Mr. Hoffmann’s first’ Madeira collection, three more specimens from 
Borba (Natterer coll.) before me, and can state that the supposed differences noticed 
by me /.c. have no real existence.. Two of the skins show slight blackish edges to 
the pale shaft-streaks on the foreneck and chest, but the third (Vienna Museum, 
No, 15914, ¢ ad., Borba, April 8, 1830) has no traces thereof, agreeing in this 
respect with the series of C. ¢. procurvoides from Cayenne and British Guiana. The 
olive tint of the lower plumage is not a constant character either, two of Natterer’s 
examples being even more strongly tinged with rufescent underneath than some of 
the Guianan ones. Moreover, in all principal! points, ¢.e. narrow buff shaft-lines on 
the head, immaculate dark brown back, deep rufous wings and tail, etc., etc., the 
Madeira birds are exactly similar to the latter. 
The geographical variation of C. trochilirostris not having been well understood 
hitherto, I think, a few words about the conclusions arrived at by studying a large 
amount of material may be welcome to ornithologists. The following races appear 
to be easily recognizable :— 
(a) C. trochilirostris trochilirostris (Licht.). 
Dendrocolaptes trochilirostris Lichtenstein, Abhandl. Akad. Berlin a. d. Jahren 1818-19. p. 207. 
pl. iii, (1820.—in Brasiliae provincia Bahia” ; cf, lc. 1820-21. p. 263). 
Hab. Kastern Brazil: Bahia (Sellow, Robert, etc.). 
Characters. Back “ wood-brown” or “cinnamon-brown” (Ridgw. Nomencl. iii. 
figs. 19, 20), with sharply defined buff or whitish shaft-stripes (never margined with 
blackish); crown and nape darker “ wood-brown,” marked with large, rounded, 
buff stripes, surrounded by a narrow blackish brown edge at the tip; ramp, upper 
tail-coverts, wings, and tail clear cinnamon-rufous. Throat white, the feathers of 
the lower portion narrowly fringed with brown; remainder of lower parts pale 
‘‘ wood-” or “cinnamon-brown,” covered with broad, whitish or buff shaft-stripes, 
laterally never edged with blackish ; lower abdomen and under tail-coverts uniform 
immaculate pale brown. Bill clear red. 
Wing 93—102 ; tail 82—90; bill 58—64 mm. 
Material. Twenty specimens from Bahia, only one of them (¢ ad., Lamarao, 
Bahia, A. Robert coll., No. 1549) sexed. 
(4) C. trochilirostris venezuelensis (Chapm.). 
Xiphorhynchus venezuelensis Chapman, Bull. Amer. Mus. N.Y. ii. p. 156 (1889.—Venezuela : types

Station (McLeannan ; fide Chapman).

Rio Negro, but these specimens are no longer to be found in the Vienna Museum.
