OCHTHORNIS LITTORALIS (Pelzeln): Natterer’s Water-tyrant 
Elainea littoralis PELZELN, Zur Ornithologie Brasiliens, pt. 2, 1868, pp. 108, 180 
(Cachoeira Guajard—guacti, Rio Mamoré; Cachoeira de Bananeira and 
Borba, Rio Madeira). 
SPECIMENS COLLECTED 
1 ad. o&, Brazil, Camanaos, Rio Negro, December 23, 1930. 
1 ad. 2, Brazil, Sao Gabriel, Rio Negro, January 14, 1931. 
lad. 9, Venezuela, Playa de Candela, Brazo Casiquiare, February 8, 1931. 
lad. 9, Venezuela, Brazo Casiquiare near Cafio Mabinagui, February 20, 1931. 
All four specimens are in very abraded feathering; the male has the 
tail worn to a stump (possibly partly owing to shot?) not much more 
than half its normal length. There appears to be great variation in 
the stage of plumage at the same time of the year as three adults from 
the Rio Purts, Brazil, taken between December 24 and February 7 
are in fairly fresh plumage. 
MACHETORNIS RIXOSA FLAVIGULARIS Todd: Northern Fire-crowned Tyrant 
Machetornis rizosa flavigularis Topp, Ann. Carnegie Mus., vol. 8, 1912, p. 210 
(Tocuyo, State of Lara, Venezuela). 
SPECIMEN COLLECTED 
lad. ¢, Venezuela, Soledad, Anzodtegui, June 11, 1931. 
The single example collected is in worn plumage. According to 
the collector’s notes the bird was in breeding condition. 
MUSCIVORA TYRANNUS TYRANNUS (Linnaeus): Southern Fork-tailed Flycatcher 
Muscicapa tyrannus LINNAEUS, Systema naturae, ed. 12, vol. 1, 1766, p. 325 
(Surinam). 
SPECIMENS COLLECTED 
lad. 2, Brazil, Santa Isabel, Rio Negro, October 10, 1930. 
1 ad. o’, Venezuela, San Antonio, Upper Orinoco, March 8, 1931. 
lim. 2, Venezuela, right bank Upper Orinoco, opposite Corocoro Island, March 
12, 1931. 
The male is in badly abraded plumage. All three specimens show 
the dark dorsal color of the southern race, which comes to our area as 
a migrant. 
The type locality of this race was cited as Cayenne by Berlepsch 
and Hartert in 1902 (Nov. Zool., vol. 9, p. 52) but more recently has 
been restricted to Surinam by Zimmer (Amer. Mus. Nov., No. 962, 
1937, p. 1), the latter seeming from the record to be the proper action. 
In the original description Linnaeus gives the habitat as “in Canada, 
Surinamo.” He refers to Brisson’s Muscicapa Tyrannus cauda 
bifurca, that author stating that he had seen specimens from Canada 
and Cayenne. Linnaeus, however, seems to have seen some material 
of his own, as he goes on to list two varieties or kinds as Surinamensi 
and Canadensi with color characters for each. He does not mention 
Cayenne.
