the cafion streams, particularly in the elevated ‘parks,’ thus occupying a region intermediate 
between that of the Rocky Mountain Hermit-Thrush (T. auduboni) of the Pine-region, and that of 
the Tawny Thrush (T. fuscescens) of the lower valleys." 
During the Death Valley Expedition, Dr. Fisher says that this Thrush was reported by | 
Mr. Belding as common in the Yosemite Valley in California in June, and Mr. Nelson secured a 
female on the northern end of the Paramint Mountains on the 186 of May (N. Amer. Faun, 
no, 7, p. 145). 
The Olive-backed Thrush is only known as a migrant in the following States :—Illinois 
(Ridgway, Ann. Lyc. N. Y. x. p. 865) ; Ohio (Oberholzer, List B. Wayne Co. p. 338) in October, but 
not observed in spring; Indiana, spring and autumn migrant in Carroll Co., but not common 
(Evermann, Auk, vi. p. 31); Iowa, spring migrant (Jones, Auk, xii. p. 124) ; Western Missouri, 
spring migrant (Scott, Bull. Nutt. Orn. Club, iv. p. 140). Specimens procured in spring are in 
the Henshaw Collection from Washington, D.C., Illinois, Virginia (Gainsville, Prince William Co.) 
and a large series from Denver and Colorado Springs in Colorado. 
No specimens are in the British Museum from any of the South-eastern or Gulf States, but 
the species has been recorded from Roane Co., in Tennessee, as having been once seen by 
Mr. Fox on the 26th of April, 1885 (Auk, iii. p. 215). In Florida it is said by Mr. Scott to be 
rather common at Key West in April and May (Auk, vii. p. 119), and in the Caloosahatchie Region 
it is known as a spring and fall migrant (Auk, ix. p. 214). А specimen from Bermuda, collected 
by Captain Savile Reid, is in the British Museum. Іп Cuba the species is an accidental visitor 
(Cory, Auk, iii, p. 2). ј 
Returning to the continental range of the species, we learn that in Texas it is generally not 
rare during migration (Nehrling, Bull. Nutt. Orn. Club, vii. p. 7). It has been observed asa 
migrant near San Antonio by Mr. Attwater, and in the Salvin-Godman Collection is a specimen 
obtained by Mr. F. B. Armstrong at Corpus Christi in October. In Western Texas Mr. Lloyd 
says that it was noted by him as a fall migrant; rare in Tom Green Co., and not observed in 
Concho Co. (Auk, iv. p. 208). In New Mexico Mr. Henshaw states that it was fairly numerous in 
the autumn, arriving about Sept. 19 (Auk, ii. p. 330). 
The occurrence of T. swainsoni in Mexico has hitherto lacked confirmation, though Dr. Sclater 
has recorded the species (s. n. Turdus minor) from Orizaba (P.Z.S. 1857, р. 212), and Lawrence 
(s. n. T. swainsoni) from Tehuantepec (Bull. U.S. Nat. Mus. iv. p. 11). Messrs. Salvin and Godman, 
however, have received undoubted specimens of this Thrush from Mr. W. B. Richardson, from San 
Cristobal in Chiapas in April, and from Jitotol in the same province, procured in May. 
In Guatemala it has been recorded by Count von Berlepsch as having been found by Sarg 
at Coban, and a specimen is now in the Salvin-Godman Collection. Carmiol has sent others 
from Barranca, Frailes, and Cervantes in Costa Rica (Lawrence, Ann. Lyc. N.Y. ix. p. 91), and 
Mr. Rogers procured the species in the Irazu district (Salvin and Godman, Biol. Centr.-Amer., 
Aves, i. p. 11). Mr. Cherrie also records a specimen as having been obtained by Señor S. Alfraro 
near San José on the 7th of November, 1867 (Auk, vii. p. 337). It had already been recorded 
from Costa Rica by Von Frantzius (J. f. O. 1869, p. 289). 
In Nicaragua, Mr. Richmond noticed it on the Escondido River on the 3rd of October, 
and saw a large flock on the 14th of the same month (Proc. U.S. Nat. Mus. xvi. p. 482). 
M‘Leannan procured it at Lion Hill in Panama (Lawrence, Ann. Lyc. N.Y. viii. p. 7), and Hughes 
at Paraiso (Salvin and Godman, £. c. p. 11). 
In Colombia it would appear to be common in winter, as several Bogotá skins are in 
the British Museum, and Salmon met with the species at Medellin (Scl. & Salvin, Р. 2. S. 1819, 
p. 491).
