Gaylord took a set of 3 fresh eggs near Pasadena, June 26 ('94) which 

 is also exceptional in being so late. Full sets are of 2 to 4 eggs, us- 

 ually 3. 



274 — 7 1 J. Heleodytes brun7ieicapilhis. (Lafr.). 



Cactus ^Vren. 

 Common resident locally on cactus covered washes in the mesa 

 regions. Breeds mostly in April, but I took a set of 5 fresh eggs near 

 Pasadena, March 18 ('92) and a set of 4 fresh eggs in the same local- 

 ity June 28 ('92). Full sets are of 4 or 5 eggs, sometimes 6. M. L. 

 Wicks, Jr., took a set of 7 fresh eggs near San Gabriel, May 25, ('89). 



275 — 7/5. Salpinctes obsoletus (Say). 



Rock Wrer). 

 Common winter visitant along dry washes, and toletably common 

 throughout the year in certain limited localities from the coast to the 

 highest mountains. I look nearly fledged young near the summit of 

 Mt. Waterman (8500 feet) on July 20 ('95). 



'276 — 717b. Catherpes mexicamis punctulatus Ridgw. 

 Dotted Canon "Wren. 

 Tolerably common resident in the mountain camons up to 6000 

 feet. Breeds in the rockiest and steepest canons usually in the neigh- 

 borhood of a stream. I took a set of 5 eggs, incubation advanced, in 

 the Arroyo Seco Canon north of Pasadena, May 5 ('94) and a set of 6 

 fresh eggs in the same locality, June 23 ('93). These probably indi- ■ 

 cate the extent of the breeding season. Sets are of 5 to 7 eggs. 



277 — 7iga. Thryoihorus bewickii spilurus (Vig.). 



Vigors's Wren. 

 Abundant resident of brushy mountain sides, the majority de- 

 scending in winter to the foot-hills and mesas. Full-fledged young 

 appear commonly by the middle of May, so that nesting probably be- 

 gins early in April. R. Arnold took a set of 4 fresh eggs near San 

 Fernando, June 7 ('96). 



278 — 721a. Troglodytes aedon parkinanii (Aud.). 

 Parl<:man's Wren. 

 Resident throughout the year, but much less common in winter 

 than in summer. Occurs from the lowlands to the highest mountains. 

 Generally found in wooded localities, where it breeds iu May. Ex- 

 treme nesting dates : Set of 8 fresh eggs taken by me near Pasadena, 

 April 20 ('95}., and a set. of 7 fresh eggs taken by H. A. Gaylord in the 

 West Fork of the San Gabriel Canon, June 18 ('93). Sets are of 5 to 

 9 eggs, usually of 7 or 8. 



279^722a. Troglodytes hiemalis pacificus Baird. 

 Westerr) Winter Wrer). 

 So far^ detected in small numbers during the winter only, in a very 

 limited locality in the mountains north of Pasadena. I have secured 

 specimens by Oct. 23 ('97), and and none later than Jan. 25 ('96). 

 The Arroyo Seco and Millard's Canons, and Mt. Wilson, are the only 

 localities where they have been discovered.
