table of measurements of specimens examined, a supplementary 

 description of Hylocichla f. salidcola ■ as Mr. Ridgway's descrip- 

 tion is in some ways decidedly unsatisfactory. 



Upper parts olivaceous-tawny, "russet olive" particularly on crown, 

 nape, bacli, scapulars and tail, most tawny on the rump. Under parts : 

 throat almost immaculate and unmarked, breast suggesting szvainsonii, 

 dark olivaceous-bulf, not light tawny buff like fuscescens, quite heavily 

 marked with blunt arrow shaped spots of fuscous, especially in the fall, 

 unlike the brownish more penciled markings of ^.•JceiceKs ; lower breast 

 and belly white, tinged strongly with olivaceous on the sides and flanks; 

 wings olivaceous-lawny "russet olive" with the greater, middle and 

 primary coverts tawny ; cheeks tawny, but not lores, as in sTuainsonii ; 

 upper mandible very dark brown, under horn color, tipfed -Mith bro-ivn as 

 m swainsonii, unlike/«.?ce,?c(;«5, whose under mandible is untipped in the 

 spring and lightly if at all in the fall. 



Ridgway states that the breast in adult spring specimens " is 

 only faintly or not at all spotted with darker," which is hardly so, 

 I think even in the very specimens he examined, this marking of 

 the breast being one of the characteristics of salicicola ; and his 

 measurements, proving the race "averaging decidedly larger" 

 XX^'i.^ fuscescens, do not agree with mine taken from a much larger* 

 series than he tabulates, showing the males of salicicola to be only 

 slightly larger, and the females slightly smaller than fuscescens, or 

 no real material difference in size. 



For the use of specimens for comparison thanks are due to

 National Museum ; Mr. Witmer Stone of the Academy of Nat- 

 ural Sciences, Phila. ; Dr. Walter Faxon, Museum Comparative 

 Zoology, Cambridge; Mr. William Brewster of Cambridge;
