Catherpes mezicanus, var. conspersus (I, \'-'>\>). Nmnerous specimeus

 Henshaw, establisii tl j fact of >;reat uniformity in the characters of this race, and 

 its distinctness frou) var. iticrlrdinis. On pai;e l.'?"J "it is noticed that it is a re- 

 markable fact that this northern race should be so much smaller than the Mexican 

 one, especially in view of the fact that it is a resident bird in even tlie most 

 northern ])arts of its ascertained iiabijat." As we find this peculiarity exactly 

 paralleled in the T/iri/of/ionm hijoriciniixs of the Atlantic States (see below), may 

 not those facts ])oint out a law to the eflect that in species which beloni.' to essen-

Dr. Cooper nK>t with two sj)eeimens of this species in California in 1S7l'; one 

 about twelve miles back of Snn Diego, the other the same distance back of San 

 Buenaventura, and both at the foot of lofty, rugged mountiiins. Their song ho 

 compares to loud ringing laughter ; it is so shrill as to be heard at (piite a distance, 

 and seems as if it nnist bo produced by a much larger bird. 



Thryothorus ludOVicianus (I, 1 ll.'). Specimens of this species i ., 



Fla., are nnieh darker colore<l th.-m those from the Middle States (Maryland, Illi- 

 nois, and southward), as might be expected ; but very sti'angely, they are also 

 niuch largci". In colors they very nearly resemble var. hcrlHinluri, from the Lower 

 Rio Grande. 



A specimen in Mr. Ridgway's collection (No. I,8(i4, January 9), from Miami, 

 Fla., compares with one from Southern Illinois (No. \,(\iyl, Mt. Carmel, .lanuary, 

 1871) as follows: — 



In coloration they are more nearly alike, the Florida si)ecimen being hardly 

 appreciably darker on the upper surface, though the lower parts are much deei)er 

 ocin-aceous, almost rufous. The Illinois specimen is deep ochraceous beneath, 

 just about intermediate between Maryland and Florida specimens. Another 

 Florida specimen (No. <)2,7.'>.'^, Mus. S. I. ; C. J. Maynard) measuns : wing, L'.."»0 ; 

 tail, 2.40 ; culmen, .8.").
