specimens. In his later work this separation is not confirmed S; but Mr. Lawrence ^^ 

 refers Tehuantepec specimens to the long-tailed race, if such it is, under the name 

 Mimus polyglottus, var. caudatus. Our Oaxaca specimen, however, has a shorter tail 

 than one from Villa Alta and another from Cape San Lucas in our collection ; so that 

 the length of the tail cannot be said to be a characteristic of western specimens. 



The well-known habits of this species are fully described in works on North- 

 American birds ^.

The name Turdus gilvus was bestowed upon a Guiana bird, which was also said to be 

 found in the warmer parts of South America ^ ; and Vieillot's plate of it ^ fairly represents 

 the bird found throughout the northern parts of South America and Central America 

 as far north as Guatemala. Several names have since been proposed for this Mimus ; but 

 the differences between birds from different localities seem hardly sufficient to justify the 

 retention of any of them. The bird found in Venezuela is perhaps the most distinct, 

 as it has the wing-coverts more broadly edged with ashy, and tipped more widely with 

 the same colour, than usual in Colombian and Guatemalan specimens ; but the latter 

 are not quite constant in this respect, and we think all ought to bear the same name. 

 Thus M. melanopterus^ of Venezuela, M. columbianus'^ of Colombia, and M. gracilis^ 

 of Honduras all become synonyms of M. gilvus.
