Hab. Mexico, Socorro Island (Grayson 1). 
Of this species, which Mr. Lawrence! says is so distinct from all others of the 
genus that no comparisons are necessary, we have never seen specimens. From the 
description it would seem to be allied to the H. redivivus section of the genus, in which 
the plumage is unspotted. Grayson, to whom the credit of the discovery of the 
species is due, found it during his expedition to the island of Socorro, and in his paper 
on the birds of that island has given the following note respecting it ?:— 
** Not very abundant, but seems to be well distributed over the island. It has all 
the characteristics of the true Mocking-bird in its habits (Mimus polyglottus). Of 
solitary disposition, it attacks every bird of its own species that approaches its usual 
haunts. 
“One took up its quarters in our camp, and was certainly the tamest bird of this 
genus I ever saw; he appeared to take pleasure in our society, and attacked furiously 
every bird that came near us. He doubtless regarded us as his own property, often 
perching upon the table when we were taking our meals and eating from our hands, 
as though he had been brought up to this kind of treatment; at times ascending to 
the branches over our head, he would break forth into loud and mellow song, very 
Thrush-like. In the still hours of the night, while roosting in the branches near us, 
he would sometimes utter a few dreamy notes, recalling to mind the well-known habits 
of the true Mocking-bird.” 
MIMUS. 
Mimus, Boie, Isis, 1826, p. 972. (Type Turdus polyglotius, Linn.) 
With the single exception of M. polyglottus, all the species of this genus are found 
in South America, their distribution over the southern continent being almost universal, 
extending from the northern shores to Patagonia, and including the greater Antilles 
and the Galapagos Islands. The common North-American species M. polyglottus is 
found throughout Mexico to the isthmus of Tehuantepec, where its place is taken by 
MM. gilvus, a species, under slightly varied plumage, extending through Yucatan, 
Guatemala, and Honduras to Colombia, Venezuela, and Guiana. 
In introducing the generic name Mimus, Boie gave no characters, merely men- 
tioning the type species. This want is fully supplied in works on North-American 
ornithology *.
