180 DENDROCOLAPTIDZ. 
Temascaltepec in the tableland of Mexico!, The description is very imperfect, but we 
think certainly refers to the bird subsequently described by Lesson as Dryocopus 
eburneirostris 4, The latter title, however, has been more frequently employed than 
the former, partly from the brevity of Swainson’s description, partly from the hybrid 
formation of his name.

D. eburneirostro affinis sed minor, rostro minore, maxilla nigricante, mandibula quoque interdum nigra, striis 
dorsalibus paucis et angustioribus: subtus magis rufescens, abdomine et tectricibus subcaudalibus vix 
striatis. Long. tota 9°0, ale 4:1, caude 3:4, rostri a rictu 1°3, tarsi 0-9. (Descr. maris ex San Pablo, 
Panama. Mus. nostr.)

The differences distinguishing this bird from D. susurrans of the island of Tobago 
and the northern portion of the continent of South America are very slight, and 
perhaps hardly of specific value, consisting as they do in the rather deeper tint of the 
fawn-coloured markings of the under surface and the more elongated stripes of the 
abdomen of the Central-American bird. A good deal of variation exists in individuals 
of both forms, but on the whole they seem to conform to these points of distinction. 
We confess at the same time that we are straining a point in admitting D. nana to be 
different from D. susurrans, and we do so with much hesitation. Mr. Sclater places 
the two birds under D. susurrans, while Mr. Elliot keeps them distinct, considering 
D. nana to be easily recognizable, which may be the case in the series examined by 
him, but is not so in ours. 
The range of D. nana has been traced to the north coast of Honduras }%, and thence 
southwards through Nicaragua, Costa Rica, and the State of Panama. All southern 
birds beyond this seem to be referable to D. susurrans. 
From D. pardalotus this species may be distinguished by its stouter bill; the 
markings of the breast, too, are less definite, the margins to the central stripes being 
not so black.
