PYRGISOMA. 403 
Regarding the name Pyrgisoma xantusi proposed for this species by Mr. Lawrence, 
there can be little doubt it is synonymous with P. rubricatum. We have a typical 
specimen of the former before us which agrees with M. Boucard’s Atlisco example, 
which came from the same region as the types of the latter.

There has been a good deal of confusion respecting this species, which has at various 
times been called P. biarcuatum and P. kieneri, until it was described under its present 
title in 1868 by Sclater and Salvin and figured in their ‘ Exotic Ornithology’ *. 
From P. biarcuatum it may at once be recognized by the presence of a black pectoral 
spot, and the white circumocular region, especially below, is much more restricted ; 
moreover, there is a black rictal line not present in the allied bird. P. kieneri is 
larger, has no black rictal stripe, the white of the side of the face restricted to the 
lores, &c. 
P. cabanisi, so far as we know at present, is restricted in its range to the uplands of 
Costa Rica, where it would appear to be far from rare, and indeed probably as common 
a species there as P. biarcuatum is in Guatemala. Hoffmann obtained the first speci- 
mens, and sent them to the Berlin Museum’. It has since been secured by nearly 
every collector who has worked in Costa Rica.

* This figure does not represent the distribution of colour about the eye very accurately. Well-preserved 
specimens show a white triangular spot behind the eye and a broad black line proceeding from below the eye 
and surrounding the rufous ear-coverts.
