Z. 1840, p. 103), a species Sclater considers, with Lafresnaye himself, to be a Scytalopus (Cat. Am. B. p. 168), and to belong to the Pteroptochidce. Though not altogether satisfactory, I must say I think Lafresnaye's description suits the Scytalopus better than the Henicorhina, no mention whatever being made of the conspicuous markings on t'ne sides of the head in the present bird. Taking Baird's list of localities, the evidence afforded by the distribution of this Wren is all in favour of there being but one species. 9. CISTOTHORUS ELEGANS, Scl. & Salv. 1; Baird, Rev. Am. B. p. 146. Bugaba. A single specimen in abraded plumage seems to belong to this species. The bill, however, is very robust, and the head exhibits none of the longitudinal light markings to be seen in C. elegans. As regards the colouring of the lower back and uropygium, the chief distinguishing character between C. elegans and C. palustris, this skin agrees very fairly with the former. The specimen is not in a condition good enough to enable me to determine it satisfactorily. 10. POLIOPTILA SUPERCILIARIS, Lawr.; Baird, Rev. Am. B. p. 71. Bugaba. Mniotilta varia. Calovevora; Cordillera del Chucu ; V. de Chiriqui. 11. PARULA INORNATA, Baird, Rev. Am. B. p. 171. Boqueti de Chitra ; V. de Chiriqui. 12. PARULA GUTTURALIS (Cab.), J. f. Orn. 1860, p. 329 ; Baird, Rev. Am. Birds, p. 172. V. de Chiriqui. Arce's last collection contains three specimens of this beautiful species, which are the first I have ever seen. According to Arce's dissections, both sexes have the interscapular region black ; but in the female this character is neither so extensive nor so regular in form as in the male.
