Sept. oa BANGS — PANAMA BIRDS 25 
1900 
Myrmelastes intermedius (Cherrie). 
Four specimens, both sexes. ’ 
Myrmelastes ceterus’ sp. nov. 
Type (and only specimen in the collection) from Loma del Leon, Panama, 
& adult, no. 7323, coll. of E. A. and O. Bangs, collected March 30, 1900, 
by W. W. Brown, Jr. 
Specific characters.— Similar to WM. lawrencti Salv. and Godm. of Nicaragua 
and Chiriqui, except that the Panama form has white-tipped greater wing- 
coverts and rectrices, and much larger and more prominent concealed white 
patch on back. 
Color.— Adult male (type): black all over; wings rather brownish black; 
a large, concealed, white patch on back; wing-coverts broadly tipped with 
white and rectrices narrowly tipped with white; lining of wing mostly whitish. 
Measurements.— Adult male (type): wing, 73-; tail, 55.; tarsus, 30.4; 
exposed culmen, 18.2 mm. 
Remarks.— M. ceterus is the bird Lawrence described as A/yr- 
melastes corvinus from an immature male from Panama. Salvin 
and Godman, finding that the name corvinus had already been 
used in connection with A/yrmelastes, renamed the species /aw- 
rencii and described one of the Chiriqui examples from their col- 
lection. Now it appears that two species enter into the question — 
one inhabiting Nicaragua and Chiriqui, the other Panama, the 
Panama form (corvinus Lawr.= ceferus) distinguished by having 
white tips to the rectrices and greater wing-coverts and a prom- 
inent concealed white patch on back, the Nicaragua and Chiriqui 
form (/awrencit Salv. and Godm.) by having no white on wings or 
tail and the concealed dorsal patch almost obsolete. 
Dendrornis nana Lawr. 
Twelve specimens, both sexes. 
Picolaptes lineaticeps Lafr. 
One adult male. 
1 Ceterus — the other, that which exists besides.
