is likewise much browner above, of a much duller yellow beneath, and 
the proportions are totally different. While G. speciosa has much the 
slenderest bill of any member of the genus (with the possible excep- 
tion of G. semiflava, which I have not seen), G. bairdi has this member 
much larger than any of its congeners except G. rostrata. In the latter 
the bill is longer but less robust, a striking character of the present 
Species consisting in the distinctly curved culmen, with the basal por- 
tion prominently ridged and unusually elevated, thus calling strongly 
to mind a characteristic feature of Helonwa swainsoni Aud. 
The species is based on three examples, two males and a female, as 
follows : 
No. 91150, 3 ad., Los Sabalos, Nicaragua, May 15, 1883; C. C. Nutting. 
No. 91151, 3 ad., Los Sabalos, Nicaragua, May 2, 1883; C. C. Nutting. 
No. 91152, ? ad., Los Sabalos, Nicaragua, May 14, 1883; C. C. Nutting. 
NOTE.—Since the above was written specimens have been sent to Mr. 
Osbert Salvin, who writes thus respecting them: “ Geothlypis bairdi is 
very cluse indeed to G. semiflavé of Ecuador. The colors are slightly 
more olivaceous.” It is not likely, however, that they are identical, 
geographical considerations decidedly favoring their distinctness.—R. R. 
Common. The three specimens secured were all shot in an open, 
marshy piece of ground near the river. This ground is covered with 
water in the rainy season, and a luxuriant growth of tall, coarse grass 
and weeds in the dry season. It is in these weeds that G@. bairdi prefers 
to make its home. Song, loud, clear, and sprightly. Habits very simi- 
lar to those of G. trichas. 
*9. Basileuterus leucopygius Scl. & Salv. 
Common. Always seen near running water, where they flit along the 
bed of the stream in the same manner as do our Cinclide@. One speci- 
men. 
Fam. CQAREBID A. 
10. Ccereba cyanea (Linn.). 
Apparently not common. Only one specimen secured. 
Fam. TANAGRIDA. 
11. Tanagra cana diaconus (Less.). 
Apparently not very common. One specimen seen but not secured. 
12. Ramphoccelus passerinii Bp. 
Very abundant. This richly colored Tanager is one of the most con- 
spicuous birds at ‘Los Sabalos.” It seems to be gregarious, and evi- 
dently prefers marshy ground. There are large tracts of land near the 
river which are covered by a luxuriant growth of a large-leafed plant 
{probably a Caladium), and R. passerinii can almost always be seen ap- 
parently feeding on the species of insects peculiar to these plants. 
I have never heard these birds utter any note other than a short 
chirp. 
Thirteen specimens. Iris brown. Bill light blue.
