clining to orange along tomia; legs and feet black. Wing 2.75; tail 
2.35, culmen .62 (from extreme base), bill from nostril .35, width at base 
.o2, tarsus .68, middle toe .40. 
In coloration this species presents a remarkably close resemblance to 
E. flavescens Lawr. The breast, however, is paler and decidedly less 
fulvous, the yellow of the abdomen paler, the upper parts have less 
of a russet cast, and the wing bands are paler. Besides, it is consider- 
bly larger, the measurements of an adult male of ZH. flavescens being as 
follows: Wing 2.40, tail 2.05, culmen (from extreme base) .62, bill from 
nostril .35, width at base .28, tarsus .62, middle toe .35. 
10. Pittasoma michleri zeledoni, subsp. nov. 
Subse. co.—Adult ¢: Similar to P. michleri, but much larger, and 
with the head entirely black, except a few touches of chestnut on the 
auriculars. Wing, 4.35; tail, 1.60; culmen, 1.25; tarsus, 2; middle toe, 
1.25. 
Type, No. 91841, Rio Sucio, Costa Rica, 1881; J. Cooper, collector. 
The measurements of an adult male of P. michleri (No. 53778, Panama; 
McLeannan), are as follows: Wing, 4.05; tail, 1.35; culmen, 1.05; tar- 
sus, 1.85; middle toe, 1.10. In P. michleri only the pileum is uniform 
black, the entire cheeks and auriculars being chestnut, while the black 
of the chin, throat, and malar region is spotted with the same. 
11. Acanthidops bairdi Zeledon, MS. 
In the original description of this species (Proc. U. S. Nat. Mus., vol. 
4, p. 336) the writer accidentally omitted to credit the specific name to 
Mr. Zeledon. The oversight is much regretted, and the present oppor- 
tunity is taken to make amends. 
Besides the foregoing species, the following were contained in the 
collection received from Mr. Zeledon, all of which are included in that 
_ gentleman’s excellent list* of Costa Rican birds.
