Fam. CORVIDA. 
*9. Calocitta formosa (Sw.). 
This elegant jay is quite common around San Juan. I noticed that 
the natives here, as in Costa Rica, ascribe to it the power of speaking, 
although I never saw one which had acquired that accomplishment. 
Fam. TYRANNIDZ. 
10. Myiozetetes texensis (Giraud). 
Abundant. Apparently gregarious, being almost always found in 
small flocks. A lively and interesting bird, sure to attract the attention 
of the collector by its bright color, activity, and peculiar cries. The 
latter I can compare to nothing but the cry of a little chicken in distress. 
Itis found both in the woods and more open country, seeming to prefer 
isolated trees in the vicinity of water. 
Three specimens secured. 
*11. Rhynchocyclus cinereiceps Scl. 
Iris white. Only one specimen. 
*12. Pitangus derbianus Kaup. 
Abundant. One of the most conspicuous birds of the region. It is 
most frequently seen on the margin of the water perching on some low 
branch awaiting its insect prey. Its cry is extremely harsh and monot- 
onous, proving an annoyance to one listening for the notes of other 
birds. It is, moreover, of a decidedly quarrelsome disposition, even 
more so than the rest of its family. Two specimens. 
13. Megarhynchus pitangua (Linn.). 
Not so common as the last. Habits much the same, but it does not 
show such a marked preference for the vicinity of the water. 
Two specimens secured. 
*14. Myiarchus nuttingi Ridgw. 
Common, but rather solitary in its habits. It is usually seen sitting 
‘quietly on a low limb in the thick woods. It is quieter than many of 
its kind. 
Three specimens. 
15. Tyrannus melancholicus satrapa (Licht.). 
Apparently rare. One specimen secured. 
16. Milvulus forficatus (Gm.). 
This graceful Flycatcher is more abundant in the vicinity of San 
Juan than in any other region in which I have collected. 
It is gregarious in its habits, being usually found in flocks of from six 
to ten. It is much more silent than is usual among the Flycatchers, 
and more timid and difficult to approach than any that I can think of. 
I had ample opportunity to observe this bird, and was struck with
