Fam. TROGONID A. 
32. Trogon melanocephalus Gould. 
Common. I saw no other Trogon on the island. One specimen. 
Fam. CUCULIDA. 
33. Crotophaga sulcirostris Sw. 
Abundant. One specimen. 
Fam. PSITTACIDA. 
*34. Ara macao (Linn.). 
Common. No specimens. 
*35. Conurus holochlorus Scl. 
Extremely abundant. The number of these parrots to be seen around 
the lagoon is something almost incredible, and the air seems to fairly 
tremble with their cries. I do not remember seeing any other species 
of birds swarming in such numbers. Eight specimens. 
*36. Brotogerys tovi (Gm.). 
Abundant. Four specimens. 
*37. Chrysotis guatemale Scl, 
Common, more especially around the base of the voleano, where the 
dense, unbroken forests afford a quiet retreat. It is considered a good 
talker, and is frequently seen tame in the huts of the natives. Iris yel- 
low. Cere black. Five specimens. 
Fam. FALCONID A. 
*38. Rupornis ruficauda (Scl. et Salv.). 
Abundant. Three specimens. 
*39. Rosthramus sociabilis (Vieill.). 
Not common. Found on the lake shore, where it is usually seen hunt- 
ing for the small univalve shell which constitutes a large proportion of 
its food. Iris dark red. One specimen. 
*40. Busarellus nigricollis (Lath.), 
Rather common. Seems to prefer low, swampy country. Very easily 
approached. 
One specimen. Iris brown. 
Fam. COLUMBIDA. 
*41. Columba erythrina Licht. 
Common. Especially along lake shore. 
Three specimens. Iris yellow. Bill dull red. Legs and feet clearer 
red. 
“42. Melopelia leucoptera (L.). 
Not common. One specimen
