SmaU CuculinsB (length about 250 mm.) resembling the genus 

 Piaya but differing in relatively much shorter tail (only one and a half 

 times as long as wing), relatively much shorter tenth (outermost) 

 primary (decidedly less than half as long as longest primary), and 

 much smaller size. 



o One specimen, from Puerto Cabello, Venezuela. I liave not seen an undoubted 

 male of this species, which seems to be very rare in collections. The only other 

 example of the species examined is one without sex determined, from Cienega, Santa 

 Marta, Colombia, which measures as follows: Length (skin), 265; wing, 116.5; tail, 

 143; ; exposed cuhnen, 25.5; tarsus, 25; outer anterior toe, 19.5. 



Two specimens (sex not determined) in the collection of the Academy of Natural 

 Sciences, Philadelphia, have been measured for me by Mr. Stone, the measurements 

 being as follows: No. 20116, "Lima, Peru." Wing, 109; tail, 139; exposed culmen, 

 27; tarsus, 25. No. 20120, "South America. " Wing, 110; tail, 137; exposed culmen, 

 28; tarsus, 25. 



^ The occurrence of this species in Panama is possibly doubtful, since it is 

 omitted from the Biologia Centrali- Americana.
