MOMOTUS LESSONI, LeS3. 



Chontales {Belt). 



Prionirhynchus platyrhynchus, Leadb. 

 Chontales {Belt). 



This species was also procured on the Blewfields River by Mr. 

 Wickham. 



Prionyrhynchus carinatus, Du Bus. 



Scl. Cat. Am. B. p. 263. 



Chontales (Belt). 



Quite recently two Guatemalan skins of this rare species have 

 come into our possession, though it entirely escaped my obser- 

 vation during my stay in that country. Mr. Belt's collection 

 contains a single example, so that in Chontales we find both 

 species occurring together. P. carinatus was obtained near 

 Lake Yojoa by Mr. G. C. Taylor, and is evidently a species of 

 much wider northern range than its congener, which, common 

 in Costa Rica and southwards to Panama, has not been known 

 to pass the present district. The two, though strictly congeneric, 

 are easily recognizable as species, P. platyrhynchus having the 

 whole head and neck rufous, these parts being green like the 

 back in P. carinatus. 



Ceryle alcyon (Linn.). 

 Chontales (Janson).

I am at a loss to discover any really tangible characters 

 whereby to distinguish the Central-American bird called T. te- 

 nellus by Cabanis (described from an immature male !) from
