This new species is dedicated to Mr. G. Frean Morcom, of 

 Los Angeles, California, to whom I am indebted for the privi-

 Museum by Mr. W. B. Judson. 



DESCRIPTION OF A NEW SPECIES OF 

 GYMNOSTINOPSy 



BY CHARLES W. RICHMOND. 



Among the birds obtained by Lieut. Michler's expedition 

 across the Isthmus of Panama, via the Atrato River, are two 

 specimens of Gymnostinops, labeled in Cassin's handwriting 

 " Ostinops guatimozinusr One is an adult female of the true 

 G. giiatimozimis, the other is an adult male of a species more 

 nearly related to G. tnonteziwice but quite distinct, and hitherto 

 unnamed. The male was apparently the only specimen before 

 Cassin when he reported on the Michler collection, as his remarks 

 here quoted indicate : " One specimen, labeled as a male, in the 

 collection of the expedition is distinct from any species in Acad, 

 coll. or that we find described, except as above \Ostinops guati- 

 mozinus Bonap.]. It is nearly allied to O. montezuma. of Mexico 

 and Central America, and O. bifasciatus of Northern Brazil, both 

 of w^hich are in the Acad. coll. and are distinct from each other. 



" The present bird differs from both of the above species in 

 being larger, darker colored, and having a lengthened almost 

 filiform crest. The bill also is disproportionately longer and 

 wider at base, with a rounded termination in front. It is not 

 without scruples that I apply the name above to this bird ; the 

 description by the Prince-Bonaparte, as cited, not being sufficient 

 or the recognition of any species nearly related to another." - 

 The collector's notes are then given as follows :
