A2 Cory on West hidian Birds. [January 



fill exiimination and comparison of the material now before me 

 shows that the variation in color of specimens from different 

 islands is not at all constant, and I am forced to tlie conclusion 

 that the supposed races albiveniris and rufiis as described by 

 Mr. Lawrence and myself, are untenable. 



It is evident tliat the species in question should be separated 

 generically from Cichlherniinia^ as ]\Iargarops cannot be used, 

 the type being given as fuscatus. I therefore propose the name 

 of Allenia^ in compliment to Dr. J. A. Allen of New York, 

 for the new genus.

1 have been fortunate in being able to procure a very large 

 series of Cichlherminia fuscata and C. densirostris from the 

 Antilles, numbering in all over two hundred specimens, and a 

 careful examination of this material gives the following results. 



1. That there is a gradual change in color from a light brown 

 form in the extreme north (Inagua, Bahamas) to a dark brown 

 form with slightly different markings in the extreme south (St. 

 Lucia). 



2. That the change in color is so gradual that specimens from 

 approximate islands cannot be separated. 



3. That there is no positive line of demarcation, and that the 

 two forms should be separated subspecifically if at all. 



It is claimed that birds from the Lesser Antilles have the irie 

 yellow, wliile in those from Porto Rico, Inagua and some of the 

 northern islands it is white. According to the notes given by 

 tny collectors this does not seem to be a constant character, as the
