another. Collectively they represent a form which may readily he 

 (listing'uished from E. h. hicolor of the Bahamas hy decidedly .shorter 

 wing and tail and brighter olive or olive-greenish upper parts, and 

 from E. h. marcJu'l of Jamaica, Barbados, and Grenada by having, in the 

 adult male, the black of the chest extending over the In-east (sometimes 

 over the belly also) and without abrupt posterior outline. 



When a sufficient number of specimens from each island shall have 

 been brought together and carefully compared, it is almost certain 

 that several local forms will have to be recognized. The existence of 

 these is clearly indicated by the meager series before me, specimens 

 from different islands, notably those from Santa Lucia and St. Thomas, 

 being uniformly peculiar in certain features of coloration. Thus the 

 three adult males from Santa Lucia are browner than those from 

 other islands, the black on anterior under parts very restricted (but 

 of quite difl'erent form from that of E. h. niarchii., the remaining under 

 parts being peculiarly dark and brownish. The four adult males from 

 St. Thomas have the "solid" portion of the black chest as restricted 

 as in E. h. march il^ but it merges into the lighter-colored posterior area 

 by intervening blackish feathers with pale margins, thus producing" a 

 somewhat streaked appearance. Were it certain that the specimens 

 examined are really fully adult birds, I would not hesitate to separate 

 the lairds from Santa Lucia and St. Thomas, respectively, as local 

 forms; but there is a possilnlity they may not yet have acquired the 

 perfect plumage of the adult male. 



^^'^ith four adult males from Venezuela, I am unable to distinguish 

 any peculiarities, as compared with Antillean specimens, except that 

 the tail averages decidedly shorter. In coloration they appear to be 

 quite identical with specimens from Porto Rico and some other Carib- 

 bean islands. 



An adult, or nearly adult, male from Bogota, Colombia, in the col- 

 lection of the American ^Museum of Natural History (No. 41327) is 

 scarcely to be distinguished from E. h. imn'chii in color, the black of the 

 anterior under parts extending no farther back than the chest and 

 ending (juite abruptly. Dr. Sharpe, however, describes an adult male 

 from Colombia as having '"the l)lack extending down the center of 

 the abdomen, but not reaching to the vent,"" and therefore I am dis- 

 posed to regard the specimen mentioned alcove as not in full plumage. 

 A good series of specimens, however, will be necessary to establish 

 the relationship of the Colombian bird. The American Museum speci- 

 men measures as follows: Wing, 55.88; tail, 38.86; exposed culmen, 

 9.40; depth of bill at base, 7.37; tarsus, 18.03; middle toe. 13.46.
