Ob.i. — It is, porl'ps, probable that in Yucatan this race grades into the ^f. stoli<lu.<i (var. 

 s/iili(liis), .since there is a spociniou in the collcctiiMi from Merida (;)0,21.'?, .\pril 9, 1805, A. Schott) 

 wlucli .seems to be very nearly ititcniii'ili:itc in every way liciwcon the two. It has the very 

 l)lack bill, restricted rufous on inner webs of nvtrices, and pale yellow of lower parts of M. 

 sliiliilii.i, iind the brown pilevmi and more robust ])ro|iortions of irrifnbili.t. The si>ecinicn, how- 

 ever, is in poor condition, being of worn and faded plumage, and much distorted, so that its 

 true characters cannot be ascertained satisfactorily.
