EMBERNAGEA. 413 



corylinis. Long, tota 5*0, alae 2-4, caudse 2*0, rostri a rictu 0'55, tarsi 0-9. (Descr. exempl. typ. ex 

 Bebedero, Costa Rica. Mus. nostr.) 



Eab. Mexico, Hamelula, isthmus of Tehuan tepee (Sumichrast^). — Costa Riga, Nicoya 

 (Arce ^, V. Frantzius ^). 



In our original description of this species we compared it with E. cMoronota, but we 

 now think that U. rufivirgata is its nearer ally. This is shown by the colour of the 

 stripes on either side of the vertex being dark rufous and not black ; but the stripes of 

 the head are much more conspicuous than in the allied form, and by this means 

 E. superciliosa may readily be recognized. 



The original specimen of this bird was obtained by Arce on the shores of the Gulf of 

 Nicoya in Western Costa Eica ^. Though we have seen other examples from that 

 country, the bird is by no means common. 



The species appears again on the isthmus of Teh uantepec, where Sumichrast obtained 

 specimens, but we have no record of it from any intermediate place.

Hab. Mexico, Chable in Yucatan (Gaumer^); Bkitish Hondueas {Blancaneaux) ; 

 Guatemala, Chisec, Choctum {0. S. & F. D. G^^). 



This species was described from specimens obtained by us in the forest-country north 

 of Cohan in Vera Paz ^, and we have since received skins both from British Honduras 

 and Yucatan. From the latter country Mr. Gaumer sent us, through M. Boucard, a 

 single example, together with skins of the closely allied E. verticalis. 



E. chloronota is a much smaller bird than its near ally E. striaticeps, rather duller 

 olivaceous on the back, and has a less clear grey chest. E. conirostris of Colombia and 

 Venezuela is another near ally, but is a much greyer bird, especially on the back. Its 

 relationship to E. verticalis is described below. 



The true E. chloronota has a very restricted range, and is probably confined to the 

 promontory of Yucatan and the forest country spreading southwards to the base of the 

 higher mountains of Vera Paz. Its range in altitude probably does not much exceed 

 1500 or 2000 feet.
