corylinis. Long. tota 5-0, ale 2:4, caude 2:0, rostri a rictu 0°55, tarsi 0-9. (Deser. exempl. typ. ex 
Bebedero, Costa Rica. Mus, nostr.) 
Hab. Mexico, Hamelula, isthmus of Tehuantepec (Swmichrast *).—Cosra Rica, Nicoya 
(Arcé 1, v. Frantzius 2). 
In our original description of this species we compared it with E. chloronota, but we 
now think that H. 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 
Hi. superciliosa may readily be recognized. 
The original specimen of this bird was obtained by Arcé on the shores of the Gulf of 
Nicoya in Western Costa Rica!. Though we have seen other examples from that 
country, the bird is by no means common. 
The species appears again on the isthmus of Tehuantepec, where Sumichrast obtained 
specimens, but we have no record of it from any intermediate place.

This species was described from specimens obtained by us in the forest-country north 
of Coban 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 £. verticalis. 
£. 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. Z. conirostris of Colombia and 
Venezuela is another near ally, but is a much greyer bird, especially on the back. Its 
relationship to L. verticalis is described below. 
The true #. 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.
