1863.] OF BIRDS FROM CENTRAL AMERICA. 187 



a bird as Meleagris ocellata exclusively exists, more may naturally 

 be looked for ; and I much regret my stay there was so limited. A 

 remarkably pleasant cruise down the west coast of Central America 

 in the ' Guatemala' also bore fruits, as Capt. Dow and I took every 

 opportunity to go ashore with our guns ; and Realejo and Piinta 

 Arenas have added two species to our present list. The rest are 

 from the high lands, districts I had left unexplored in my previous 

 journeys. I must thank Dr. Sclater for his kind assistance in deter- 

 mining the species. 



1. Thryothorus petenicus, sp. n. 



Svbtus brunneus, uropygio rubidiore ; superciliis et loris albis, 

 regione postocuJari brunnea ; lateribus capitis et colli albis 

 nigro minute striatis ; alis fusco-brunneis vix nigro transvit- 

 tatis; Cauda nigra, duabus externis recti'icibus albo irregulari- 

 ter punetatis, duabus mediis fusco-bminneis, his cum rectricibus 

 reliquis nigro fasciatis ; gula, pectore et ventre medio albis, 

 lateribus corjmris brunneis ; crisso albo fasciis nigris trans- 

 vittato. Rostro superiore corneo, inferiore albidiore ; pedibus 

 fuscis. 

 Long. tot. 5*1, alse 2'3, caudse 2 ; rost. a rictu 0'9 poll. Angl. 

 Hab. Peten. 



Similis T. modesto ex Guatemala et Costa Rica, sed rostro longiore 

 fasciisque caudee et crissi differt. 



This species, though like, is apparently quite distinct from T. 

 modestus, its nearest ally, the more strongly impressed markings of 

 the ear-coverts, the less rufous colour of the under parts, and the 

 well-defined bars of the crissum pointing to its distinction, I am 

 well aware that this latter feature would not alone justify specific 

 separation, some species of the genus Troglodytes presenting great 

 variety in this respect ; but considered in conjunction with other 

 characters, it must not be altogether rejected. 



2. Dendrceca niveiventris, sp. n. (PL XXIV. fig. 2.) 

 B. chrysoparia, Scl. P. Z. S. 1-862, p. 19, & Cat. p. 3.54. 



(J. Fronte, regione oculari et capitis lateribus Jlavis ; pileo

 uropygio fere omnino griseo ; pirimariis et secundariis obscure 

 fuscis, in pogonio externo griseo marginatis ; tectricibus ala- 

 rum minoribus nigj'is, mediis albo terminatis, tnajoribus nigris, 

 iti pogonio externo griseis, tnacula alba termiiiatis ; rectricibus 

 nigris, tribus utrinque lateralibus macula longa in j)ogo7iio in- 

 terno alba ; duabus externis in pogonio externo albis, deinde 

 nigris usque ad terminum, rectricibus interioribus griseo mar- 

 ginatis ; subtus gula et pecto?-e superiore pure nigris, deinde 

 omnino albis, lateribus vix nigro striatis ; tectricibus subalari-

5 similis mari, gula nigra absente'.
