Results of a Visit to South Guyana. 161 



greater part of the day ; on both sides, right and left, lies 

 interminable '' siriuba ^'-forest mixed with " anhinga/' — hot, 

 marshy, and inhabited by myriads of furiously biting 

 mosquitoes. Behind the village is dry forest for a kilometre 

 or two, where reasonable collecting should be possible if 

 mosquitoes were less numerous, and if the paths were not 

 sown with spring-guns armed for the destruction of entias 

 and pacas. The nearer part of this forest is somewhat 

 lighter, and has the much promising name of " bosque." 



Almost every morning and evening I visited the " bosque " 

 and the neighbouring parts of the high forest. I observed 

 regularly and collected there examples of Ibi/cter chimachima, 

 Asturina magnirostris , Chrysotis amazonica, Brotogerys vi- 

 rescens, Bucco tamatia, Galbula viridis, Ceophloeus lineatus, 

 Chrysoptilus punctigula, Celeus fiavus, Dendrohates sp. ind., 

 Saltator superciliaris^ Turdus albiventris, T. gymnophthalmus, 

 Thryophilus leucotis, Thamnophilus doliatus, Atlila thamno- 

 pliiloides, Formicivora grisea, and GlyphorJiynchus cuneatus. 

 I noticed also the delicate PoUoptila bnffoni, Lathria cineracea, 

 and a yellow-breasted Trogon, without getting good skins of 

 them. Among the favourite spoils of native bird-hunters I 

 often noted Rhamphastos errjthrorhynchus and OrtaUda 

 motmot. Every night, especially when there was moon- 

 light, the cry of Nyctidromus guyanensis was heard on the 

 roads around the village, and that of Nyctibius grandis in 

 the siriubdl. Once I heard of some specimens of Vanellus 

 cayennensis being in a plantation very near the village. The 

 only species entirely new for me alive was Turdus gymno- 

 phthalmus. 1 had never before seen the " Bare-eyed Thrush,'^ 

 and I doubt whether it has been observed in any region 

 southward of Trinidad and Cayenne. The naked space 

 around the eye is yellow in life; it is impossible to confound 

 this well-marked Thrush with any other neotropical species. 



On the orange-trees in the village I saw and heard every 

 moment, even during the hottest hours of the day, a number 

 of common birds also met under similar circumstances in 

 Para, such as Tityra cayana, Todirostrum maculatum, Myio- 

 dynastes audax, Empidonomus varius, Myoputis semifusca,
