Gen., i. p. 298. 



" Nigro et late cristatus ; crista a basi tota nigra ; supra et 

 subtus nigro alboque striatus, sed striis albis dorsalibus fere 

 squamoeformibus, undulatis, striisque nigris pectoralibus dis- 

 tantibus ; abdomine medio albo ; cauda punctis minutis striata. 

 Long, tota 16 J cent. Hab. in Nova Grenada, Bogota." 



I can only give the Baron de Lafresnaye's description of this 

 species, which I have not yet seen. He adds, that it is closely 

 allied to Th. albicans and multistriatus, as well as doliatus, 

 but is distinguished by its beak being shorter and more ele- 

 vated at the base, by its dorsal bands being more undulated, 

 and its tail being nearly black, traversed only by lines of very 

 small white points.

" T. cristatus, crista nigra ; supra totus ater maculis minimis 

 vel potius punctis albis quasi aspersus ; remigibus atris, vexillo 

 interno tantum maculis triangularibus latioribus albis mar- 

 ginato ; rectricibus totis nigris acutissime limbo externo albo 

 punctatis ; subtus totus nigro alboque fasciatus, colli antici 

 pectorisque fasciis nigris paulo latioribus quasi squamseformi- 

 bus ; rostro nigro, tomiis apiceque albescentibus. Long, tota 

 14 cent. Habitat Anolaima in Nova Grenada." (Lafr.)

$ supra niger, confertim albo trans-fasciatus, subtus albo 

 nigroque alterne vittatus, gutture magis striato. 



$ supra rufo-castanea ; subtus et in colli lateribus albo 

 nigroque crcbro trans-fasciata ; cauda rufa. Long, tota 4-8,

My characters for this species are taken from specimens 

 which agree in all essential points with M. de Lafresnaye's 

 descriptions. The male has no crest, and the head and whole
