be only a subordinate form, connecting this with Furnarius. * 1 

 form this opinion, because, by this disposition of the groups in 

 the two circles, the contents of each will mutually represent 

 each other, in the following manner: — 



Anabatinje. CeRTHIANjE. 



Dendroma. Oxynrvs. 



Synallaxis. Certhia. 



Geobates. Furnarius. 



Zenops. Zenophasia, 



Anahates. Dendrocolaptes. 



Zenophasia platyryncha. 



Brown, inclining to chestnut on the hack, and to ful- 

 vous beneath : chin, throat, breast, and sides of the 

 head, varied wdth whitish stripes : body immaculate : 

 inner base of the quills with a fulvous white band : 

 inner wing covers white : tail rufous. 



Inhabits Brazil. Mus. Nost. 



Size of Zenops affinis ; but the tail is considerably longer. 

 Total length 5\ inches ; bill, gape ^ ; front A ; Avings 21 ; tail, 

 beyond, 1^ ; base 2^^ ; tarsus ^. The ground colours are pre- 

 cisely the same as the rest of the Dendrocolapti ; but there are 

 no pale stripes on the upper plumage, and they disappear a 

 little beyond the breast. 



210. Zenops affinis. 



Chin, part of the throat, and stripe beneath the ears, 

 pure white : tail rufous ; the third pair of lateral fea- 

 thers black on their inner webs : bill with the culmen 

 very straight, and the commissure recurved. 



Inhabits Brazil. Mus. Nost. Zenops genibarbis, 

 Zool. lU. i. pi. 100. nee. Temm. PI. Col. 150. f. 1. 



M. Temminck observes of the tail of his geniharhis, " le 

 roux vif est place au bout de chaque penne, le deux demilieu 

 exceptees, qui sont d'un noir profond ; le roux occupe plus 

 d'espace sur les pennes laterales qui sur celles placees vers le 

 centre." In this, on the contrary, the whole of the feathers 



* Another view, indeed, may be taken of this question ; namely, that the 

 birds I have placed under the subgenus Dendrocolaptes, are but aberrant 

 species of my Ziphorynchus : if this be correct, which I at present doubt, 

 then Z. procia-vis will stand as the type of Dendrocolaptes, and my sub- 

 genus Dendrocolaptes must be abolished : Zenophasia would then come in 

 as one of the five subgenera, still representing Zenops as a subgenus of 

 Dendrocolaptes.
