406 NOVITATES ZOOLOQIOAE XXIX. 1922. 



? t 1155. Chrysiironia oenone intermedia Hart. = 1 Chrysuronia oenone 



josephinae. 

 Chrysuronia oenone intermedia Hartert, Nov. Zool. 1898, p. 519 (" Upper Amazons "). 



Type : c? ad., " Peru," apparently from Pebas, Upper Amazons. Pmr- 

 chased from H. Whitely. 



(On the Upper Amazons in Peru specimens are found with a blue chin, while 

 C. oenone oenone has the whole throat blue, C. oenone josephinae no blue on chin 

 and throat. Simon is, perhaps rightly, of opinion that the difference of intermedia 

 is individual rather than limited geographically, but this question requires 

 further investigation.) 



1156. Chlorostilbon caribaeus nanus Berl. & Hart. = Chlorostilbon caribaeus nanus 



Chlorostilbon caribaeus nanus Berlepsch & Hartert, Nov. Zool. 1902, p. 86 (" In regione media fluminis 

 Orinoco, Caicara; Altagracia, etc."). 



Type: c? ad., Caicara, 19. ii. 1898. Geo. K. and Stella M. Cherrie leg. 

 No. 10157. 



(I fail to understand the treatment of this group by Simon in 1921. He 

 places C. c. nanus as a synonym of C. daphne suhfurcata Berl. and redescribes, 

 on p. 63, the Orinoco subspecies as a form of caribaeus under the name of Prasitis 

 caribaea orinocensis, from Ciudad Bohvar and S. Fernando de Apure. He thus 

 recognises two species occurring together in the basin of the Orinoco, P. caribaea 

 (orinocensis) and P. daphne (suhfurcata). If this was as Simon beUeves, Berlepsch 

 would have redescribed his subfurcatus as nanus ; that is, however, not the 

 case ; Berlepsch had his subfurcatus and our nanus before him and I had topo- 

 typical specimens of the former for comparison, and the two are quite distinct, 

 subfurcatus having a much less emarginated, almost square tail and a more blue 

 throat, than nanus. I would not without hesitation place subfurcatus and nanus 

 as subspecies of one species, and probably would unite five or six forms as sub- 

 species of one species, the oldest name of which I cannot at present decide. If 

 Simon is right, that two species inhabit the Orinoco valley, then one of them is 

 not known to me, in any case the bird which Berlepsch and I described as a sub- 

 species of caribaeus is the same bird which Simon redescribed as orinocensis in 

 1921. Simon on p. 63 united his and Dalmas' lessoni with caribaea ; on p. 291, 

 however, he says that he was in error, and that it must be separated. I have 

 purposely united the two, i.e. the form from Curagao, Aruba and Bonaire (true 

 caribaeus), and the one from the Venezuelan littoral, and the islands of Margarita 

 and Trinidad (lessoni), and if they should after all be separable they are certainly 

 " tres Mgerement " different, as evidenced by the wavering of an authority like 

 Simon himself.) 



f 1157. Agyitria tenebrosa Hart. = Thalurania lerchi. 



Agyrtria tenebrosa Hartert,' Bull. B.O. Club, x. p. 15 (1899 — from a specimen of the usual Bogot4 

 preparation). 



Type : A Bogota trade skin. 



(While there is no doubt that I redescribed — and in a wrong genus too — 

 the species known as Thalurania or Timolia lerchi Mulsant & Verreaux, Ann. 

 8oc. Lyon, 1872, p. 108, also from a Bogota skin, I cannot admit that it is separable 

 from the genus Thalurania. Both in Brabourne & Chubb's List of the B. of 8.
