NOVITATES ZOOLOGICAE XXIV. 1017. 495 



The Venezuelan birds being different from setopTiagoides, they must be called 

 M. leucophrys nigriceps, though we .should not have attempted to name such a 

 closely allied form from a single unsexed specimen, as such work can only be 

 suggestive and not definite. Nor is the name nigriceps a suitable one, as the 

 crown is by no means actually black, though a shade darker than the back. 



Two specimens from Mt. Roraima, British Guiana, collected by Whitely, 

 agree in their small size with M . I. nigriceps, but are as dark on the upperside 

 as M . I. seiophagoides. The Guiana specimens in the British Museum agree with 

 those in Tring and it wUl probably become necessary to separate them. 

 The material in the Tring Museum is as follows : 



M. I. leucophrys : Tucuman and S. Peru, 8 o?- 

 M. I. nigriceps : Merida, Caracas, Cumana, 12 ^$. 

 M. I. subsp. nov. 1 : Guiana, 2 <??. 

 M. I. setophagoides : Bogota, 9 



We have no specimen of the typical leucophrys from Bolivia. 



On the subspecies of Cymbilanius liueatus. 

 There are at least four forms of this species, as follows : 

 1. Cymbilanius lineatus lineatus (Leach). 



Lanius lincatns Leach, Zool. Misc. i. p. 20. pi. C (1814 — Berbice, Guiana). 



The males are darker than those of all the other races, the white cross-bars 

 narrower, those on the underside less wide than the black bars. The females 

 have the tail black-brown, almost black, with rather narrow pale rust-brown 

 bars ; J wing 76-80, ? 76-79 mm. 



4 <J(J, 4 ?? British Guiana, Surinam and Cayenne. 



2. Cymbilanius lineatus intermedins, subsp. nov. 



cj. The white cross-bars on the upperside are slightly, those on the 

 underside much wider, being as broad as or broader than the black ones. 

 In the $ the rusty cross-bars are slightly wider on the upperside, the bars on 

 the outer webs of the quills and wing-coverts are wider and more rufeseent, 

 the tail has wider and more rufeseent cross-bars, and the ground-colour is more 

 brownish, not so blackish. Underside lighter, the barring more or less incomplete 

 in the middle. Wing S 75-78, ? 75-77 mm. 



Rio Madeira, Brazil (terra typica), Santarem, Teffe on the Rio Solimoes, 

 Yquitos in Peru, Chucurras in the province of Huanuco, Peru. 



Type : ? Humaytha, Rio Madeira, .31. vii. 1906. W. Hoffmanns coll. 



We have before us 8 males and 7 females from Humaytha, Calama, Borba, 

 Allianca, Uricurutaba near Santarem (Lower Amazons), Teffe, all collected by 

 the late W. Hoffmanns, 1 S from Chucurras, and 1 ? from Yquitos in Peru, 

 collected by H. Whitely. We have also 5 SS and 4 $? from the Caura River, 

 collected by Andre and Klages, which we cannot separate from these birds. 



3. Cymbilanius hneatus, subsp. nov. ? 

 Males from North-west Ecuador have the white bars on the underside even 

 wider than in C. I. intermedins, and in C. I. fasciatus from Central America, but 

 are certainly nearer to the former than to the latter. C. I. fasciatus is in both
