55. Dysithamnus scHisTACEUs(D'Orb.). — Thamnophilus schis- 

 tacens, D'Orb. Voy. p. 170. pi. 5. fig. 1. 



c? . Obscure cinereus, subtus vix dilutior, macula parva sub dorsi 



medii pennis et rectricum margine apicali angusta albis : rostro 



et pedibus nigris. 

 2 . Obscure brunnea, subtus fiavicanti-rufescens, gula albicante ; 



alis caudaque nigricanti-fuscis, rectricum margine apicali ru- 



fescenti-alba. 

 Long, tota 5 # 5, alee 2*8, caudae 1*9, tarsi *75. 

 Obs. — Affinis D. plumbeo ex Brasilia, sed alis concoloribus neque 

 albo marginatis. 



I refer this bird with some doubt to D'Orbigny's species. 



56. Dysithamnus leucostictus, sp. nov. 



Supra umbrino-brunneus, pileo rufescentiore, pennis omnibus in- 

 terne cinereis : subtus cinereus, capitis lateribus cum gula et 

 pectore guttis elongatis albis, pennas medias occupantibus, ma- 

 cula tis : ventri lateribus et crisso olivaceo tinctis : cauda ob- 

 scure nigra, extus brunneo marginata : rostro et pedibus nigris. 

 Long, tota 5*2, alae 2 - 75, caudae 2'0, tarsi I "85. 

 This species is noticeable on account of the clear white elongated 

 shaft-spots on the throat and breast, which distinguish it from other 

 birds of the group. In two younger specimens in MM. Verreaux's 

 collection these spots are hardly yet apparent, and the rich brown 

 edging of the upper plumage is only partly assumed, leaving these 

 parts of a brownish cinereous.

58. Pyriglena serva, sp. nov. 



3 . Nigra, subtus magis ardesiaca : macula magna interscapula- 

 rium interna et tectricum alarium superiorum marginibus apica- 

 libus cum campterio albis ; rostro et pedibus nigris. 

 5 . Olivascenti-cinerea, macula interscapularium interna alba : 

 subtus saturate ferruginea ; alis caudaque fuscis, tectricum 

 alarium superiorum marginibus et tectricibus subalaribus rufes- 

 centibus ; rostro superiore nigro, inferiore Jlavido : pedibus 

 fuscis. 

 Long, tota 5*3, alse 2*5, caudae 2*3, rostri a rictu - 8, tarsi 0*9. 

 Distinguished from Pyriglena domicella and P. atra by its smaller 

 size. Sir William Jardine recently lent me some specimens of For- 

 micariidcB from Quixos, among which were examples of both sexes of 

 this same species. I do not know Lanius funebris, Licht. (Doubl. 

 p. 47), from Cayenne, but as far as 1 can judge from his short cha- 

 racters, it can hardly be identical with the present bird.
