prints in question. Thus the papilliform granulation of the skin of 

 tlie Cheirotherium is in favour of the zoologists who have regarded 

 it as a Mammal. Now, this last conclusion is of importance, inas- 

 much as it leads to the admission that Mammalia existed on the 

 surface of the globe at the time of deposit of the most ancient strata 

 of the Triassic period." — Comptes Rendus^ Oct. 26, 1857, p. 646. 



On two new species of Birds from Bogota. 

 By P. L. ScLATER, Esq. 



Anabates striaticollis. 



Olivascenti-brunneus, capite virescentiore et hujus plumis tenuis- 

 sime nigro marginatis : alis nigricantibus, extus brunneOy intus 

 autem cinnamomeo marginatis : subtus clarior et cinnamomeo 

 tinctus ; gutture et pectore antico pallidioribus et scapis plu- 

 marum cum harum 'parte mediali dare fiavicanti-albidis, strias 

 obsoletas formantibus : cauda unicolore rufa : rostro flavido, 

 culmine brunnescente, pedibus nigricantibus. 



Long, tota 6 0, alee 3*3, caudae 2*6. 



I have lately obtained a Bogota skin of this Anabates. Another 

 specimen, which was previously in my collection and has been sub- 

 mitted to M. de Lafresnaye's examination, is marked in his hand- 

 writing " Anabates striaticollis, Lafr." I have therefore used that 

 name, though as yet, I believe, unpublished. These two examples 

 merely differ in their slightly inferior size from a third specimen 

 marked " Anabates olivaceiventer " by M. de Lafresnaye some years 

 since. I do not know whether he considers the two species indi- 

 cated by these MS. names as distinct. For myself I doubt the fact. 

 The cervical striae, whence the name is derived, are not very well 

 marked in my Bogota specimens. 



SCLERURUS BRUNNEUS. 



S. supra brunneus cinnamomeo tinctus, subtus paulo pallidior ; 

 gutture albo mixto : alarum et caudce pennis intus nigricanti- 

 bus, illarum marginibus externis dorso concoloribus : rostro 

 nigro, basi flavicante : pedibus nigris. 



Long, tota 6*0, alse 3*4, caudae 2*1. 



I have lately obtained a single Bogota skin of a bird of this genus, 

 to which (as I cannot associate it with any of the already-described 

 species) I have given a new name. From S. caudacutus of Brazil 

 and S. mexicanus (P. Z. S. 1856, p. 290) of Mexico and Guatimala, 

 it differs in the want of the bright rufous colouring in the rump and 

 fore neck. In this respect it would seem to resemble Hartlaub's 

 S. guatimalensis (Rev. Zool. 1844, p. 370), but that bird is said to 

 be of the size of *S. caudacutus, to which the present species is con- 

 siderably inferior in dimensions. — Proc. Zool. Soc. Jan. 27, 1857.
