The following notes relate to the new and more remark- 

 able species of Mr. Whitely^s last collection : — 



"'"^—MiCRocERCULUs usTULATus, sp. n. (Plate IX. fig. 2.) 

 Cinnamomeo-brunneus fere unicolor^ gutture toto dilutiore ; 

 alis extus et cauda lineis obsoletis fuscis transfascia- 

 tis ; rostro nigricante^ mandibulse basi albicante : long, 

 tota 4*4, alse 2*35, caudsB IS^ rostri a rictu 0'35, tarsi 

 0-95.

Mr. Whitely obtained three specimens of this distinct 

 species, which has no near allies. It is distinguished by its 

 rich cinnamon-brown plumage, which is almost destitute of 

 markings, faint dark cross bars on the wing and tail being 

 all that can be traced. 



"^-Ctstothorus alticola, sp. n. 

 Supra brunneus, pileo immaculato, interscapulio nigricante 

 plumis singulis medialiter linea albida notatis, alis et 

 Cauda frequenter sed irregulariter nigro transfasciatis ; 

 subtus albidus, pectoris lateribus, hypochondriis et crisso 

 brimneis ; rostro et pedibus corylinis, illius mandibula 

 albicante: long, tota 4'1, alse 1"75, caudse \7, rostri a 

 rictu 0*55, tarsi 0"65. 

 Hab. Roraima, Guiana Brit. {H. Whitely). 

 Mus. nostr. 



Obs. B. brunneicipiti similis, sed statura minore, colore 

 minus rufescente, fasciis alarum frequentioribus et fasciis 

 caudse irregulariter disjunctis distinguendus. 



Though belonging to the same section of the genus Cisto- 

 thorus as C. brunneiceps (Salv. Ibis, 1881, p. 129, t. 3. f. 1), 

 this species presents several differences, which render it easily 

 recognizable on comparison. Like C. brunneiceps, the head is 

 uniform brown, without stripes of any kind ; but the colour 

 is rather duller in tint ; beneath C. alticola is whiter, and the 

 flanks are also less rufous in colour. The differences of the 

 markings of the wings and tail alluded to above are strong 

 characteristics. 



Mr. Whitely has sent us several specimens of this species.
