Synallaxis ALBIGTJL.AR1S. — Synallaxis albigula, Lafr. MS. 

 Supra murino-brunnea ; cauda concolore ; jjileo postico et tectri- 

 cibus alarum extits rujis : lateribus capitis et corpore subtiis 

 cinereis : loris albidis : gula et ventre medio pure albis, lateri- 

 bus et crisso brunnescenti-cinereis : rostri nigricantis gonyde 

 albicante : pedibus dare brunneis. 

 Long, tota 5*o, alse 2*3. 



A short-tailed species of Synallaxis, as I should judge from the 

 only specimen under observation, in which, however, the medial rec- 

 trices are absent. It is very nearly allied toTemminck's S. albescens, 

 but differs sufficiently in its white throat and belly, as far as I can 

 judge from the unique specimen. 



Malacocichla maculata. 



Catharus maculatus, J. Verreaux, MS. 



Supra nigricanti-schistacea, j)ileo toto cum capitis lateribus niger- 

 rimis : subtus ochracescenti- albidu, lateruliter schistacea : gula 

 et pectore sunimo triangulariter uigro inaculatis, maculis ipioque 

 in ventris lateribus rotundis, obsolete schistaceis : tectricibus 

 subalaribus nigro-schistaceis : rostro et pedibus jlavis. 



Long, tota 70, alee 3'6, caudse 2*8, rostri a fronte 'G, a rictu "S;), 

 tarsi 1'4. 



This interesting bird is a close ally of Gould's Malacocichla Dryas 

 from Guatemala, and I have therefore placed it in the same genus. 

 It may be distinguished from that species by the dark slaty colour 

 of the back, which in M. Dryas is greenish olive. Whether these 

 birds will be ultimately separable from the genus Catharus is, I 

 think, questionable ; and M. Jules Verreaux is therefore quite as 

 likely to be correct in his appellation of this species as I am in mine. 

 Besides M. Dryas from Guatemala (P. Z. S. 1854, p. 285, pi. 75), 

 Prince Bonaparte has described a Mexican species — M. mexicana 

 (Compt. Rend. Aug. 2, 1856). The Prince also informed me (after 

 a visit to M. de Lafresnaye's collection, which he made shortly before 

 his decease) that Myioturdus fuscater, Lafr. 11. Z. 1845, p. 341, 

 belongs to this same genus — so that this is probably the fourth 

 species known. 



ThAMNOPHILUS iETHIOPS. 



(5 . Ater unicolor ; campterio et tectricibus subalaribus albo 



variegatis : rostro et piedibus nigerrimis. 

 $ . Castaneo-brunneus unicolor, alis intus obscurioribus, maculis 

 quibusdam tectricum superiorum majorum apicalibus cum camp- 

 tern margine et tectricibus subalaribus Jtavicanti-rujis : cauda 

 nigra : rostro et pedibus nigris. 

 Long, tota GO, ahxi 2*8, caudse 2*5, rostri a rictu *85, tarsi "9. 

 This species is in colour like T. immaculatus, of a uniform black ; 

 but, whilst that Ik.s only a very insignificant white patch on the 

 bend of the wiiig, the T. ccthiops has the under wing-coverts as well
