Synallaxis albigularis. — Synallaxis albiyula, Lafr. MS. 



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

 cibus alarum extus rujis : lateribus capitis et corpore subtus 

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

 bus et crisso brunnescenti-cinereis : rostri nigricantis yonyde 

 albicante : pedibus dare brunneis. 

 Long, tota 5',i, alas 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 to Temminck'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, pileo toto cum capitis lateribus niger- 

 rimis : subtus ochracescenti-albida, later aliter schistacea : gula 

 etpectore summo triangulariter nigro maculatis, maculis quoque 

 in ventris lateribus rotundis, obsolete schist aceis : tectricibus 

 subalaribus nigro-schistaceis : rostro et pedibus Jlavis. 

 Long, tota 7"0, alee 3*6, caudse 2*8, rostri a fronte *6, a rictu *85, 

 tarsi 1'4. 



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

 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 If. 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. R. Z. 1845, p. 341, 

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

 species known. 



THAMNOPHILUS iETHIOPS. 



cJ . Ater unicolor ; campterio et tectricibus subalaribus albo 



variegatis : rostro et pedibus nigerrimis. 

 ? . Castaneo-brunneus unicolor, alis intus obscurioribus } maculis 



quibusdam tectricum superiorum majorum apicalibus cum camp- 



terii margine et tectricibus subalaribus flavicanti-rufis : cauda 



nigra : rostro et pedibus nigris. 

 Long, tota 6*0, alse 2*8, caudae 2*5, rostri a rictu *85, tarsi *9. 

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

 but, whilst that has only a very insignificant white patch on the 

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