similar outward appearance, but readily distinguishable upon close 

 examination, are true Wrens in structure. The same observation 

 may be made of Lafresnaye's Scytalopus griseicollis from Bogota. 

 Cabanis gives Guiana and Mexico as localities for his C. leucostictus ; 

 if the birds from these two localities are not identical (as I think is 

 likely to be the case), the S. American bird may retain Cabanis's 

 name, and the Mexican species be called Cyphorinus prostheleucus. 

 The specimens in the present collection differ from the Mexican bird 

 in their rather larger size, longer bill, and the deeper chestnut of the 

 back and upper wing- coverts, which latter are not nearly so much 

 spotted with white. 



40. Thryothorus coraya (6m.). 



Rather darker head, but hardly distinct from the Cayenne bird. 



41. Myiodioctes canadensis (Linn.). 



42. RhIMAMPHUS BLACKBURNIiE, JUV. 



43. Rhimamphus ceruleus (Linn.), juv. 



44. Turdtjs minimus, Lafr. 



45. Turdus phjeopygos, Cab. in Schomb. Guian. hi. p. 666. 

 Back slightly darker, but not apparently otherwise different. 



46. Malacocichla maculata, sp. nov. 



Catharns maculatus, J. Verreaux, MS. 



Siipra nigricanti-schistacea, pileo toto cum capitis lateribus niger- 

 rimis : subtus ochracescenti-albida, lateraliter schistacea : gula 

 et pectore snmmo triangulariter nigro maculatis, maculis quoque 

 in ventris lateribus rotundis, obsolete schistaceis : tectricibus 

 subalaribus nigro-schistaceis : rostro et pedibus jtavis. 

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

 tarsi l - 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 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. R. Z. 1845, p. 341, 

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

 species known.
