5. Descriptions of Six New Species of American Oscines. 

 By P. L. Sclater, M.A., Ph.D., Secretary to the Society. 



1. Tl'RDUS SUBCINEREUS, Sp. 110V. 



Supra obscure cinereus, alls caudaque fuscis, extus cinereo tnar- 

 ginatis : subtus albo- cinereus, gutturis et pectoris plumarum 

 rachidibus fusco-cinereis, crisso fulvescente lavato ; subalari- 

 bus cinerascenti-albis fulvo vix tinctis : rostro corneo ; mandi- 

 bula inferiore pallida ; pedibus obscure fuscis : long, tota 8'2 

 poll. Angl., alceA'd, caudce 3*8, rostri a rictu 8"5, tarsi 1 " 15. 

 Hub. (ut dicitur) in rep. Chilians. 

 Mus. P. L. S. 



Obs. Affinis T. chiguanco, Lafr. et D'Orb., et fere ejusdem formae, 

 sed statura valde minore, pectore obsolete striato et subalaribus non 

 cinnamomeis distiuguendus. 



I have a single skin of this Thrush in my collection, purchased of 

 M. Verreaux of Paris, and marked " Chili." I have not met with 

 other specimens. The species is not very closely allied to any other 

 that I am acquainted with, but seems to go best in the series allied 

 to Tardus chiguanco. Tbe first (or spurious) primary is rather 

 large, measuring 1*5 inch from the insertion. The fourth and fifth 

 primaries are equal and longest, slightly exceeding the third and 

 sixth. The bill is rather short and more compressed than in most 

 species of the genus. 



2. ClNCLOCERTHIA MACRORHYNCHA, Sp. nOV. 



Supra obscure cinerea, fere unicolor, capite prcecipue ad latera 

 nigricantiore : subtus lactescenti-alba, pectore et crisso cum 

 lateribus et subalaribus fusco-cinerascentihus : rostro paulum 

 incurvo, nigro ; pedibus corylinis : long, tota 105, alee 4"1, 

 caudte 3*3, rostri a rictu (lin. dir.~) 2*0, tarsi 1*15. 



Hab. in ins. S. Lucia, Antillensium (Bonnecourt). 



Mus. Parisiensi. 



Obs. Species a C. ruficauda corpore supra omnino cinereo, a C. 

 gutturali colore corporis inferi dilutiore, ab utraque rostro elongato 

 incurvo distinguenda. 



This bird forms a very distinct third species of the Antillean 

 genus Cmclocerthia, of which two species are given in mv " Synopsis 

 of the Turdida" (P. Z. S. 1859, p. 338). As we should have ex- 

 pected, it comes from a different island from those which the other 

 two species inhabit. While C. ruficauda is found in Nevis and 

 Guadeloupe, and C. gutturalis in Martinique only, as far as we know, 

 the present species is from the island of Santa Lucia. I am indebted 

 to my friend M. Jules Verreaux, Aide-Naturaliste to the Museum of 

 Natural History at the Jardin des Plantes, for the opportunity of 

 describing this species — the only specimen I have yet met of it oc- 

 curring in that collection, to which it was transmitted by M. Bon- 

 necourt in 1850.
