CINCLOCERTHIA MACRORHYNCHA. 



(LONG-BILLED TEEMBLEE). 



Cinclocertliia macrorhynclia 



Sclater, P.Z.S. 1866, p. 320. 



Supra obscure cinerea, fere unicolor, capite prsecipue ad latera nigricantiore : subtus lactescenti-alba, pectore et 

 crisso cum lateribus et subalaribus fusco-cinerascentibus : rostro paulum incurvo, nigro ; pedibus corylinis : long, 

 tota 10'5, alse 41, caudse 3'3, rostri a rictu 2*0, tarsi 1*15. 



Hab. in insula S. Lucia, Antillarum {Bonnecourt). 



The only example of this species we have yet met with is the typical specimen described 

 by Mr. Sclater as above referred to, from which also our figure has been taken. The example 

 in question belongs to the Museum d'Histoire Naturelle of the Jardin des Plantes, and we have 

 to express our great obligations to the authorities of that establishment for allowing us the use 

 of it for this work. 



M. Bonnecourt, the collector of this unique specimen, obtained it in Sta. Lucia in the year 

 1850. It is labelled " Le Grive Trembleuse" which is, as we have already remarked, the same 

 name that C. ruficauda bears in Guadeloupe. The sex is noted to be female, but the male is, 

 without doubt, scarcely different. 



In a small series of drawings of the birds of Sta. Lucia by Lieut. Tyler, in the Zoological 

 Society's Library, is a figure, evidently intended for this bird, marked " The Trembler." 



The present species is at once distinguishable from its two allies by its long bill, but in 

 other points of structure does not materially differ from them. The first (spurious) primary is as 

 large as in the other two species, measuring 1*5 inch from its insertion, and being rather more 

 than half the length of the second primary. The third is slightly shorter than the fourth, fifth, 

 and sixth, which are equal and longest. The present specimen of (7. macrorhyncha has the 

 tarsi covered anteriorly with a continuous horny sheath, the divisions of the tarsal scutes having 

 become almost obsolete. In specimens of C. ruficauda and C. gutturalis, these divisions are 

 distinctly indicated and the scutes are five in number, which is probably the normal form of 

 the genus.
