24 HIRUNDINID^E. 



24. CYCLORHIS ALTIROSTRIS, Salvin. 

 (DEEP-BILLED GREENLET-SHRIKE.) 



[PLATE III. FIG. 2.] 



Cyclorhis altirostris, Sdlv. Ibis, 1880, p. 352 ; Gadow, Cat. B. vili. p. 319, 

 Cyclorhis viridis, Barrows, Bull. Ntttt, Orn. Cl. viii. p. 88 (Concepcion, 

 Entrerios) ; Berl. et Jher. Zeitschr. yes. Orn. 1885, p. 116. 



Desertion. Above olive-green ; head more or less rufescent ; front and 

 Buperciliaries chestnut-red ; sides of head grey ; beneath pale ochraceous j 

 breast and sides yellow ; throat greyish ; bill short and thick, pale reddish, with 

 a black blotch at the base of the lower mandible ; feet reddish : total length 

 6'5 inches, wing 3-3, tail 3*0. Female similar. 



Hab. Paraguay and Northern Argentina. 



This species was met with by Durnford near Salta in June 1878. 

 He describes the iris as " light rufous ; upper mandible dark slate, 

 under mandible, legs, and feet pale slate " 



Mr. Salvin founded his C. altirostris upon Durnford's specimens, but 

 Graf v. Berlepsch is of opinion that this species is the "Habia verde" 

 of Azara, and should consequently bear the name "viridis" of Vieillot. 

 This is perhaps correct, but at the same time it would only make fresh 

 confusion to transfer to this species the name hitherto usually applied 

 to the preceding bird. We prefer, consequently, to let it stand under 

 Mr. Salvin' s name " altirostris." 



Fam. VIII. HIRUNDINHXaE, OR SWALLOWS. 



The cosmopolitan family of Swallows, of which about eighty species 

 are known, is well developed in the New World, where some thirty 

 representatives occur in various parts. In Argentina the occurrence of 

 eight Swallows has been recorded. Three of them belong to the group 

 of Purple Martins (Progne), which is restricted to the New World, and 

 of the remainder four are members of genera entirely restricted to the 

 Neotropical Region. The genus Petrochelidon, of which one species is 

 met with in La Plata, has alone representatives in the Eastern Hemi- 

 sphere.

(PURPLE MARTIN.)

 1872, p. 605 ; Scl. et Salv. Nomencl. p. 14 ; Durnford, Ibis, 1877, p. 32 (Chupat), 



* [1 here follow Mr. Sharpe in considering the Purple Martin of Argentina and 

 Patagonia separable from the closely allied northern species of North America. But 

 I am altogether sceptical about its occurrence in Chili, which Dr. Philippi expressly 

 daries (P. Z. S. 1868 p. 534) and for which I know of no good authority. P. L. S.]
