tion, does not appear to us to belong to either of the genera of swallows here- 

 tofore established. It has somewhat the bill of Collocalia, with the wings and 

 tail of Petrochelidoii, and very small and weak tarsi and feet. It may readily 

 be distinguished by its pure white thighs, and is probably South American, 

 though we have no reliable indication of locality. An obscurely marked speci- 

 men in the collection, but which we regard as possibly the young of this species, 

 is labelled as coming from Brazil. 



4. Cecropis badius, nobis. 



Form. About the size of C. striolata (Temm.) and rather larger than Ilirundo 

 rufa or H. rustica* Not so large as C. senegalensis^ but strictly congeneric 

 with it and other species of this group as given by Bonap. in Cons. Av. p. 339. 



Bill rather strong, wings moderate with the first quill slightly longest, some 

 of the secondaries irregularly indented at their tips, tertiaries emarginate. Tail 

 deeply forked, two outer feathers narrow and acuminated to their tips, tarsi and 

 feet strong. 



Dimensions. Total length (of skin) from lip of bill to end of tail about 7 in., 

 wing 5|, tail 4 inches. 



Colors. Rump and entire under parts from the base of the lower mandible to 

 the tail coverts, deep chesnut brown, on the under parts of the body, every 

 feather having a minute central line of black, not observable on the rump. 

 Under tail coverts widely tipped with black. No white spots in the tail nor on 

 any other parts of the plumage. 



Neck behind with a collar, not well defined, of same chesnut brown as the 

 under parts of the body. Head above, back, wing coverts, upper tail coverts, 

 wings and tail black, with a bluish violet lustre inclining to green on the wings. 

 Inferior wing coverts chesnut. 



Hah. Malacca ? 



Obs. Two specimens of this fine swallow^ were selected by the writer from a 

 large collection of Indian birds which had just been received by the eminent 

 naturalist and taxidermist, Mr. John G. Bell, of New York. He was informed 

 that the collection had been imported from Malacca. 



This species agrees very nearly in size with the Javanese species of this diffi- 

 cult genus, C. striolata (Temm. and Schl.) but can readily be distinguished from 

 that or from any other species by the deep chesnut color of the under parts of 

 the body, which is almost immaculate, and much darker than in any other spe- 

 cies known to me, or which I have found described. 



II. PSITTACID.^. 



1. ChRYSOTIS VIRIDIGENALIS, nobis. 



Form. Large, about the size of C. aiitnmnalis (Linn.) Bill strong, culmen 

 curved from the base and slightly grooved. Wing with the second, third and 

 fourth quills longest and nearly equal, quills broad, tail of twelve feathers, mo- 

 derate, rather broad, tarsi short, robust. Small space around the eye, bare. 



Dimensions. Total length (of skin) from tip of bill to end of tail about 12 

 inches, wing 8, tail 42 inches. 



Color. Top of the head from the base of the bill, fine crimson, varying in 

 extent in different specimens, other plumage of the head above green at the 

 base of the feathers, many of them having subterminal transverse bands of 

 bluish cinereous, and all narrowly tipped with black. Cheeks fine pale green 

 (with no yellow or red.) 



Entire plumage above and below green, darker on the back and tinged with 

 yellow on the under parts, every feather of the back, rump, neck, breast and 

 abdomen narrowly tipped or edged with black. First primary black, others 

 green for the greater part of their length, but bluish black at their tips. A 

 large spot of fine crimson occupying about the middle third of the first five 

 or six secondaries, which are tipped with fine blue. Tail above and below dark 

 green at the base, terminal portion greenish yellow, central feathers darkest, 

 some of the outer feathers edged with reddish chesnut at their bases. Under 

 tail coverts yellowish green, shafts of the feathers black.
