6213. C. ossifi-agus, Wils. (Am. Orn. v. p. 27, 1812), is smaller in size than C. americanus, to which it 

 appoaches nearest ; the bill is broader at the base and tapers more ; and the gloss on the belly is green 

 instead of violet, and the back is also glossed with green. Wing 10'5 inches, tail 6 - 5, culmen 1'55, 

 tarsus l - 65, being shorter than the middle toe and claw (fide Baird). It inhabits the Atlantic coast 

 from New Jersey to Florida. 



6214. C. caurinus, Baird (B. of N. Am. p. 569, 1858), is smaller than C. americanus, but has the plumage 

 glossed as in that species, though deeper. Culmen P95, wing 10 - 5, tail 6 - 4, tarsus 17. It inhabits 

 the north-western coast of North America. 



6215. C.jamaicensis, Gm. (Syst. Nat. i. p. 367). I do not possess a specimen of this bird, which Professor 

 Baird describes as follows : — " Nostrils just covered by the short but dense tuft of nasal bristles ; 

 entirely dark sooty plumbeous inclining to black ; on the head, wings, and tail there is a very faint 

 violaceous gloss. Wing 95 inches, tail 6"5, culmen 2 , 0, depth of bill \'7, tarsus 2'05." It inhabits 

 Jamaica. 



6216. C. solitarius, P. v. Wiirt. (Naum. ii. 2. p. 55) . I do not possess this species, which Schlegel describes 

 as resembling C. americanus but much less. He gives the measurements as — wing 9| inches, tail 5|, 

 culmen 1|, height of beak §, tarsus 1|-. It inhabits Haiti. 



6217. C. nasicus, Temm. (PI. Col. 413) . Professor Baird describes this species as " entirely violaceous black ; 

 the feathers smoke-grey beneath the surface ; nostrils scarcely concealed by the short nasal bristles. 

 Wing irO inches, tail 7'75, culmen 2'45, depth of bill 08, tarsus 1-95." It inhabits Cuba. 



6218. C. minutus, Gundl. (J. f. O. 1856, p. 97). I have never seen a specimen of this bird; but Professor 

 Baird says that it appears to be nearly related to C. ossifragus. It inhabits Cuba. 



6219. C. mexicanus, Gm. (Syst. Nat. i. p. 375). This Crow is very distinct from all others of this group, 

 being not only very small, but the plumage is as richly glossed with purple, violet, and bronze, and as 

 highly lustrous as that of a Grackle. According to Colonel Grayson (B. of W. and N.W. Mexico, 

 Boston Soc. Nat. Hist. ii. p. 283) it appears to be confined to the north-western parts of Mexico, 

 bordering the sea-coast. He did not see it in Tehuantepec; but it was quite common at San Bias 

 and Santiago river. A specimen obtained at Mazatlan by J. Xantus, and now in Mr. O. Salvor's 

 collection, measures — culmen 1-8 inch, height of bill at base 0*58, wing 9'9, tail 6'5, tarsus P65. I am 

 not quite sure if the present species is really the C. mexicanus of Gmelin ; but it certainly is the species 

 referred to by Schlegel (Note sur le genre Corvus, p. 11, pi. i. fig. 25) under that name. 



6220. C. leucognaphalus, Daud. (Tr. d'Orn. ii. p. 231). I do not possess a specimen of this bird, which is 

 stated by Professor Baird to be " violaceous black, the feathers round the neck, on the breast, and sides 

 pure white below the surface. Wing 12"5 inches, tail 9'0, culmen 2-45, depth of bill 0"95, tarsus 2.15." 

 It inhabits Porto Rico. 



6221. C. erythrophthalmus, P. v. Wiirt. (Naum. 1852, ii. p. 54). This species is described as being unlike 

 C. americanus, larger than C. corone, and having a fiery red eye. It is a fruit-eating species, and is 

 gregarious, large flocks being seen. It inhabits Haiti. 



6222. C. cryptoleucus, Couch (Pr. Ac. Nat. Sc. vii. p. 66, April 1854). This species differs from the common 

 Raven merely in having the base of the feathers round the neck, on the back, and breast pure white. 

 Whether this should be considered sufficient to give it specific rank is, I think, somewhat doubtful, as I 

 observe that it is not very uncommon to find that the bases of the feathers on the neck, at least, are 

 white. I have examined a specimen of C. affinis in which this white is very much developed all round 

 the neck. 



6223. "C. violaceus, Porsten, MS." Bp. (Consp. Gen. Av. i. p. 384). It is stated by Schlegel to resemble 

 C. enca, but is much smaller. It inhabits Ceram. 



The above comprises all the Black Crows and Ravens that I know of, except one lately described by Colonel 

 Irby, which is undoubtedly a distinct species, viz. : —
