1861.] DR. p. L. SCLATER ON BIRDS FROM JAMAICA. "9 



45. Ch^tura zonaris (Shaw).— Aca7ithi/Iis collaris, Gosse, B. 

 Jam. p. 51. 



Several examples, not differing essentially from continental speci- 

 mens. I have seen the same bird from S. Domingo. 



46. Lampornis porphyrura (Shaw). — Lampornis mango, 



47. PoLYTMUs CEPHALATER, Bp. Consp. p. 72.—Trochilnsno- 

 lytmus, Gosse, p. 97. 



48. CoccYzus SENicuLus (Linn.) : Gosse, p. 281. 

 One specimen from Savannah la Mar. 



49. PiAYA PLuviALis (Gm.) : Gosse, p. 277. 



50. Crotophaga ani, Linn. : Gosse, p. 282. 



Adnlts and nestlings. The sexes are alike, the sharp keel of the 

 upper mandible being equally developed in both. 



51. Centurus radiolatus (Wagl.) : Gosse, p. 271. 

 One ex. 



52. CoNURUS NANUS (Yig.). — Psittacara nana, Vig, Zool, 

 Journ, V. p. 273. — C.Jlaviv enter, Gosse, p. 263, 



Several ex. of both sexes, between which there is no external dif- 

 ference. 



53. Chrysotis agilis (Linn.) : Gosse, p. 266. 



Two ex., of which the female, as marked, is rather smaller in di- 

 mensions. 



54. Chrysotis collaria (Linn.). — Ps. coUarius, Linn. S. N. 

 p. 149.— P. leucocej}kalus, Gosse, p. 269.—Pioiius vinaceicoUis. 

 Lafr. R. Z. 1846, p. 321, 



Two ex., of which that marked female has the white front very 

 narrow. This species, as I have already pointed out, is represented 

 in Cuba by C. leucocephala, in S. Domingo by C. sallcei, and in Porto 

 Rico hj Chrysotis vittata (see P. Z. S. 1857, p. 225). When these 

 islands formed one piece of laud the region was, no doubt, occupied 

 by a common progenitor, a certain Chrysotis prisca, from which these 

 four birds have become modified during their descent. 



55. Hypotriorchis columbarius (Linn.) : Gosse, p. 17. 



56. Strix pratincola, Bp. : Gosse, p. 23. 



This seems to bemorehke the N. American Strix pratincola than 

 to the Cuban Strix furcata, though I should mention that I have 

 not had an opportunity of making an accurate comjiarison of speci- 



mens.
