vol. viii., p. 519), is very numerous throughout Yucatan. It is a beau- 

 tiful bird, coloured with green, blue, red, white, and yellow. Another, 

 supposed to be the Psittacus Guianensis (Gen. Lil., vol. i., p. 323), the 

 green parrot of Guiana (Gen. Syn., i., 231 ), is not so abundant as the last, 

 but still quite numerous. The specimens were procured at Ticul, and 

 some were afterward shot near Iturbide. The third species was not seen 

 in the wild state, the only specimen procured being given to Dr. Cabot, 

 alive, by the padre Curillo, of Ticul. It is the Psittacus Macao (Ind. 

 Om., vol. i., p. 82), red and blue macaw (Gen, Syn., i,, 199). 



Of the genus Ramphastos one specimen was procured, the yellow- 

 breasted toucan (Gen, Syn., vol i., p. 326), Ramphastos Tucanus (Ind. 

 Om., vol. i., p. 136). This specimen does not agree with the description in 

 Latham, but is the same as the one described by Mr. Edwards from a liv- 

 ing specimen in Lord Spencer's collection. It was procured at Uxmal on 

 the day when Dr. Cabot went down to the hacienda to operate on an Indian's 

 leg. Two or three different species were afterward seen at Macoba, but 

 Dr. C. did not succeed in killiug any of them. 



Of the genus Momotus were obtained two species ; the first, the common 

 Brazilian or blue-headed motmot ; this was quite common in Yucatan, but 

 not so common as the other, as to which it is doubtful whether it has been 

 described. It is about the same length as the blue-headed, but the tail is 

 longer in proportion to the body. The markings on the plumage are very 

 diflferent from those of the Brazilian; there is a black stripe extending 

 down from the chin to the middle of the breast, bordered on each side with 

 light blue ; a broad, light blue, almost white, stripe extends over the eye 

 from the base of the bill almost to the hind head. The general colour is a 

 sort of greenish bay ; primaries and tail light green, tipped with black ; the 

 two central feathers of the tail much longer than in the Brazilian, having 

 the shaft bare to a much greater degree, and the feather at the tip is bright 

 pale green, tipped broadly with black. 



Of the genus Crotophaga one species was procured, the lesser ani (Cro- 

 tophagi Ani. Ind. Orn., vol. i., p. 448). These were very abundant in all 

 parts of the country. 



Of the genus Oriolus, including under this denomination Icterus and 

 Cassicus, were procured five species, one of which is supposed to be new, 

 three doubtful, and one known. The male of the new species is nine inch- 

 es and a half long ; head, neck, cheeks, breast, belly, rump, tertiaries, and 

 nearly the whole length of the outer tail feathers and the lower part of the 

 third, and occasionally a stripe on the fourth, bright chrome yellow ; face, 

 throat, primaries, secondaries, back, and four, and sometimes six tail 

 feathers, black ; legs bluish ; bill black, except the base of lower mandible, 

 which is bluish ; sings finely. Female eight inches and seventh eighths 

 long; marked like the male, but not so brilliant; irides hazel. One of the 

 doubtful comes very near to Latham's description of the lesser Bonana bird
