I have lately obtained a single Bogota skin of a bird of this genus, 

 to which (as I caunot associate it with any of the already-described 

 species) I have given a new name. From S. caudacutus of Brazil 

 and S. tnejsicamts (P. Z. S. 1856, p. 290) of Mexico and Guatimala, 

 it differs in the want of the bright rufous colouring in the rump and 

 fore neck. In this respect it would seem to resemble Hartlaub's 

 S. guatimalensis (Rev. Zool. 1844, p. 370), but that bird is said to 

 be of the size of <Š. caudacutus, to which the present species is eon- 

 siderably inferior in diraensions. 



27. Rhimamphus c^ruleus (Wils.), Am. Orn. pi. 15. fig. 7. 



1 have lately acquired two Bogota specimens of this in imperfect 

 plumage.

 In Mr. Lawrence's Bogota coUection.

M. Parzudaki's coUection contains an immature malė of this 

 species from Bogota. 



31. Pachyrhamphus pectoralis, Sw. An. in Men. p. 288. 



A single skin from Bogota in my coUection agrees with the 

 Cayenne bird. 



32. Pachyrhamphus griseus (Bodd.), PI. Enl. 687. f. 1. 



I have seen several Bogota skins of this bird. I likewise possess 

 examples from S. Martha, Trinidad, and Cayenne. 



33. Cephalopterus ornatus, Geoffr. 



Mr. Lawrence has a fine example of this bird in his Bogota col- 

 lection. 



34. Cyanocorax turcosus, Bp. Compt. Rend. Ac. Sc. Par. 

 (1854). 



I have a Bogota skin of this species received from MM. Verreaux. 

 It is very closely allied to the better-known C. arjnillatus, but may 

 be distinguished by its rather larger size, the more greenish tinge 

 of the plumage, and brighter blue of the throat.
