that word and Jacamar. There can be no question, indeed, that Levaillant is right in this 

 observation. If any division is to be made of the genus Bucco as here constituted, it should 

 take place at this point in the series, and should embrace this and the four following species, 

 which are remarkable for their compressed bills, reminding one, as Messrs. Cabanis and Heine 

 have pointed out, of the Kingfishers of the genus Carcineutes. Nystalus, as proposed by the 

 same authors, would seem to be the proper generic term to be used for these birds, if distin- 

 guished from Bucco proper. 



After Levaillant, Lichtenstein appears to have been the next author who became acquainted 

 with this species. Lichtenstein described it in 1823 in his list of duplicates of the Berlin 

 Museum under the new name Bucco somnolentus. But the more accurate Wagler, in his ' Systema 

 Avium,' published four years later, showed that this term was a mere synonym of Bucco (or, as 

 he called it, Capito) maculatus; and the latter specific name has been generally adopted by 

 subsequent writers. 



A good figure of this species is given in Swainson's unfinished work on the Birds of Brazil, 

 the plates of which were published in 1841, and are sometimes quoted as his 'Ornithological 

 Drawings.' Swainson's figure was probably taken from examples obtained by himself during his 

 travels in Brazil. 



Bucco maculatus, so far as I can ascertain, seems to be restricted to the northern portion of 

 the wood-region of the coast of South-eastern Brazil, and to have rather a limited range. In the 

 neighbourhood of Bahia it is certainly abundant, examples of it being commonly met with in 

 collections of bird-skins imported from that city, and several specimens obtained by the late 

 Dr. Wucherer near Bahia being in the cabinets of Messrs. Salvin and Godman. It does not, 

 however, appear to occur much further south. Prince Maximilian of Neuwied did not meet with 

 it during his travels in the province of Bahia and adjoining districts ; nor did Natterer obtain it 

 in the southern provinces of Brazil. Dr. Burmeister, likewise, failed to meet with this species, 

 and expresses his opinion that it is confined to the environs of Bahia and does not penetrate into 

 the interior. 



In Mato Grosso and in the adjoining districts of Bolivia the present species is replaced by 

 the nearly allied B. striatipectus. 



I subjoin a list of the specimens of Bucco maculatus in my collection and that of Messrs. 

 Salvin and Godman : —
