et Coiisp. ii. p. 162) in considering it distinct rostri maculis im- 

 pressis seriatim dispositis. Several skins of it are in Capt. Beavan's 

 collection, and appear undoubtedly different from our living P. ru- 

 fescens. 



P. trachyrhynchus* appears to be often witbout the conspicuous 

 knob on the upper mandible. Probably this striking feature is 

 only developed in the adult male. This species is distributed in 

 appropriate localities all over the United States, both east and west ; 

 it is also found in Mexico, and on the Pacific coast of Gruatemala 

 (rf. Scl. et Salv. Ibis, 18.)9, p. 233, et Salvin, ibid. 1865, p. 197). 

 I trust that it will not be long before we acquire living examples 

 of this species from some of our excellent correspondents in the New 

 World. 



P. »wo/m<e (well-described in Bonaparte's 'Conspectus,' ii. p. 164, 

 under the name Onocrotalus thagus) is one of the numerous ex- 

 cellent species that is not in the Leyden Museum, and is conse- 

 quently discarded by its Director as a mere synonym of P.fuscus. 

 But after examining the specimens of this bird in the British 

 Museum, I cannot but allow, with Mr. George Gray and Prince 

 Bonaparte, that it is an excellent species, allied to P. fuscus, but at 

 once distinguishable by its larger size and darker plumage. At 

 the same time I agree with Prof. Schlegel (Mus. des P.-B. Pelecani, 

 p. 28) that Pelecanus thagus of Molina is a very doubtful synonym, 

 and prefer, therefore, to adopt Mr. Gray's appellation molincB for 

 this species. 



The species of Pelecanus, therefore, which seem to me to be 

 well founded are ten in number, and may be divided as follows : — 



a. Saccus gularis minor, gulam solam amplectens. 



a'. Lora nuda.

* I think it better to pass over Gmelin's name eryfhrorhynchus for this spe- 

 cies, although prior to Latham's. The bill is not red ; and Gmelin called it 

 eri/throrhynchiis because he mistook the vrord " rough" applied to its bill by 

 I.(atham, for roii.ge \ (See Latham, G. H. x. p. 408.)
