tion the toes are said to be cloven, with the outer 

 connected to the middle by a membrane at the base 

 alone ; and his figure scarcely exhibits even this slight 

 connexion. In the same figure the black tip of the 

 bill is made much too long, and is arched in a way that 

 bears no resemblance to the bird itself; the whole head 

 is represented as covered by a rough yellow skin, which 

 exists in no specimen that we have seen ; and the 

 general colouring is much too dark. The learned 

 author corrected, as we have before remarked, in his 

 General History of Birds, some of the defects of his 

 first description, but he still suffered a considerable 

 portion to remain. The head is there said to be 

 " covered, as far as the eyes, with a rough skin or 

 cere," and is so represented in the amended copy of 

 the plate ; but the specimen in the British Museum 

 referred to by no means justifies this assertion, for the 

 cere or naked skin does not extend in it beyond the 

 point which we have already indicated in our character 

 of the genus. The toes are properly said to be " united 

 by a membrane half way from the base," and a slight 

 but very insufficient addition has been made to this 

 part of the figure. But all the other errors of the 

 original are retained in the amended copy, except that 

 the general colouring being lighter is more consonant 

 to truth, and allows the blackish spots upon the upper 

 surface and wings to be more distinctly seen. Of the 

 two figures that have since been published, M. Tem- 

 minck's is decidedly the best, the only defect in it 

 being the light yellow colouring of the legs, which, as 

 is truly said in his description, should be of an orange 

 hue. In his description it is farther said that a wrin- 

 kled yellowish skin covers the forehead, but this is 

 borne out neither by the figure nor by the fact, and 

 appears to have been inconsiderately adopted from 

 Dr. Latham. M. Vieillot has fallen into the same
