GROUP I. 

 Gampsorhynchus.. 



This group consists of only one species and its geographical races ; and is 

 fl, most unsatisfactory one to have in the Timeliidce, both on account of its 

 size and structure. The colour of its eggs at once precludes it being placed 

 in the Cvateropodidce, and as Mr. Oates says " Pending a better acquaint- 

 ance, their position at present appears to be in the Timeliinee.'" 



It has the following characteristics, tail much longer than the wing and 

 greatly graduated ; a powerful hooked bill, and is chiefly noticeable for the 

 ad-ult having a considerable amount of white on the head, which it aippears 

 to require two years to assume.
