from 1-70 to 1*86, and that of the tail from 1 '16 to 1-45. 

 Nos. 20, 21, and 22 have also hills of equal length, -71, only 

 '01 inch longer tlian the nine preceding ones ; the wings, 

 however, vary to the extent of '09 inch, and the tails "16 inch. 

 The gradual increase in length of bill continues in Nos. 23 

 and 24, being '72 and -74 inch, from Ecuador and Veragua, 

 while the wing of the latter specimen is '06 inch shorter 

 than the Ecuador specimen, which reaches 1*90 (with but 

 one exception, the longest of all those of the examples mea- 

 sured). Nos. 25, 26, and 27 show equal bills of shghtly 

 increased length, being '75 inch, '01 longer than No. 24. 

 The wings and tails also vary, '10 and '23 inch respectively, 

 no two of the former being of equal length. Nos. 28 and 29 

 are females from Ecuador, with bills of "76 and "79 inch, and 

 wings r85 and 1*91 inch, the last being the longest of all the 

 specimens in the list; but the tails are quite short, viz. 1"21 and 

 1*24 inch; but this was to be expected from their sex. No. 30, 

 also a female, from the Rio Napo, has the bill '80 inch in 

 length, '01 inch longer than No. 29 ; but the wing is '01 inch 

 shorter than in that specimen, while the tail, again, is '03 inch 

 longer. The last specimen is a young male from Bogota, 

 with a bill of equal length with the last, but the wing and tail 

 '24 inch and '12 inch shorter respectively.
