Montagu mistook it for Ardea sequinoctialis of Linnseus ; 

 but the error was detected after it had, along with his collec-

 sions, taken by Mr. Jenyns are as follows : — 



Entire length 20^- inches; length of the bill from the 

 forehead 2-^, from the gape %\% ; of the tarsus 3 ; of the 

 naked part of the tibia 1^ ; of the middle toe, claw included, 

 2^2 ; of the tail 4 ; from the carpus to the end of the 

 wing 10.
