ANOPLURORUM BRITANNIA. 239 



Ardea ; all the species are large and scarce. Only a single 

 British example has come under my notice. Nitzsch states 

 the number of segments in the abdomen is ten, I can 

 discover only nine, either in this species, or L. glutinans 

 from Cathartes papa, which are the only two I have had the 

 opportunity to examine.
