In Tut anus calidris there is a slender vinculum, and, in 

 addition, the flexor hallucis gives off a special slip to the 

 branch of the flexor commnnis which supplies the second 

 digit. The arrangement, in fact, is like that in Scopus, in 

 many Accipitres, &c. In the Parridse, on the other hand, the 

 tendons blend early upon the ankle, and in those that have 

 been examined no branch to the hallux has been discovered. 



Chiunis alba has the deep flexor tendons of Totanus. 



In all Charadriidae the ambiens is present. The genera 

 Charadriiis, Calidris, Gambetta, Gallinago, Limosa, Ma- 

 chetes, Scolopax, Strepsilas, Totanus, Triuga, and VaneUnx 

 have the reduced formula AXY + . 



In Hcematopus, Hiinantopus, Recurvirostra, JEgialitis, 

 Nitmenius, there is the full formula ABXY+ ; so, too, in the 

 representatives of the remaining families of the Charadrii, 

 with the sole exception of the Australian thickknee, Bnr- 

 rliinus, and some (Edicnemus, which have the formula BXY + . 



With the exception of the Parridae (q.v.) the charadrii- 

 form birds have well-developed caeca. The intestinal mea- 

 surements of a few types are as follows :
