KEY TO THE SPECIES. 



Of the twenty-eight generic names already enumerated as having been applied to 

 sections of this genus, six of them may perhaps be allowed to claim subgeneric rank, and 

 the species may be ranged under them as follows : — 



Totanus. — T. glottis, T. fuscus, T. calidris, T. guttiferus, T. stagnatilis. 



Machetes. — T. pugnax. 



Symphemia. — T. semipalmatus. 



Trivgoides. — T. melanoleucus, T. flavipes, T. glareola, T. ochropus, T. solitarius, 

 T. terekius, T. hypoleucus, T. macularius. 



Heteroscelus. — T. incanus, T. brevipes. 



Bartramia. — T. bartrami. 



In forming a key to the species it is scarcely necessary to recognize more than two 

 groups. Subgenera are so very aggressive, that it is a pity to lose an opportunity of 

 snubbing them. 



The first group contains the typical Totani, which may always be distinguished by 

 their white lower backs, and the Heterosceli and Symphemia, which may be most easily 

 recognized by their unbarred dark grey axillaries.
