138 GRALLATORES. TRINGA. Kwor. 
By the Knot, which stands at one extremity of the group, 
the Tringas are allied to the genus Machetes, the bill of that 
bird being nearly straight, and resembling that of the Ruff. 
It also leads the way to the Phalaropes, the membrane which 
borders its toes being more dilated than in most of the other 
species. The direct passage to these last mentioned birds is 
probably better effected by the intervention of the T'’ringa 
semipalmata of Wi.son’s North American Ornithology, in 
which, and in the 7'ringa himantopus of the Prince of Mu- 
signano, the toes are connected by a considerable membrane 
or web. These have been separated by that eminent natu- 
ralist from the genus J’ringa, under the generic title of 
Hemipalama, and, by peculiar modifications of form in which 
birds, a union is effected with the genus Numenius, with 
which the present family commences. From the Knot to 
the Tringa subarquata (Pigmy Curlew), in which the bill 
appears to attain its utmost degree of curvature and length, 
the passage (by means of the T'’ringa maritima, Tringa va- 
riabilis, and other species) is easy and gradual.
