most perfectly with the Tringccv, as through the Turnstones of the 

 Family Arenaridce their kinship with the Oyster-catchers of the 

 Family H(ematPpodid(Z may easily be traced. Phalaropes are most 

 nearly related to the Sandpipers ; and the Woodcocks and Gallinago 

 in their shoulder-girdles, pelves, and less so in their sterna, show 

 strong ties Avith larine stock, as in its skull does also IJceinatopiis. The 

 line from the Plovers through the Sandpipers — and Micropalama — - 

 MacrorhampJuis — to the true Snipes and Scolapax rusticola is clearly 

 indicated, and most distinct. And starting from the pluvialine center 

 again, we once more pass through the TringecB, Act/'tis, Rhyacophilus, 

 the Tatlers of the genus Totamis, through Liinosa to the Curlews. 



Some of these relationships cannot be definitely made out until we 

 are in possession of a fuller knowledge of the anatomy in 'its entirety 

 of many of the types which have been named in this memoir. At 

 the present writing I am engaged upon preparing a provisional scheme 

 of classification of Aves as a Class. In it I place the Chara- 

 DRiiFORMES (IX. ) between the Lariformes and the group containing 

 all the ralline types. They are then arranged in the following manner.
