 worth, I was told, twent3-five shillings each. 



Here I found two pairs of the sheathbill ( Chionis 

 alba), a bird whose place in the system has puzzled 

 ornitholog"ists. It has been variously considered as 

 being" one of the g'allinaceous birds, the pig-eons, the 

 waders, and even as belonging" to the web-footed 

 order. Its habits are those of the 03'ster-catchers,* 

 however different the form of the beak, which in the 

 sheathbill is short, stout, and pointed, and en- 

 veloped at the base by a waxy-looking- sheath. Its 

 feet are like those of a g'allinaceous bird, yet one 

 which I Avounded took voluntarily to the water and 

 swam off to a neigiibouring- point to rejoin its mate. 

 Cuvier, besides erroneously mentioning- that it is a 

 native of New Holland, states that it feeds on car- 

 rion • the stomachs of two which I examined con- 

 tained sea-weed, limpets, and small quartz pebbles. 

 The people here call it the rock-dove, and from its 

 snow-white plumag'e it forms a conspicuous object 

 along- the shores. 



We resumed our homeward voyag-e on July 25th, 

 and thirty-six days afterwards crossed the equator 

 in 24° west longitude. The last pintado left us 240 



* When the above was written I had not seen the remarks on 

 Chionis by M. Blainville, whose anatomical investigation assigns 

 to it precisely the same position in the system — or next the 

 oyster- catchers — which appeared to me to have been indicated by 

 its habits. — Voyage de la Bonite, Zoologie, torn. i. p. 107. pi.
