The Siberian SpoonbillSandpijjer has a most singularbill, which is much enlarged at the end, suggesting aflat-ended forceps. The Roseate Spoonljill, an entirelydifferent bird, has a somewhat similarly shaped bill, astriking instance of the occurrence of the same form infamilies which are not closely related. But probably the most remarkable instance of relation. Fk 11.—Bill of Spoonbill Sand-piper. (jSatural size.)
