tion in the Old and New World. The Boat-bill 
(Cancroma cochlearia), so called from its capacious 
beak—a native of South America—is another remark- 
able member of this order. ‘The sub-family Scopine, 
consists of a single species, Scopus umbretia, but that a 
very remarkable one; it 1s known as the Hammer 
Head, from the curious appearance presented by its 
beak and long occipital crest, and constructs an 
enormous nest, placed in a tree or on a rocky ledge, 
flat-topped and clay-lined, which is said to serve for 
many years. 
The third family, Ciconirp#, contains the Storks 
_and Cranes. Of the former the Black Stork (Ciconta 
nigra) is an example, but the well-known White 
Stork (C. aléa) is also an occasional migrant to this 
county; though never more than a visitant here, it 
is abundant and breeds in Holland ; the family is for 
the most part confined to the Old World, one species 
only being found in South America. Tantalus 
leucocephaius, the so-called Indian White-headed Wood 
Ibis, belongs to this group. ‘There are five species 
of Zantalus found in North and South America, 
also in India, where they frequent river banks and 
swamps, feeding on fish. Azastomus, of which genus 
there are two species inhabiting similar localities to 
the preceding, are said to feed chiefly on a species 
of freshwater mussel (Uzz0), the shells of these they 
break between their mandibles, which in course of 
time become worn away, and the singular appearance 
noticed in the specimen of A. oscitans here seen is the 
result. The fourth family is restricted to the Spoonbills 
(/latalea), beautiful birds with singular spatulate 
bills; one is a well-known European bird, and an 
annual visitant to this county, where it formerly 
bred. ‘There are other species found in the Old and 
New World (five in all), one of these, the lovely
