Sp. Ciconia marabu TEMM., PI. col. 300; from the continent of India, also 

 in Java and Sumatra; Ciconia argala TEMM. PL col. 301 ; from Senegal 

 and South Africa. Large species of storks with naked neck, which forms 

 a dependent, elongated sac below ; according to TEMMINCK the two species 

 were confounded formerly under the name of Ardea dubia or Ciconia 

 argala, which names however GRAY adduces as synonyms of the first 

 species. The loose white tail-coverts, maraftow-feathers, are sold at a high 

 price. 



Mycteria L. Bill subasceiiding. Head and neck destitute of 

 feathers. 



Sp. Ciconia mycteria TEMM., Mycteria americana L., BUFF. PL enl. 817, 

 LESS. Ornith. PI. 98, fig. 2 ; Ciconia ephippiorhyncha TEMM., Mycteria 

 senegalensiz LATH., Cuv. R. Ani., e"d. ill., Oi*. PI. 75, fig. 3. 



Scopus BRISS., ILLIG. Bill elongate, high at the base, com- 

 pressed, curved at the tip, excavated by a narrow, deep groove on 

 each side near the culmen. Nostrils placed near the base of bill 

 below the groove, narrow, linear. Face plumed. Tarsi reticulate 

 in front. Anterior toes joined at the base by membrane; hallux 

 insistent. Wings with first quill short, second, third, and fourth 

 subequal, third longest of all. Tail short. 



Sp. Scopus umbretta GM., BUFF. PL enl. 798, LESS. Ornith. PI. 69, fig. i, 

 GUR. Iconogr., Ois. PI. 53, fig. 3, hab. in Africa. 



Cancroma L. Bill long, depressed, broad, carinate above, 

 with tip narrowed, curved. Nostrils basal, approximate; groove 

 extending on each side of culmen from the nostrils to the tip. 

 Tarsi covered anteriorly with large, broad, hexagonal scales. Claw 

 of middle toe incised pectinately on the inside. Anterior toes united 

 at the base; hallux insistent, inserted on the internal side of lower 

 part of tarsus. Wings with first quill shorter, the next increasing 

 up to the fourth, fourth and fifth subequal, longest. 



Sp. Cancroma cocklearia (and Cancroma cancrophaga) L., BUFF. PL enl. 38, 

 896, LESS. Ornith. PI. 97, fig. 2, GUER. Iconogr. , Ois. PI. 52. fig. i ; the 

 boat-bill, le savacou; in Surinam and other parts of South America; this bird 

 lives on fish, like the herons, from which it differs by the flat bill, which, 

 according to the comparison of BUFFON, has the form of two spoons lying 

 one upon the other with the convex surface upwards. It is generally sup- 

 posed that there is only one species known, and that the red-brown specimens 

 are young birds; not long ago, however, it was asserted on the contrary 

 by a French voyager, E. DEVILLE, that there exist different species of
