The first communication referring to the One-wattled Cassowary is the followiuf 

 editorial note in 'The Ibis' for 1860, p. 193: — " Mr. Blyth in his last letters (dated 

 C'alcutta, Jan. 8th & 21st) speaks of an apparently new species of Cassowary (Casuanus) 

 in the aviary of the Babu Rajendra Mullick of Calcutta : ' It has a yellow throat, a 

 single yellow throat-wattle, and a long strip of naked yellow skin down each side of the 

 neck. In its present (first) plumage, it is of a much lighter colour than the young

 much smaller species.' " 



In the ' Journal of the Asiatic Society of Bengal,' Blyth first published the 

 name : — •

 single pendulous caruncle in front of the neck. Specimen apparently more than 

 half-grown, and much paler in tlie colouring of its plumage than specimens of the 

 same age of the common C. galeatus, two fine examples of which are associated with . 

 it in the same paddock. In lieu of tlie two bright red caruncles of the latter, the new 

 species has but a single small oblong or elongate oval yellow caruncle, and the bright 

 colours of the naked portion of the neck are differently disposed. The cheeks and 

 throat are smalt-blue, below which is a large wrinkled yellow space iu front of the 

 neck, terminating in front in the oval button-like caruncle, and its lower portion being 

 continued round behind, while on the sides of the neck the yellow naked portion is 

 continued dowu to its base, the bordering feathers mure or less covering and concealing 

 this lateral stripe of unfeathered skin ; on the hind part of the neck the bare yellow 

 skin is not tumous and corrugated as in the Common Cassowary, where also this part
