vei'diter, while the crimson spots were as deep-coloured as 

 usual. 



Genus Calorhamphus, Lesson. 



Differs from Bucco in having no vivid colours, nor vibrissse 

 surrounding the bill ; the upper mandible of which is somewhat 

 acutely carinated above, having the ridge continued backward to 

 the forehead, and of an arcuated form, its extremity curving over 

 that of the lower mandible ; sides of the bill smooth and flat, 

 continued backward to the angles of the gape. Wings having 

 the third, fourth, and fifth primaries subequal, the second shorter, 

 and the first but half the length of the third. Kest as in Bucco 

 (so far at least as external characters are concerned). But one 

 species is known. 



C. LATHAMi ; Bucco Lathaiiu, Gmelin ; C sanguinolentus, 

 Lesson ; Micropogon fuliginosus, Temminck ; Mcgalorhynchus 

 sjnnosus, Eyton. Unkat Besea, Penang ; Avvpis, Sumatra. 

 Length about 7 in., of wing 3f in., and tail 2 in. ; bill to forehead 

 1 in. — Colour deep brown above, with slight greenisli margins to 

 the feathers of the back and the upper tail-coverts ; stems of 

 the coronal feathers thickened and prolonged into soft spines ; 

 below somewhat glistening 3'ellovvish white, passing to ruddy- 

 brown on the throat. Bill blackish in the presumed males, 

 carneous in the presumed females ; legs coral-red. Young 

 similar, but with a smaller bill, and the greenish edges to the 

 feathers more developed and showing on the under parts. 

 Common in the Malayan peninsula and in Sumatra. We know 

 nothing of its habits. 



Note. — Besides the six species of Bucco here noticed as 

 inhabiting the Malayan peninsula, there are several others in the 

 neighbouring islands of Sumatra and Java, certain of which ma}' 

 yet be discovered in the peninsula, esi)eciall3' in the more elevated 

 forests of the interior. Such are B. javensis, Horsf. (v. kotoreas, 

 Tem.) ; B. mystacophanes, Tern. ; B. fuscicapillus, Urapiez ; B. 

 tristis, Drapiez ; B. Rafflesii, Lesson ; B. oorti, Tem. ; B. roseus, 

 Cuv. (v. roseicollis, Horsf.) ; B. australis, Horsf. (v. gularis, Tem.), 

 and probably others with whose names we are unacquainted, if 

 some of those mentioned be not doubles emplois. In the Ten- 

 asserim Provinces, Dr. lielfer states the existence of five species,*
