176 Mr. E. Blytli on some new species of Birds 



with ferruginous ; white on the chin." The most conspicuous 

 feature of the bird before me is its cinnamon-coloured crown and 

 hind-neck, next to its gigantic size and generally robust propor- 

 tions. 



I lately described another fine heron from Arracan, which, in 

 course of time, I shall probably also obtain here, by the name 



A. fusca, nobis. Size of the larger specimens oi A. cinerea, 

 but more robustly formed, with a much longer bill, the lower 

 mandible of which inclines conspicuously upward towards its ex- 

 tremity. Length of closed wing 17 in. ; of bill to frontal feathers 

 6| in., and to gape 8:^ in. ; bare part of tibia 2^^ in. ; tarsus 6§ in. ; 

 middle toe and claw 4^ in., and hind toe and claw 2~ in. Ge- 

 neral colour blackish or dusky tinged with ashy, with the acu- 

 minated portion of the dorsal and lower nuchal feathers whitish 

 gray, contrasting with the rest ; crest of very slender elongate 

 plumes, the longest measuring 7^ in., of a whitish colour to near 

 their base ; throat white, tinged with rufous inferiorly ; under 

 parts dusky gray ; bill and feet black, the lower mandible whitish 

 along its ridge.
