BrCEROS ELLIOTTI*, n. sp. 



This species resembles the last one very closely, but it is much larger and wants tlie white- 

 bordered crest; otherwise the description I have given of the plumage of B. malayanus will do 

 for this one. In my only specimen the bill has evidently arrived at maturity, and is perfectly 

 white ; the posterior portion of the casque covers a portion of the vertex, and is eight tenths of 

 an inch higher than the occipital plane, its posterior edge being one and seven tenths of an inch 

 behind the nostril when measured in a straight line ; a ridge proceeds from the nostril, and marks 

 where tlie true culnien would be if the casque were absent ; this ridge ends where the culmen 

 begins; two more ridges run almost parallel to it and above it, thereby causing two corresponding 

 furrows ; a third fuiTOw is formed by the uppermost ridge and the swell of the casque, which 

 commences to bulge above it ; a fourth ridge is thus formed, but which is much broader and 

 more rounded than the lower ones, and is bounded along its superior edge by a fourth furrow.
