and below eye slaty blue and white behind eye; naked throat pale 

 blue, white over angles of jaw. 



The female taken at Lay Song Hong is immature, but it is in adult 

 plumage. Dr. Abbott records the color of this specimen as: Iris 

 orange, a narrow yellow ring externally; bill white, black at base, 

 casque yellowish; feet black; naked skin about eye slaty blue; gular 

 pouch fleshy white, behind angles of jaw slaty blue. 



Dr. Abbott records the weight of two males as 2K and 2% pounds, 

 and of the unsexed specimen from Tenasserim as 2}^ pounds. 



Robinson and Kloss " record it from Kao Ram, 1,200 feet, Nakon 

 Sritamarat; Baker ^^ from Tung Song. Ogilvie-Grant ^^ and Baker ^^ 

 state that the sexes are alike, but apparently adult sexed females in 

 the United States National Museum from Sumatra and Borneo do 

 not bear this out. The female is darker than the male and the bill 

 horn color (in skin); the casque, the commissure at the base of the 

 upper mandible, and the base of the lower mandible only are black, 

 varying somewhat in individual specimens. In the adult male the 

 bill is entirely black. 



The four males from Trang and one male from Tenasserim are 

 darker below than four males from Sumatra. The Tenasserim male 

 is darker below than the Trang series. Two males from Borneo 

 resemble the Sumatran specimens. The mainland bird seems to be 

 somewhat larger also. It seems to me it is well worthy of being 

 recognized as a race. 



Four males from Trang measure: Wing, 360-370 (364.5); tail, 

 295-330 (315); culmen with casque, 143.5-158 (150.6) mm. One 

 male from Tenasserim: Wing, 370; tail, 330; culmen with casque, 

 160 mm. Three males from Sumatra: Wing, 346-355 (350.7); tail, 

 300-305 (301.7); culmen with casque, 152-159.5 (155.5) mm. 



The range would be the Malay States north through Peninsular 

 Siam to southern Tenasserim. Anorrhinus galeritus galeritus (Tem- 

 minck) should be confined to Sumatra and Borneo.
