Measurements. — Males: Wing, 134-146.5 (average, 141.3) ; tail, 

 84-99 (average, 90.2) ; exposed culmen, 70-82.5 (average, 74.1) ; 

 tarsus, 17-20.5 (average, 18.1). Females: Wing, 142-145 (average, 

 143.5) ; tail, 86-87.5 (average, 86.8) ; exposed culmen, 74; tarsus, 

 17.5-19 (average, 18.3) mm. 



Type-locality. — Calcutta, India. 



Geographical distribution. — Eastern Bengal, India, to Arakan, 

 Tenasserim, and Lower Siam. 



This very distinct species seems to ho subject to little, if any, 

 geographical variation in either size or color, for specimens from 

 Lower Siam and the Mergui Archipelago are just like those from 

 India. There appears to be little distinction of size and none of 

 color between the sexes. Immature birds are distinguishable by 

 dusky tips on the ochraceous feathers of neck and lower parts. 



The following specimens of this species have been examined: 



RAMPHALCYON MELANORHYNCHA MELANORHYNCHA (Temminck). 



Ucedo melanorhynoha Temminck, Planch. Col., IV, 1S26, pi. cccxci 

 ( Celebes). 



Specific diameters. — Scapulars, middle of back, wings, and tail 

 brown, tinged with greenish or bluish; rest of plumage cream color, 

 becoming buff or ochraceous on the posterior lower surface, and dusky 

 on the sides of head and forehead; bill wholly black. 



Measurements. — Wing, 140-154 (average. 148.6) ; tail, 87-101 

 (average, 91.2) ; exposed culmen, 74-84 (average, 79) ; tarsus, 15-17 

 (average, 15.6) mm. 



Type-locality. — Celebes. 



Geographical distribution. — Togian Islands, Celebes, and the adja- 

 cent islands of Leinbeh, Banka, and Manado tua. 



The bill in this form is nearly always entirely black, but some- 

 times in specimens from middle Celebes there appears a small red 

 spot at its base. 



This bird is found probably throughout Celebes, since it has been 

 recorded from the northern, western, middle, and southeastern por- 

 tions of the island. 



Only one specimen has been examined, an adult male (A. N. S. 

 Phila., No. 50028) collected by C. Hose on Mount Masarang, Celebes,
