Manks or sides of body are the parts approximately covered by 

 the closed wing. 



Axillaries are the lengthened feathers springing from the axilla 

 or region beneath the base of the wing. 



Supplementary bristles or hairs are those springing from the side 

 of the forehead in front of the rictal bristles. 



Nasal bristles or hairs are those springing from the front of the 

 forehead and covering the nostrils. 



The measurements in this work are invariably in millimetres, nnd 

 are taken thus : 



Length. The distance from the tip of the bill to the tip of the 

 longest tail-feather, unless otherwise stated. 



Tail. The distance from the root of the tail, generally indicated 

 both in the fresh aud dried state by the presence of a 

 piece of flesh on the underside, to the tip of the longest 

 feather. 



Wing. The greatest distance from the bend of the wing to 

 the tip of the longest primary, measured straight. When 

 the wing is curved, it is flattened out for the purpose of 

 measurement. 



Tarsus. The distance from the centre of articulation of the 

 tarsus with the tibia to the base of the middle toe. 



Culmen. The distance in a straight line from the feathering 

 of the forehead to the extreme tip of the beak.
