182 ORNITHOLOGY AND OOLOGY. 



FAMILY PARID^E. 



Bill generally short, conical, not notched nor decurved at tip ; culmen broad and 

 rounded, not sharp-ridged at base ; nostrils rounded, basal, and concealed by dense 

 bristles or bristly feathers ; loral feathers rough and bristly, directed forwards ; tarsi 

 distinctly scutellate; basal joints of anterior toes abbreviated, that of middle toe 

 united about equally for three-fourths its length to the lateral, in Parince forming a 

 kind of palm for grasping ; outer lateral toe decidedly longer than the inner ; prima- 

 ries ten, the first much shorter than the second ; tail feathers without soft tips. 



The two sub-families may be thus distinguished : 



Parince. Body compressed ; bill shorter than the head ; wings rounded, equal 

 to or shorter than the rounded tail, second quill as short as the tenth; tarsus longer 

 than the middle toe and claw, which are about equal to the hinder ; soles of toes 

 widened into a palm; plumage rather soft and lax. 



' Sittince. Body depressed ; bill about equal to or longer than the head ; wings 

 much pointed, much longer than the nearly even tail ; tarsus shorter than the mid- 

 dle toe and claw, which are about equal to the hinder; plumage more compact.
