PACHYCEPHALIA. 



Eopsaltria Swains.* 



Bill moderate, with the culraea slightly depressed and straight, but curved at the tip, which is 

 emarginated; the sides compressed; the gonys lengthened and slightly ascending ; the nostrils basal, 

 lateral, membranous, with the opening rounded ; and the gape furnished with long slender bristles. 

 Wings moderate and rounded ; with the fourth and fifth quills longest. Tail moderate, and even at the 

 end. Tarsi rather longer than the middle toe, slender, and covered with broad scales. Toes moderate, 

 slender, with the outer longer than the inner, and united at its base to the middle one ; the hind toe 

 long, and nearly the length of the middle one ; the claws moderate and much curved. 



This division is peculiar to Australia, where they are seen flitting in pairs from tree to tree, perched on an 

 eminence, or examining the ground for their food, which consists of insects, &c. Their nest, according to Mr. Gould, is 

 composed of strips of bark, and wiry fibrous roots, held together exteriorly with cobwebs, and ornamented with a few 

 pieces of lichen ; the interior is usually lined with leaves, and sometimes with broad blades of grasses. It is usually 

 placed in a fork of some low tree, or in any exposed part of a bush. The eggs are commonly two in number.

Ptilochloris Sxvains.^ 



Bill moderate, broad at the base, and with the sides gradually compressed ; the culmen slightly 

 depressed and straight, but bent near the tip, which is emarginated ; the gonys long and curved upwards . 

 the lateral margins inflected and straight; the nostrils basal, lateral, membranous, and rounded. Wings 

 moderate, with the first three quills graduated, and the third quill the longest. Tail moderate, and 

 nearly even at the end. Tarsi short, but longer than the middle toe, and covered in front with obsolete 

 scales. Toes moderate, with the lateral ones unequal, and the outer longest and united beyond the first 

 joint of the middle toe ; the hind toe nearly as long as the middle one ; the claws moderate, curved, and 

 acute. 



The species recorded as belonging to this genus are peculiar to the warmer parts of South America ; but their 

 habits and manners have not been noticed by naturalists.
