purposes of profit. There are three well-marked species of 

 Nandus, all confined to southern South America, ranging from 

 central Brazil to southern Patagonia. Darwin's Nandu {Pteroc- 

 nemis darwini) is found only in Patagonia. It is smaller than 

 the common Nandu {Rhea americana), and otherwise different. 

 A specimen of the latter may be seen in Case J- 



The Emus (family DromaiidcR) number only two species, and 

 inhabit Australia. Like the Ostriches and Rheas, they are em- 

 phatically birds of the plains. The Emus have the wings 

 extremely rudimentary, the wing feathers being reduced to mere 

 spines. The fossil remains of an extinct species have been found 

 in India, showing that formerly the Emus had a much wider range 

 than they now have. 



The Cassowaries (family Casi/ariidcE) have a very restricted dis- 

 tribution, being mainly confined to New Guinea and the neigh- 

 boring Papuan Islands, a single species only of the ten commonly 

 recognized being found in North Australia. Several of the species 

 are each confined to single small islands. Like the Emus, the 

 Cassowaries have very rudimentary wings, in which the flight 

 feathers are represented by horny spines. They are remarkable 

 for the horny casque or helmet surmounting the head, and the 

 brilliantly colored naked skin and wattles about the face. The 

 species much resemble each other, and inhabit dense forests or 

 thick scrub. The group is represented by a single specimen in 

 Case K. 



The Moas (family Dinornithidcc, sometimes recognized as an 

 order, Itnmanes) are an extinct group of Struthious birds, formerly 

 inhabiting New Zealand and portions of Australia. The date of 

 their extinction is comparatively recent, there being some evidence 

 that they existed in New Zealand when the Maoris, by whom 

 they were probably exterminated, migrated to that island. They 

 are of special interest in many ways, supplying the link between 

 the Kiwis and the Ostriches. Their wings were rudimentary, and 

 their hind limbs massive. About fifteen species are recognized, 

 differing so greatly in form and size as to be referred to several 

 genera. Three and a half tons of their bones have been found 

 at a single locality, representing, it is estimated, about four hun- 

 dred skeletons; other large deposits have been found at other
