332 ZOOLOGICAL GEOGRAPHY. [part ni. 



a genus of Ceciliadae, is peculiar to the Khasya Hills ; Tylo- 

 tritron (Salamandridse) to Yunan in Western Cliina, and perhaps 

 belongs to the Palsearctic region. 



Of the tail-less Batrachians, Glyplwglossus is found in Pegu ; 

 Xenophys in the Eastern Himalayas; while Calhda, Ixalus, 

 Rhacophorus, Hylura7ia, Oxyglossus, and Phrynoglossus, are com- 

 mon to the Himalo-Chinese and Malayan sub-regions. 



Of the lizards, Colotes, Barycephalus, and Hinulia, — and of 

 the Batrachia, Bvfo, — are found at above 11,000 feet elevation in 

 the Himalayas. 



Insects. — So little has been done in working out the insect 

 faunas of the separate sub-regions, that they cannot be treated 

 in detail, and the reader is referred to the chapter on the dis- 

 tribution of insects in the part of this work devoted to Geogra- 

 phical Zoology. A few particulars may, however, be given as to 

 the butterflies, which have been more systematically collected in 

 tropical countries than any other order of insects. The Hima- 

 layan butterflies, especially in the eastern portions of the range- 

 in Assam and the Khasya Hills — are remarkably fine and very 

 abundant; yet all the larger groups extend into the Malayan 

 sub-region, many to Ceylon, and a considerable proportion even 

 to Africa and Austro-Malaya. There are a large number of 

 peculiar types, but most of them consist of few or single sj)ecies. 

 Such are Neope, Orenoma, and RhapUic&ra, genera of Satyridse ; 

 Enispe, (Morphidie) ; Hcstina, Penthcma, and Abrota (Nympha- 

 lida;) ; Dodona (Erycinidffi) ; Ilcrda (Lyccenidce) ; Calinaga, Tcino- 

 pal'pus, and Bhutanitis (Papilionidce). Its more prominent fea- 

 tures are, however, derived from what may be termed Malayan, 

 or even Old World types, such as Euplcca, among Danaidse ; 

 Amathusia, Chrome, and Thaumantis, among Morphida? ; Euripus, 

 Diadema, Atliyma, Limenitis, and Adolias, among Nymphalidoe, 

 Zemeros and Taxila among ErycinidcC ; AmUypodia, Miletus, 

 Ilcrda, and Myrina, among LycsenidaB ; Thyca, Prioneris, Dercas, 

 Ipliias, and Thestias among Pieridse ; and Papilios of the 

 " Amphrisius," " Coon" " Philoxenus," " Protenor," " Paris," and 

 " Sarpedon " groups. In the Himalayas there is an unusual 

 abundance of large and gorgeous species of the genus Papilio,
