(With 39 text-figures.) 



The Chilopoda Geophilomorpha described up to date from 

 India (including Burma) are the following : — 



Lamnony X spissus, Wood. Burma. 



,, castaneiceps, Haase, Andamans. 



,, punctifrons (Newp.), from many localities. 



Orphnaetis brevilahiatus (Newp.), from many localities. 



Eucratofiy X meinertii (Focock). Mergui Archipelago ; Burma, 

 etc. 



Himantosoma typiaim, Pocock. Mergui Archipelago ; Burma. 

 ,, porosum, Pocock. Burma. 



Disargus strialus (Pocock). Madras. 



Polyporogasfer indicus (Mein.). Kulu. 

 ,, insignis (Mein.). Kulu. 



? Himantaricun doriae, Pocock. Burma. 



In the collection of the Indian Museum kindly sent me for 

 examination by the Director of the Zoological Survey of India 

 I have found specimens of 19 species or varieties, which are des- 

 cribed in this paper with some others of the same genera or related 

 genera of the Oriental and Malaysian regions preserved in my 

 collection. 



The rich material of the genus Lamnonyx has permitted me 

 to make a revision of the species and related genera of the group, 

 and has shown that L. punctifrons, Newp. from India, or at 

 least the form considered as such by me, is restricted so far as we 

 know to the East of South India ; L. insulans (Lucas), which is 

 distributed through tropical Africa, extends its range to W. India 

 and in a varietal form to South India and Malaysia ; L. maxillaris 

 (Gcrv.) is a cosmopolitan species in tropical and subtropical regions 

 and has also been introduced into hot-houses of Europe. The 

 remainder of the species of the genus Lamnonyx have a restricted 

 area of distribution. 



The genus Lamnonyx is represented in India by nine forms 

 (species and varieties) out of 22 described up to date, and is a 

 prevalent genus both for number of species and frequency of 

 specimens. 



After Lamnonyx the genera Polyporogaster and Mesocanthus 

 have respectively three and four species in India, while the first
