The Myriopoda of Burma, Pt, IV. Report upon the Polydesmoidea collecleil 

 by Sig. L. FEA, Mr. K. W. GATES and others, by r. i. pocock of tlie Britisli 

 Museum of Natural History. 



The richness in new forms of the Burmese Polydesmoidea 

 amassed by Sig. L. Fea and Mr. E. W. Gates may be gathered 

 by a glance through the succeeding pages which show that only 

 three of the species have ever been previously described. One 

 of these is the ubiquitous Orlhomorpha coarctata of Saussure; the 

 others, namely Orlhomorpha karschii and PLatyrrhachus andersonii, 

 were obtained by Dr. John Anderson in the Mergui Archipelago, 

 off the coast of Tenasserim. The latter of these was identified 

 for me by Dr. Karsch as Acanliiodesmus pilipes of Pet.; but I 

 have decided on the present occasion to give it a new name on 

 the grounds that the geographical distribution of the Tenasserim 

 and Bornean forms must be correlated with some structural 

 features of specific importance, which were overlooked by 

 Dr. Karsch. 



I have ventured to propose several new genera ; but whether 

 or not they will withstand the progress of knowledge remains 

 to be seen. All that I can say for them now is that they seem 

 to represent natural units, which, so far as the material at my 

 disposal shows, are distinctly recognisable within the limits of
