XXXVII. TERRESTRIAL ISOPODA.

 (Plates xxxi-xxxiii.) 



The small collection of Terrestrial Isopoda collected b}^ the 

 Abor Expedition in the foot-hills of the Eastern Himala5'as 

 and b}^ Mr. F. H. Gravel}- in Tenasserim have been placed in 

 my hands for identification and description. Unfortunately the 

 number of individual specimens is with one exception small and 

 most of them are imperfect, so that their identification has not 

 always been easy. 



The Philoscia spp. i and 2 are in all probability new. I have 

 previously seen an imperfect specimen of No. i from Saharanpur, 

 U. P. Budde-Lund in 1894 (Ann. Mus. Civ. Stor. Nat. Genova, 

 s. 2, vol. xiv, p. 612) described a species, Philoscia coeca, without 

 figures, from the Farm Caves, Moulmein. The fragmentary con- 

 dition of all the examples is, however, such that I do not feel justi- 

 fied in describing them from this material. The cosmopolitan 

 species Porcellionidcs pruinosus (Brandt) occurs in four of the 

 localities collected in. An interesting addition to cave fauna is the 

 new genus Burmoniscus Most of the specimens of Cubans are 

 immature, one from Sadyia, N. E. Assam, No. 8083/10, and 

 another from the Dawna Hills, No. 8078/10, are undoubtedly new 

 and these are here described and figured. 



Porcellionides pruinosus (Brandt). 



This species has previously been recorded by Stebbing ' from 

 Kurseong, 3,000 feet, E. Himalayas, i5-vii-07. In the present 

 collection the localities are as follows :-— 



Rotung Abor Country, 1,300 feet. 



No. 8080/ Eo. Two specimens. 

 Kobo, 400 feet. In rotten wood. 



Two specimens. 

 Kobo, 400 feet. In rotten wood. 



One imperfect specimen 

 Sadyia, N. E. Assam. Under logs. 



Two specimens. 



Philoscia, sp. i. 



An interesting form, but unfortunately all the specimens are 

 imperfect. Specimens were obtained from the following locali- 

 ties : —
