100 L. A. BORRADAILE. 



Genus Philosda, Latr. 1803. 



16. ? Philosda gracilis, Budde-Lund, 1879, var. 



The collection contains specimens of a Philosda taken in several different localities, 

 but unfortunately all more or less damaged. They are at all events allied to P. gradlis 

 (Budde-Lund Prosp. 2, 1879, and Isop. Terrest, p. 220, 1885), but differ from the descrip- 

 tion given by the author of that species in the following points: 



1. The inner ramus of the uropod, though well-developed, is shorter than the outer. 



2. The fifth trunk segment is no darker in colour than the rest. 



Common in damp vegetable matter throughout the group, from Mahlos to Addu atoll. 



17. Philosda, sp. 



Damaged specimens of a Philosda from Hedufuri, Mahlos atoll. 



Family Armadillidiidae. Genus Gubaris, Brandt, 1833.

 Addu and probably also other atolls. 



With the exception of the new species, all the above crustaceans are Indo-Pacific in 

 distribution. The only feature of interest in this respect exhibited by the collection is 

 the absence from Addu of several species found in the more northern atolls.
