Introduction. 



Thanks to the untiring labours of Drs. E. Warren and C. 

 Akerman, I am able in the present contribution to add a 

 further series of new Terrestrial Isopoda to the fauna of 

 Natal and the adjacent country. 



It is evident from the work that has ah-eady been carried 

 out that Natal, indeed the whole of South Africa, possesses a 

 rich Isopodean fauna, and of the specimens collected there 

 yet remain a number of new forms, but the material at 

 present in my hands is insufficient for description. 



In the present paper figures of all the new species are 

 given, including those described in Part I (3), and I have ta 

 thank Miss Grace Edwards and Miss E. R. Burnett for the 

 care they have expended upon these. 



The new forms include a species of Ligia Fabr., one 

 belonging to the genus AlloniscusDa»(x, four new species of 

 Cubaris Brandt, and one of tlie new genus Anchicubaris. 

 In addition to these I am able to record the occurrence 

 of Philoscia muscorum {8copoli) and Porcellionides 

 pruinosus {Brandt), and some further localities for Phi- 

 loscia warreni Cllge. and P. dilectum Cllge. 



I. Description of Gp:neka and Species. 



Ligia Fahricins. 



Comparatively little has been written upon the members of 

 this interesting genus. Structurally they are easily distin- 

 guished by well-defined characters and many of the species 

 are exceedingly common and have a wide distribution. 



Hitherto the genus has not been recorded from Natal, 

 although it has long been known froui Cape Colony. Brandt 

 (1) in 1833 described very briefly the Ligia glabrata and 

 L. dilatata, and Budde-Lund (2) in 1885 described iu the 

 briefest possible manner tlie L. gracilipes.
