1. ADDITIONS TO THE MARINE ISOPODA. 

 (Plates XVII.-XXIV.) 



THE following paper contains descriptions of thirteen species and 

 one variety of Marine Isopods, all from the collections in the South 

 African Museum. One genus, ten species, and one variety are 

 described as new. One species, known only from a dried specimen 

 in the British Museum without locality, also requires the institution 

 of a new genus. The males of two species, of which only the 

 females were previously known, are described for the first time. 



In addition the records of four species already known, but which 

 were omitted from the General Catalogue of South African Crustacea 

 (Stebbing, Ann. S.A.M. vol. vi. pt. 1, 1910) are inserted. 



A note of the occurrence of lais pubescens (Dana) and the descrip- 

 tion of the male will be incorporated in a future paper along with 

 the notes on the Sphaeroniid hosts which it inhabits. 



To Eev. T. E. E. Stebbing, F.E.S., are due my very best thanks 

 for his kindly advice on several points and the addition of references 

 which I had overlooked.
