106 Annals of the South African Museum. 



austrina, Elasmopus serrula, Hyale novae-zealandiae have been rele- 

 gated to synonymy for reasons which, I trust, will be considered sound. 



Except where otherwise stated, the specimens were collected in the 

 littoral zone at low-water mark. 



The types of all new species are in the South African Museum. 



My thanks are again due to Mr. J. H. Orton of the Plymouth 

 Marine Laboratory, Mr. F. W. Edwards of the British Museum, and 

 Mr. H. Watson of Cambridge for ti-aciugs of figures otherwise inac- 

 cessible to me; and also to Dr. Chiltou of Christchurch, N.Z., and 

 Prof. Haswell of Sydney. 



Corrigenda. I may take this opportunity of coiTecting two un- 

 fortunate mistakes in my last paper on South African Isopods (Ann. 

 S.A. Mus. vol. 10, pt. 11, 1914: Aega uroioma, u. sp. most probably= 

 A. semicarinata Miers, 1875, and DynameneUa kraussi n. sp.= 

 D. huttoni (Thomson), 1879. The latter I have confirmed by a com- 

 parison with New Zealand specimens, which I owe to Dr. Chiltou's 

 kindness. On Plate XXXVII. C. of the same paper one of the figures 

 of Jais pubescens has been inadvertantly printed upside down and 

 labelled " mxp " instead of " pip 3."
