Since the publications in these Annals of a paper by the 

 present writer under the above title, a considerable amount of 

 material has accumulated which it has now seemed advisable 

 to deal with. Through the kindness of Mr. Henry Burnup, 

 as on previous occasions, I have had the opportunity of 

 examining the results of his collecting on the Natal coast, and 

 although most of the new species obtained by him are small, 

 among them are some very interesting forms, notably the 

 Clistoconcha in sign is, a Pelecypod in which the valves 

 are united all round excepting at the posterior siphonal end. 

 Other species of interest have also been sent me by Mr. F. 

 Quekett, and others obtained at Port Elizabeth by Mr. J. 

 Farquhar. Most of the larger forms of Mollusca from the 

 shores of South Africa have probably been discovered, but 

 doubtless additional small species will from time to time be 

 found. Systematic dredging around the coast will, it is 

 expected, add much to the known fauna judging from the 

 results obtained during the marine investigations by Dr. 

 Gilchrist. 



It is hoped that the present paper will bring the list of the 

 known fauna up to date. 



As an appendix to it I have added an account by Sir 

 Charles Eliot, K.C.M.G. of a few Nudibranchs also collected 

 by Mr. H. Burnup.
