FINAL ADDENDA AND CORRIGENDA. 



IN looking through Prof. Brim's slides, I have discovered 

 what I consider a distinctly new form, which I have much 

 pleasure in dedicating to this obliging gentleman. I have called it 

 Campylodiscus Bruneanus, Deby, sp. n. 

 Brun. Collect , slide No. 2864. 

 Group of the Raphidae. 



Dime?isio)is : — 

 Diat. of valves, o - o59 m.m. 



Valves slightly oval. Raphe linear. Rays numerous (about 

 100) and close set (7 to 8 in o'oi m.m.), distinctly crenato-punc- 

 tate. Puncta at variable distances (from 5 to 6 in 001 m.m.). 

 No marginal beads. Outer rim finely striate. 



This species differs principally from C. Kutzingii, Bail C. 

 striolatus, Grun.), by its punctate rays. It is from Sendai, Japan.

Replace last paragraph on page 46 by the following : — 



"I consider Nos. 16, 39, 63, 64, 78, to be doubtfully distinct 



forms; and Nos. 5 and 23 as probably not belonging to the genus 



Campylodiscus." 



Page 53, No. 48 read: — "Blank spaces lunate, not continu- 

 ous all round the Area," etc.

 placed immediately after C. divosus, Brun, on page 60.
