Descriptions of some New Forms of the 

 Campylodisci. 



Campylodiscus emarginatus. Deby. (PL XIV., f. 73.) 



Group of Raphidae. 



Diam. of valves, otoo m.m. 



Valve distinctly emarginate, or notched at strongly incurved 

 apices. Pseudo-Raphe linear, very narrow. Rays infundibuli- 

 form, few in number (12), with very narrow funnels formed by a 

 row of dots. Stems about one-third as long as the funnels. Four 

 inter-radial, marginal beads to each pair of rays. 



This species inhabits the inland Sea of Japan. I have it from 

 Mr. Rae's collection of Challenger gatherings. It appears to be 

 very rare. 



Campylodiscus Macassarensis (Grove). Deby. 

 (PI. XIV., f. 71.) 



Group of the Raphidae, with striate area. 



Diameter of valve, o*ioi m.m. 



Diam. of area. Long diam., 0-077 5 short diam., the same. 



Length of rays, 0*023 m.m. 



Length of striae, 0*031 m.m. 



Striae, 6 in. o*oi m.m. 



Puncta, 7 in. o*oi m.m. 



The striae are in the same number as the rays, and radiate 

 from a narrow pseudo-Raphe. Striae long as compared with the
