F u r c a: — Behind the claws there is an unpaired, long-haired bristle uliich is about 

 as long as the seventh or eighth claw. 



The r o d - s h a p e d organ is as described and reproduced by (t. W. Muller ; see the 

 accompanying fig. 3. 



The u p p e r 1 i p and p a r a g n a t e s are f)f the same types as in my figs. 37 and 38 

 of C. symmetrica. 



Remarks: — G. W. MtiLLEli in his work of 1908 (p. 74) points out that ('. magna, 

 Cll. JliDAY, 1906, p. 19 is not a synonym of C. magna C. ClauS; Muller writes with regard 

 to the description given by Juday: ..eher pailt sie zu Conchoecia lophura G. W. Mt'LLER". 

 The same writer, in his synoptic work of 1912, puts this species of Ch. Juday'S as a synonym of 

 C. lophura, but adds a query. It can be considered beyond doubt that C. magna Oh. Juday 

 is not a synonym of C. magna G. Glals. C'ertainly its identity with C. lofhura seems to me 

 far from impossible, but it is so uncertain that it did not seem to me proper to include the name 

 in ([uestion in the list of synonyms given above. 



To judge from Fowler's description it seems very probable that G. H. Fowler's 

 ,,Lo'phura-stage'' of (J. hyalophyUum is identical with ('. hiphura; see p. 565 above.

Shell: — The specimens investigated by me were from 2,4 to 2,7 mm. long. The 

 sculpture varied to some extent, sometimes resembling the type reproduced by G. W. MULLBR 

 for C lophura and exceedingly difficult to observe. The selvage, the glands along the posterior 

 margin of tlie shell and the hinge were of the types described above for ('. lopJiura. In other 

 respects it agreed witli ii. \V. MflJ, Kit's statement.
