the round joined part ventrally-proximally on the rostrum which is reproduced in the figiu-e 

 just mentioned. At the postero-dorsal corner of the shell there is a rather weakly developed 

 hinge-socket and hinge-tooth, of about the same types as in pi. II, fig. 1 (of C. magna, $),

First antenna: — The b-, d- and e-bristles are in most cases subequal, about 

 a quarter or a fifth longer than the joints of this antenna. The e-bristle had the following

armature in the specimens investigated by me (cf. for other details pp. 702 — 706 below): Somewhat 

 distally of the middle this bristle has two rows of proximally pointing spines along about 

 a quarter of its length. The distal spines in each of these rows are situated close together; 

 these sjaines are situated in pairs in the two rows. From the eighth or the tenth pair, counting 

 distally-proximally, the two rows approach each other and the spines push alternately in between 

 each other, so that a single, though not a quite straight, row is formed; at tlie same time the 

 distance between the spines increases, some of these being often even rather sparsely situated 

 (about the same as in pi. «. fig. 5. (!. \V. Mi'LLKH, 1894). Tii protih' ] saw about 20—25 spines
