;< ii ,> 11; _ Lengtli : According to C. Clai.s 1,5—1,6 mm. According to G. W. MULI.ER 



1/^5 1,8 mm. According to G. H. Fo\M.ER 1,4 — 1,7 mm. The female investigated by me 



was 1,6 mm. long. The shape of the shell was as described by G. W. Mi'LLER. The surface of 

 the shell was liare. The selvage was as in C. lophurn. The glands along the posterior margin 

 of the shell and the hinge were the same as in ('. lophura. In other respects it agreed witii 

 (!. W. Mi'LLER's account. 



The first a n t e n n a was similar to that of ('. parvidentata, but the distal joints 

 on the specimen investigated by me were bare. In additinn this specimen had no small yellowish- 

 hiown corpuscles in the first and second joints. 



Second an t e ii n a: — Similar to that of ('. parvidentata, but the armature on the 

 a-bristle was almost as powerful as that on the b-bristle. There was no c- or d-bristle. 



M a n d i b 1 e : — Tlie p r o t o p o d i t e and the e p i p o dial a p p e n d a g e are 

 similar to those of C. lophura. The e n d o p o d i t e is perhaps somewhat more elongated 

 than in the species just mentioned. Its first joint has only two bristles on the posterior side; 

 l)c)th these bristles have short hairs; one of them corresponds in position and size to the lateral 

 one, the other to one of the three medial ones, of the corresponding bristles in C. lophura. It 

 is to be noted that in pi. VI, fig. 7, C. Claus, 1891 a, there are three bristles at the corre- 

 sponding place, one long one and two short ones. 



The m a X i 1 1 a, the f i f t h and sixth 1 i m b s, the f u r c a and t h e i- o d - 

 s h a p e d o r g a n are similar to those of C. parvidentata. 



Upper lip: — The part between the combs is of about the same type as in my fig. 4 

 of ('. Belgicae. The par a g n a t e s are similar to those of C. symmetrica. 



A;//, r„) ,/'">■• Remarks: — Besides the places given in the above list of synonyms C. hyalophyllum is 



mentioned in the following places: G. S. BRADY. 1902 a, p. 199 (= the same author. 1903, 

 pp. 337, 338, 339 and A. M. NORMAN, 1905, p. 155) and G. H. Fowler, 1903, p. 121. These 

 statements are not accompanied by any verificatory information or figiires. On account of 

 the great difficulty in determining with certainty the species of this group it did not seem to 

 me proper to include these statements in the list given above. 



('. hyalophyllum, Gil. Jihay, 1906, p. 20 is certainly not identical with ('. hyalophyllum 

 G. Gl.ALS. It is perhaps identical with the former author's C. matjua; cf. p. 692 al)ove. 



With regard to C. hyalophyllum, G. H. FoWLER, 1909 I refer to what is written on p. 565 

 above. I was unable to discover in the specimen investigated by me any lateral glands witli 

 exits such as are shown in this writer's pi. XX, fig. 97.
