G. W. MlIller's and my figure; the proportion between its length and that of the second joint 

 of the first antenna is about 4:5. 



Upper lip: — The part between the combs on the postero-ventral edge of this lip 

 is rather deeply and narrowly notched; it is not quite as deep as in my fig. 15 of C. rotundata. 

 The paragnates are of about the same type as in C. symmetrica. 



Female: — 



Shell: — Length: According to G. W. Muller, 0,8—0,95 mm. The specimens 

 measured by me were 0,7 — 0,85 mm. long. Length : height about 1,4 : 1. S e e n f r o m t h e 

 side it has about the same shape as is described by G. \\. MIJLLER; cf. the accompanying

fig. 3. S e e n f r o m b e 1 o w it is of about the same type as in the male, but the anterior part is 

 scarcely perceptibly larger than the posterior part and the side contours are not curved in or 

 scarcely perceptibly so just behind the middle. The left unsyrametrical gland has its exit some- 

 what ventrally of the postero-dorsal corner of the shell; see the accompanying fig. 4. In other 

 respects it is like that of the male. 



First antenna: — The division into joints is rather weak. The first joint is, 

 as is the case in the male, somewhat shorter than the second. The boundary between the 

 original second and third joints is in most cases rather well developed. The bristle of the second 

 joint has .short hairs or is almost bare; it is somewliat shorter than this joint (fig. 7). E-bristle:
