Shell: — Seen from inside (see fig. XLTIl): Medial bristles: The rostriim has rather 

 .sparse, in most cases bifurcated, bristles (of about the same type as is rejjroduced for C. (Dolorin) 

 levis, p. 228, fig. 2). Some of these bristles are arranged in a sparse row running obliquely upwards 

 and forwards; sometimes this row is not distinct, in some cases, according to G. W. Muller's 

 statement, all these bristles are scattered. The arrangement and number of these bristles 

 not onlv varv fi'om one specimen to another but are also different on the two valves. 

 Along the posterior edge of the rostrum there are also ratlier sparse bristles; at least some of 

 them are bifurcated. The two bristles near the inner edge of the rostral incisur are about as 

 large as the rostral bristles and seem to be furnished with fine, short hairs situated 

 close together. Apart from these bristles there is often only a single short bristle inside the 

 incisur near the joininu line Along the anterior part of the list hcliind the incisur to about 

 a fourth or a third of the length of the shell there is a moderate number of bristles, mostly 

 bifurcated ; farthei- back the\' are j:)ractically entirely absent, though a few may sometimes be foimd. 

 Inside the posterior margin of the shell the list is (if the tvpe describ(>d for (\ fV.) norvrgica 

 (eontrarv to ({. \V. IVIT'LU^li's statement). Between the list and the margin of the shell there 

 are in most eases no bristles. The selvage is very wide along the posterior margin of the incisur, 

 ijuite lilliiiii the hitter (cdntnirx- tn (J. W . Ml'I.I.KU's drawing), contiinies along the whole of the 

 ventral margin of tJie shell, extending here ,-i little outside of it. < )n the anterioi' side of the 

 r'ostrurn it also extends i)e\-oii(l the edn'e of the shi'll. but. on the othei hnnd. it is ver\' nari'ow
