Notodromas fuscatus, n. sp. (Plate X. figs. 4-6.) 



Shell, seen laterally, subtriangular, height equal to three fourths 

 of the length, extremities very broadly rounded, the anterior some- 

 what the narrower of the two, dorsal margin excessively arched, 

 highest a little behind the middle ; ventral nearly straight ; seen from 

 above, the outline is ovate, scarcely twice as long as broad, tapered 

 and acuminate in front, rounded oflf behind. Surface of the valves 

 somewhat rough and furfuraceous, colour brownish, with darker 

 cloudings. The ventral aspect of the shell is ribbed almost exactly 

 as in N. monachus ; the " ocular " tubercle is large and distinct ; by 

 transmitted light the shell is seen to have a polygonal reticulated 

 structure, and the reticulations are visible also by reflected light on 

 the anterior portion of the valves. 



Hab. At Condong, with the foregoing species. 



This is very much less tumid aud less angular in outline than

The shell figured in Plate VIIL figs. 10, 11, occurred in the same
