Cytherura mucronata, T. Scott. 



(PI. LXIIL, figs. 18, 19.) 



1890. Cytherura mucronata, . . Scott, T., " Additions to the Fauna of the 



Fii-th of Forth," Eighth Ann. Rep. Fishery- 

 Board for Scotland, p. 323, pi. xii., figs. 3—5. 



" Shell, seen from the side, elongate, narrow ; height about equal at both ends, 

 length two and a-half times the height ; dorsal margin nearly straight, ventral 

 margin slightly and evenly concave, posterior end much produced, and wedge- 

 shaped, forming a ' beak,' which is situated below the middle ; anterior margin 

 broadly rounded, somewhat produced in the middle. Seen from above, oval, with 

 the ends acuminate ; the margin at each end, especially at the anterior, is 

 produced so as to form a distinct ' mucro.' The surface is marked with indistinct 

 raised lines, which are somewhat irregularly distributed ; the breadth is equal to 

 the height. Length, -33 mm." 



Habitat. — Off St. Monace ; not very rare. 



We figure one of Mr. Scott's specimens, but believe that it must be referred to 

 the young of Cytherura producta, Brady.
