22 G. O. Sars. 



pagation, as could be stated by 2 years continued inves- 

 tigation, is exclusively parthenogenetical, and this is prob- 

 ably also the case with all other species of the true genus 

 Cypris. 



Distribution. — India [Baird). 



2. Cypris ^ittata, G. O. Sars, n. sp. 



(PI. II, figs. 3, 3 a— c). 



Specific Characters. — Female. Shell shorter and 

 more tumid than in the preceding species, seen laterally, 

 oval in form, greatest height about equalling | of the length, 

 and occurring somewhat in front of the middle, dorsal 

 margin w^ell arched, ventral scarcely at all sinuated, both 

 extremities nearly equal and evenly rounded at the tip: — 

 seen dorsally, oblong oval, greatest width somewhat ex- 

 ceeding half the length, both extremities obtusely acuminate ; 

 — end-view remarkably oblique, left valve having its greatest 

 convexity at a much lower level than right, which latter, 

 as in the preceding species, is overlapped by the left along 

 the anterior extremity by a hyaline rim. Surface of shell 

 smooth and rather densely hairy at both extremities. Caudal 

 rami resembling in structure those in the preceeding species, 

 though somewhat more curved in their distal part. 



Colour. — ^ Shell semipellucid, with a slight greenish 

 tinge, and provided on each side with 4 successive dark 

 patches, forming as many interrupted transverse bands. 



Length of shell 086 ^m^ height 051 ^^\ width OoOi"™. 



Remarks. — This new species is at once distinguished 

 from the preceding one by the shorter and more tumid 

 shell, as also somewhat in colour. It is also rather inferior 

 in size, and moreover exhibits a remarkably oblique end-
