CEFSTACEA OP FRANZ-JOSEF LAND. 83 



Hebpetoctpbis arctic a, sp. n. (PL 4. figs. 2-6.) 

 Shell, seen from the side, subrenitbrm, highest in front of the 

 middle ; greatest height equal to fully half the length, extremities 

 broadly rounded ; dorsal margin moderately arched, ventral 

 slightly sinuated. Seen from above, ovate, tumid, greatest width 

 situated behind the middle and nearly equal to half the length : 

 posteriorly the sides converge in a broadly rounded curve and, 

 where they meet, form an obtuse angle ; they taper more gradu- 

 ally towards the anterior end, and the extremity there is slightly 

 acuminate. Colour bluish green, ornamented with darker streaks 

 and blotches. Length 1-9 mm. 



This Ostracod, which was moderately frequent in a freshwater 

 pond near Elmwood, Cape Elora, was collected July 30fch, 1897. 



Genus Candona, JBaird, 1845. 



Catsdona Haemswokthi, sp. n. (PI. 3. figs. 16, 17.) 



The shell, seen from the side, is somewhat subreniform ; the 

 dorsal margin is considerably elevated near the posterior end, 

 where the anterior and posterior slopes meet and form an obtuse 

 angle ; the greatest height is equal to rather more than half 

 the length ; the front slope curves gently downwards to the 

 evenly rounded anterior extremity ; the posterior end is sub- 

 truncate and forms a slight curve from the obtuse dorsal angle 

 -downwards and backwards to where it meets the ventral margin; 

 the ventral margin is distinctly incurved in front of the middle. 

 The shell, seen from above, is ovate ; the greatest width, which 

 is situated behind the middle, is equal to rather more than two- 

 fifths of the length; extremities slightly acuminate. Length 

 1 mm. 



I have named this quite distinct species after Mr. Harmsworth, 

 .of the Jackson-Harmsworth Expedition. 



Gandona harmsworthi has a distant resemblance to C. Candida, 

 var. claviformis, when viewed laterally, but the dorsal view is 

 dissimilar.
