studies on marine Ostracods 237 



Penis: — This is of the fundamental type for this sub-family. For details see the 

 accompanying figure 20. There seem to be no glands on the ventral lobe. 



F u r c a: — Very like that of the female; the two or three distal claws are, however, 

 somewhat more curved. 



The rod-shaped organ and the upper lip agree with these organs in the 

 females. 



The lateral eyes are slightly larger than those of the females. 



The dorsal side of the back of the body has rather strong transverse 

 folds or ridges. 



Habitat: — South Georgia:

C. (Doloria) pectinata n. sp. 



Descriftion: — Female: — 



Shell: — Length, 2,45 — 2,8 mm. It agrees completely with the shell of C. (D.) 

 levis. The peculiar formations (pores?) of the list inside the posterior border of the 

 shell are, on the average, somewhat more numerous? 



First antenna: — This agrees very closely with that of the preceding species; 

 a slight, but apparently constant, difference is, however, to be noted with regard to the sensory 

 bristle of the fifth joint. Of the ten long proximal sensory filaments that distinguish this bristle 

 of the preceding species, the distal one is in this species displaced rather much distally and is, 

 in addition, somewhat shortened and narrowed; it thus constitutes a sort of transitional form to 

 the more distally situated filaments, the sharp division into long, somewhat thicker proximal sensory 

 filaments and short, narrow, distal ones being thus less marked in this species. On one specimen 

 two (normally only one) subequal anterior distal bristles were observed on the fourth joint on 

 the antenna of one side. 



Second antenna: — Protopodite: The medial-distal bristle is rather long, 

 about twice as long as the three shorter of the four proximal bristles of the first endopodite
