ENTOMOSTRACA COLLECTED IN NATAL. 177 



Proteocypris (?) globnloides sp. ii. PI. XXX, figs. 10-18. 



Shell seen laterally subovate, lieig-lit equal to two thirds of 

 the length (fig. 10), anterior extremity broadly rounded, 

 posterior somewhat narrower and more flattened, dorsal 

 margin well arched, highest in the middle, ventral slightly 

 sinuated. Seen dorsally the outline is very broadly oval, 

 almost circular, the width only slightly less than the length 

 (fig. 11), natatory setse of the posterior antennae not reaching 

 beyond the terminal claws (fig-. 12). Caudal rami simple, 

 bearing two apical seta9 (fig. 17). In other respects the 

 animal is essentially similar to P. reniformis. Shell quite 

 smooth, with a few marginal hairs, and showing by trans- 

 mitted light a rather coarsely reticulated structure. Colour, 

 brown. Length 0'4o nnn. 



Hab. — Richmond. 



This is a minute species, easily distinguished from the pre- 

 ceding by its very tumid outline, and on dissection, by the 

 shorter length of the swimming seta3, the character of the 

 caudal rami, and, in the male, by the more robust build of the 

 prehensile second niaxilhe. 



Genus Stenocypris G. 0. Sars. 



Stenocypris Ct. 0. Sars. ' On some Freshwater Ostracoda 

 and Copepoda raised from Dried Australian Mud' (Chris- 

 tiania, 1889). 



Shell much compressed and elongated, valves subequal 

 " free edges smooth, inner duplications vei*y large, especially 

 at the anterior part. Natatory seta3 of the posterior antennee 

 not reaching beyond the terminal claws. Palp of the first 

 pair of maxillae narrow, cylindrical, last joint small, masti- 

 catory lobes long and narrow. Caudal rami rather large, 

 more or less lamelliform, dorsal edges sometimes pectinate, 

 claws very unequal, both coarsely denticulate, seta of dorsal 

 edge absent or very small, the apical one i-ather elongate. 

 Propagation exclusively parthenogenetical."
