KITTONIA

The genus includes two species, K. nitida P. and K. robusta P. (fig. 211), 

 represented in the text, after one of my photographs, taken from a specimen 

 forwarded by Dr. Pantocsek. The two species are found in a fossil state at 

 Kusnetzk (Russia).

Fig. 212. Kittonia elaborata. 



Valve biddulphoid, elliptic, furnished with two processes, the apex 

 of each being enlarged and widened into a cup. 



This genus comprises three species, one of which (K. gigantea Grev.) is 

 ound in the deposit of Cambridge Estate, Barbadoes, while the other two 

 have been found in the deposit of Oamaru, New Zealand. I give in the text 

 (fig. 212), one of them, the most beautiful, K. elaborata, Grove and Sturt, drawn 

 from one of my photographs.
