vol. iii. p. 174, pi. 10. fig. 1. 
E. V. Martens has reviewed this paper, and suggests that Oeorissa is iden- 
tical with Hydrocena, the diflerences in the position of the eyes and in the 
lines of the operculum being rather slight, and perhaps due to the different 
modes of observation ; besides, Hydrocena is in reality not a marine form, but 
lives in damp places of mountainous regions, just as Georissa. Mai. Blatt.
