 interiör one. The exteriör ramus of the last pair of uropoda 

 longer than half of the coalesced interiör one. The first and third 

 pairs are smooth, the second serrated at the inner margin. 

 The hinder corners of the pleonal segments are feebly rounded.

Tauria. Dana. 



The genus Tauria, founded 1853 ^) by Dana for a Hyperid 

 with the second pair of pereiopoda slender and not at all 

 cheliform, was united by Spence Bate -) with the genus Hy- 

 peria, Latreille. On account of the very obscure and somewhat 

 erroueous description given by Spence Bate, the genus has 

 been quite confounded, and not only låter authors, but Spence 

 Bate himself ^) has been deceived into transferring Hyperids 

 with totally opposite characters to Dana's genus. The generic 

 name Tauria was taken up again by A. BoECK 1872 for Hy- 

 perids belonging to the genus Metoecus of Kkoeyer (1838), 

 which generic name BoECK was obliged to reject, as in 1833 

 it had already been given to an insect. How far he was from 

 comprehending the description of Dana will be clearly seen 

 on comparing the description of Dana and the principal 

 characters quoted by Boeck.
