poda, but misunderstood the characteristic regarding the seventh pair, saying that this 

 pair are much shorter than the sixth pair, just as in Cyllopus. Axel Boeck was probably 

 misled by the British authors when he in 1875 took up the name Tauria as a synonym 

 to Metoecus, Kroeyer, rejecting the latter name as being preoccupied. In 1885 I restituted 

 the genus Tauria, Dana, within its old limits, as mentioned above, and claimed it as 

 a genus of its own, belonging to the family Hyperiidae. 



Tauria is probably closest allied to the genus Hysteria; as we know it from 

 Dana's description and drawing it is, however, readily distinguished from all the other 

 genera of the family by the narrow, not produced carpus of the second pair of perseopoda. 



The generic diagnosis, given by Dana 1. c. p. 988, runs: 



»Antenna3 four, short, approximate at base, superior rather stout. Feet not sub- 

 cheliform, nor subprehensile, seventh pair hardly abbreviated".

Dhig'il. Caput permagnum. Perceon breve, crassum. Epimera quarti paris margine producta et acuta. 

 Pedes percei priori et secundi parium bene pubescentes; carpus pedum priori paris latus, 

 non productus, metacarpum longitudine valde superans. Pedes parium quinque ultimorum 

 nudi, subasquales. Pedes uri longi; pedes primi paris apicem pedum ultimi paris fere 

 attingentes, pedes secundi paris breviores, apicem pedunculi pedum ultimi paris attingentes. 



The head is very large. The person is short and stout. The epimeral of the fourth pair is 

 produced below, and acute. The first two pairs of perwopoda are quite pubescent; the car- 

 pus of the first pair is broad, not produced, much longer than the metacarpus. The last 

 five pairs are naked, subequal in length. The uropoda are long; the first pair reach 

 very nearly to the apex of the last pair, the second pair reach only to the apex of the 

 peduncle of the last pair.
