Deriv. ”Tats a greek name. 
Diagn. Corpus depressum, elongatum. 
Caput rotundatum, non rostratum. 
Oculi parvi, ocellis perpaucis compositi. é 
Antenne primi paris breves, articulis paucis composite. 
Antenne secundi paris dimidium longitudinis corporis superantes, 
flagello multi-articulato. 
Mandibule palpum tri-articulatum gerentes. 
Latera segmentorum pereii non vel paulo producta, bases pedum 
non tegentia. i 
Pedes pereii subequales, dactyli pedunculati, tri-unguiculati.

The body is depressed, elongate. 
The head is tounded, not rostrate. 
The eyes are small, cosisting of very few ocelli. 
The first pair of antenne are few-jointed. 
The second pair of antenne are longer than half the body, 
with multi-articulate flagellum. 
'The mandibles are provided with a three-jointed palp. 
The lateral margins of the pereional segments are scar- 
cely produced, not covering the bases of the legs. 
The pereiopoda are subequal, walking legs; the datcyli 
are pedunculated, tri-unguiculate. 
The uropoda consist, of thick, cylindrical peduncles, and 
two elongate, laminate rami. 
This new genus is easily to be distinguished from the 
other genera of the family by the tri-unguiculate dactyli of 
the pereiopoda. The other characteristics show that it ought to 
be ranged between Zanira and Ira: resembling the first in the 
elongated uropoda, and the latter in the few-jointed flagellum 
of he first pair of antenne, and in the not subeheliform first 
pair of pereiopoda.
