Diagn. Corpus carinatum, ssepe serratum. Femur pedum percei parium trium ultimorum angustum, 

 plus quam ter longius quam latius. Tibia pedum quinti paris post paullo producta; dac- 

 tylus levis. Pedes uri primi paris pedes secundi paris non superantes; pedunculus ramo in- 

 terno paidlo longior; ramus externus pedum secundi ac tertii parium dimidio interno paullulo 

 longior. Telson dimidio segmenti ultimi uri paullo brevius, pedunculo pedum uri ultimi 

 paris angustius, ac quintam partem longitudinis pedunculi ejusdem haud asquans. 



The body is carinated, and often serrated. The femur of the last three pairs of permopoda 

 is narrow, more than three times as long as broad. The lower hind corner of the tibia of 

 the fifth pair is somewhat produced; the dactylus is smooth. The first pair of uropoda do 

 not attain the apex of the second pair; the peduncle is a little longer than the inner 

 ramus; the outer ramus of the second and third pairs is a little more than half as long 

 as the inner. The telson is not fully half as long as the last coalesced ural segment; it 

 is narrower than, and scarcely a fifth part as long as, the peduncle of the last pair of 

 uropoda.
