 minus prominens, intra utrinque levius excavatum, pars su- 

 perior recliva brevior, margo superior in medio integer. 



Trunci segmentum primum margine laterali minus 

 crasso, ad longitudinem paulo profunde sulcato, post leviter 

 fisso: lacinia interior exteriore vix longior sed crassior. 

 Supra sulcus lateralis satis profundus. Epimera segmenti se- 

 cundi ante crassiora. Margo posterior segmentorum priorum 

 subtransversus, utrinque levissime aut vix sinuatus. 



Cauda: Epimera segmentorum 3—4 — 5 oblique tetra- 

 gona; epimera segmenti 5ti convergentia. 



Exopodita omnium (?) pleopodum trachea instructa. 



Telsum multo latius quam longius, epimera segmenti 

 prsecedentis paulum superans: pars apicalis brevis, subrect- 

 angula. 



Uropodes telso vix breviores; scapus latere interiore 

 oblique curvato. P]xopoditum minutissimum, apicem scapi 

 non attingens; endopodituni telso vix brevius. 



Unicolor, e griseo brunneus.
