Exopods of all tlie thoracic linibs witli tlie oiiter distal corner of tlie basal 

 Joint sliglitly acuminate and tlie flagelliforni part composed of ten joiiits. 



Incubatory lamellce of tlie female, two pairs. 



Telson not quite so long as tlie last segnicnt of tlie pleoii and once and 

 two tliirds as long as broad at i(s bnse, wliere tlie niargins are soniev\liat 

 expaiidcd ; entirc and lanciforni in sliape, tapeiing distally to a narrowly rounded 

 Bpcx; distal two tliirds of its niargins arnictl witli abont twenty-four sliort spines, 

 increasing in lengtli towards tlie apex; median apical seta; absent. 



Uropods nioderately slender: inner, about one and a half times as long as 

 the telson, otocyst ratlier large, witli appareiitly iio spines on its inner niargin ; 

 outer, broken in botli speciniciis.

„Carapace covering all the thoracic segnients excei^t the last, which is fully 

 exposed; eveiily rounded in front and not produced info a rostral projcction; 

 antero-lateral corners rounded; emarginate beliind; cervical sulcus well niarked. 



Pleon longer tiiaii the carapace, first segnicnt sliglitly loiiger than the 

 second, which is subequal to the tliird, fourtli, aiid fifth; sixth segnient rather 

 long, two and a half times as long as the fifth. 



Eyes a little larger than in the last species, set dose together aiia rather 

 subquadrangular than pyriform in dorsal outline; the digitiform process on the 

 inner and U|:per face niore slender and a little longer than in either the type or 

 the last species; Visual elements imperfectiy developed, numerous; pigment pale 

 purplish piiik. 



Antennular peduncle in the female cxtending slightly niore than halfway up 

 the Scale, thiid Joint rather shorter and not wider than the first; in the male rela- 

 tively a little longer, with the tliird Joint sliglitly longer and niore robust than in 

 the female; male process well developed and hirsute. 



Antennal peduncle only sliglitly shorter than tlic antennular; tliird Joint the 

 longest and most robust. 



Antennal scale extending for rather less than half its lengtli beyond the 

 antennular peduncle; about tliree times as long as broad; outer niargin slightly 

 sinuate and terminating in a very strong spine which projects for its entire length 

 beyond the apex of the scale; outer distal corner of the basal Joint prolonged 

 iiito a long acute spine. 



Telson about three quarters of the length of the last segnient of the pleon 

 and sliglitly less than twice as long as broad at its base; entire and lanciforni
