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

 Joint slightly acuminate and the flagelliforni part composed of ten joints. 



Incubatory lamellas of tlie female, two pairs. 



Telson not quite so long as the last segment of the plcon and once and 

 two thirds as long as broad at its base, wliere the niargins are somevvhat 

 cxpanded; entire and lanciform in shape, tapering distally to a narrowly rounded 

 Bpex; distal two thirds of its margins armed with about twenty-four sliort spincs, 

 incrcasing in length towards the apex; median apical setcC absent. 



Uropods nioderately siendef: iinicr, about one and a half times as long as 

 the telson, otocyst rather large, with apparently no spines on its inner niargin; 

 outer, broken in both specimens. 



Length of both specimens (immature females) 1 1 nun." (I. c. mit einer 

 kleinen Änderung.) 



Verbreitung: Bisher nur aus den irischen Gewässern (750—800 F.) bekannt.

„Carapace covering all the thoracic segments except the last, which is fully 

 exposed; evenly rounded in front and not produced into a rostral projection; 

 antero-lateral corners rounded; emarginate behind; cervical sulcus well marked. 



Pleon longer than the carapace, first segment slightly longer than the 

 second, which is subequal to the third, fourth, and fifth; sixth segment rather 

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



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

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

 inner and upper face more slender and a little longer than in either the type or 

 the last species; Visual Clements imperfectly developed, numerous; pigment pale 

 purplish pink. 



Antennular peduncle in the female extending slightly more than haifway up 

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

 tively a little longer, with the third Joint slightly longer and more robust than in 

 the female; male process well developed and hirsute. 



Antennal peduncle only slightly shorter than the antennular; third Joint the 

 longest and most robust. 



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

 antennular peduncle; about three times as long as broad; outer margin 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 

 into a long acute spine. 



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

 and slightly less than twice as long as broad at its base; entire and lanciform
