in shape, tapering distally to a narrowly rounded apex; the distal two thirds of 

 its margin armed with about eighteen long slender spines, increasing in length 

 towards the apex; the terminal spines about one seventh of the total length of 

 the telson ; a Single very slender median spine at the apex between the terminal 

 spines of the margins; median setae absent. 



Uropods slender: inner, only a little longer than the telson plus the terminal 

 spines and with four long spines on its ventral inner margin in the region of 

 the otocyst ; outer, about one and a half times as long as the telson. 



Length of an adult and mature male and female, 10 mm. 



The third to the eighth thoracic limbs are broken off in both specimens. 

 The first and second thoracic limbs and the mouth-parts, as well as the male 

 pleopods, are in substantial agreement with the same parts in both the type and 

 the foregoing species, except that the last Joint of the mandibular palp is shorter 

 and somewhat more robust." (1. c.)

„Carapace submembranaceous, covering whole pereion except the hindmost 

 Segment. Sixth segment of pleon as long as the three preceding ones. The 

 anterior, or cephalic, part of the carapace is marked off by a distinct sulcus and 

 arched above. The frontal margin ends in an angle, which, seen en profil, seems 

 to form a short, somewhat upturned rostrum. The antero-lateral corners evenly 

 rounded. 



The eye-scales, or ocular plates, as compared with those in the other species 

 of the genus, rather small, not contiguous, with a free space between them. They 

 are of an almost quadrate form, with a 

 Sharp line running along the lateral side. 

 The Upper side with a short styliform 

 process visible from above and from the 

 medial side. The anterior-inferior margin 

 is rounded off. 



The peduncular joints of the anten- 

 nulae very large, short and thick, especially 

 the last one, which is as long as the two 

 proximal ones, but broader. An oblique, 

 broad band of dark-brown pigment-spots 

 is on the upper side of the third Joint, 

 which gives it a somewhat stränge appea-
