in sliape, tapciing distally to a narrowly lOLiiided apex; the distal tvvo tliirds of 

 its niaigiii arnied witli aboiit eighteen long slcnder spiiies, iiiciuasing in ieiigtli 

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

 the telson ; a Single very sleniler median spinc at the apex between the terminal 

 spines of the margins; median set.T absent. 



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

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

 the otocyst ; outei", abont one and a half tiines as long as the telson. 



Length of an adnlt and mature male anti female, 10 mm. 



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

 The fii'st and sccond thoracic limbs aiul tlie moiith-parts, as well as the male 

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

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

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

„Ciirapace submembranaceous, covering whole pereion except the hindmost 

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

 anterior, or ccphalic, part of the carapacc is marked off by a distinct siilcus anil 

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

 to form a short, somewhat upturned rostrinn. The antero-lateral Corners evenly 

 ronnded. 



The eye-scales, or ocular plates, as compared with Ihose in the otlicr species 

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

 are of an almost qnadrate form, with a 

 sharp line running aiong the lateral side. 

 The Upper side with a short styliform 

 process visible froni above and froin the 

 medial side. The anterior-inferior inargin 

 is rounded off. 



The peduncular joints of the anten- 

 nulae very largc, short and thick, especially 

 the last one, which is as long as the tvvo 

 proximal ones, but broader. An oblique, 

 broad band of dark-brown pigment-spots 

 is on the upper side of the third Joint, pjg 235. Fi» 236.
