G. EuRTDiCE iNERMis, H. J. Hansen. (PI. 35. figs. 3 «-3 c.) 



Male and female, 

 1890. Eurydice inermis, H. J. Hansen, Cirolanidae, &c. p. 366, pi. v. 

 figs. 3-3/ (female). 



Process of clypeus very small, seen vertically from below 

 covering a minute portion of the area between the mandibular 

 palps. 



Auteunulae. — Male : The antennulse reach to the anterior 

 lateral angle of thorax. Peduncle much thickened, especially its 

 two proximal joints. Plagellum moderately robust at the base? 

 otherwise slender; first joint somewhat compressed, a little longer 

 than the combined length of the two distal joints of the peduncle 

 and conspicuously more than twice as long as that of the other 

 joints of flagellum, furnished with a good number of moderately 

 long sensory hairs ; second joint twice as long as the third ; fourth 

 joint terminates in some set?e, one of which is robust and even 

 somewhat longer than the whole flagellum. — Female : Rather 

 slender, especially flagellum which does not reach the front 

 lateral angle of thorax ; flagellum otherwise nearly as in the male, 

 but with rather few sensory hairs and the terminal setae short. 



Peduncle of antennae with the penultimate joint conspicuously 

 more than half as long as the terminal one. 



Epimera of all thoracic segments with their posterior angles 

 subsimilar, at most produced into exceedingly small processes. 



Seventh thoracic legs rather slender ; fourth joint somewhat 

 longer than broad and somewhat shorter than fifth ; both these 

 joints on the lower surface without spines and almost without 

 setae, those of the margins excepted. 



Last abdominal segment has on its upper surface a transverse 

 broad impressiou, often connected with vestiges of transverse 

 sublateral impressions. Posterior margin very short, less than 

 one-fourth as long as the breadth of the segment, slightly convex, 

 with about nine very distinct saw-teeth, the most lateral pair 

 a little longer than the others ; no marginal spines. 



Uropoda unusually small in both sexes ; endopod, when 

 directed parallel with the axis of the animal, far from reaching 

 to the posterior margin of a.bdomen. 



Length of an adult male 5-6 mm. ; of a female with marsupium 

 5"2 mm. 



Occurrence. — This species was established on an adult female 

 and two immature specimens from Cape Lizard, southern end of
