" THETIS " SCIENTIFIC RESULTS. 



PAGURAPSEUDES SPINIPES, sp. nov. 



(Figs. IQa-h.) 



Stations 13, 35, 37, 38, 57. 



Adult female. Body slightly tapering, upper surface without 

 well defined sculpture. Cephalon as long as broad, sides a little 



sloping, narrowed anteriorly, with 

 a faint groove, which extends to 

 the point of articulation with the 

 succeeding segment. 



Upper surface with a pair of 

 very shallow submedian depres- 

 sions and a low, broad median 

 elevation ; the latter commences 

 on the rostrum and is continued 

 beyond the sutural line ; the 

 depressions mark the inner limits 

 of the suture and cease opposite 

 to, but at a short distance from, 

 a pair of shallow pits, situated 

 anterior to the straight posterior 

 border. 



Rostrum wide, depressed, trun- 

 cated and minutely spinulose. 



Ocular lobes sharply defined, 

 outlines when viewed from above 

 triangular, with an inner ridge- 

 like process, which extends over 

 the base of the first antenna to 

 the external base of the rostrum. 

 Anterior and posterior regions of body. gyes indistinct, with several 

 Fig. 16«. dark pigment spots. 



Second (first free) segment about half the length of the third. 

 Anterior margin straight, sides slightly convex, marked superiorly 

 with a narrow groove, bounded by a ridge which gradually 

 increases in width posteriorly ; hinder border interrupted by a 

 pair of submedian incisions. 



Third segment with the anterior border arcuate, exhibiting six 

 indistinct depressions, and laterally spinulose; sides and posterior 

 Ijorder straight, the latter with a pair of widely separated notches. 



Fourth segment similar to the third, but longer. 



Fifth segment nearly equal in length to the second and third 

 combined.
