936 CEUSTACEA. 



and transversely wrinkled, its free margin is bayed in the middle line, bnt not 

 greatly lamellar and projecting forwards over the epistomial region, as in Paratel- 

 plmsa sinensis, M.-Edw., and in P. spinigera. 



The inflected portion of the carapace is finely tnberculated anteriorly ; anterior 

 pleural lobe distinct and almost devoid of tubercles ; posterior pleural smooth, 

 thickly granulated where it bounds the anterior pleural. 



The anterior boundary of the epistoma is crenulated ; its posterior margin is 

 notched on each side of the middle line from which a long sharp process extends 

 downwards between the palpiform appendages of the external maxillipedes ; this 

 process does not correspond exactly with the triangular process of the epistoma in 

 other species of Telpliusa, but is the greatly developed median palatal ridge ; exter- 

 nally to each notch the posterior margin of the epistoma forms two distinct lobes 

 with granulated edges. The second joint of the external maxillipedes is punctate 

 and its external margin crenulated. The third joint is much broader than long, and 

 has its external and anterior angles well rounded oif and distinctly granular ; the 

 exopodite is crenulated on its internal margin. The abdomen of the male diifers 

 greatly from that of Paratelplmsa sjnnigera, having the form of an isosceles triangle. 



The chelipedes are greatly unequal in size, both in males and females, especially 

 in the former ; the meropodites have their ventral angles rounded off as in JParatel- 

 plmsa spinigera, their outer or posterior face rugose, their posterior angle also rugose 

 and armed with a sharp spine arising just proximally to the constriction near the 

 distal articular end ; carpopodites faintly rugose above, armed with a single exces- 

 sively long, stout spine ; penultimate joint absolutely tubercular above, externally 

 and internally all but smooth ; in the larger claw a considerable hiatus exists between 

 the deutated margin of the prolongation of this joint and that of the dactylopodite, 

 which in the smaller claw is throughou.t its length in complete contact with the 

 immovable arm of the pincers. 



The terminal joints of the ambulatory legs are extremely slender, acute, and 

 armed Avitli fine sharp spines.
