932 CRUSTACEA. 



crenulated. Front broad, short, very little deflexed, terminated by a smooth margin. 

 The chelipedes are sub-equal ; the two inferior edges of their meropodites are armed 

 with tubercles, their inferior planes bear at their distal extremity and nearer the 

 inner than the outer of the two edges a single spinule, wloich is also to be remarked 

 in many other species ; the third or upper angle is rugose ; the succeeding joint is 

 greatly thickened at its distal end, and is superiorly coarsely wrinkled and concave ; 

 its inner margin is armed with a stout sharp spine, beneath which is a smaller one ; 

 the proximal half of the penultimate joint is convex and coarsely granulated exter- 

 nally, internally convex and smooth, except towards the inferior border, where two 

 or three rows of small, widely-separated tubercles are to be seen ; its upper surface 

 is ornamented by three rows of large tubercles ; its distal prolongation is deeply 

 canaliculate and its inner toothed edge is in contact throughout its length with the 

 dactylopodite, which is likewise canaliculate externally and compressed, so that its 

 upper border presents a saw-like edge, being ornamented with tubercles decreasing 

 gradually in size and sharpness from the base towards the tip. 

 The ambulatory legs are hairy, as in Telplmsa hisfida.

Carapace considerably broader than long, very sparingly hksute, areolation 

 similar to that of the preceding species ; anterior branchial region covered with 

 irregular tubercles, which gradually pass backwards into the rugations that tliickly 

 mark the postero-lateral margin, the inflected portion of the carapace, and a portion 

 of the posterior pleural lobe ; epi-gastric lobes separated from one another and from 

 the proto-gastrics, post-frontal crest curved forwards in the middle ; epibranchial 

 teeth well marked and pass backwards on each side as regularly denticulated crests, 

 the denticulations gradually decreasing in size backwards ; anterior pleural lobes 

 covered with inosculating fovea;, separated from the peristomial portions of the 

 posterior by a tuberculated hne w^hich loses its beaded character as it passes upwards 

 to the epibranchial tooth ; front broad, especially at the base, tuberculated ; its free 

 margin is sinuous, w^ell rounded laterally and coarsely crenated ; orbital borders also 

 crenated and rising externally into a salient, forwardly-directed tooth. The median 

 triangular process of posterior border of the epistoma is extremely salient, coarsely 

 crenate, and notched on each side; externally to the notches, this posterior border is 

 simUariy crenate up to the point at which it begins to form the anterior boundaries 

 of the exbalant orifices of the branchial chambers. Chelipedes sub-equal ; meropo- 

 dites with their three angles sharply tubercular, their posterior faces rugose and their
