surmounted by an evenly denticulated crest ; posterolateral margin 

 covered with oblique wrinkles which pass forwards and downwards 

 on to the inflected portion of the carapace ; posterior pleural lobe, 

 where it is bounded by the anterior pleural, rugose ; the latter is 

 limited off by a line of regular bead-like tubercles ; post-frontal crest 

 continuous to the epibranchial teeth from the meso-gastric furrow, 

 curving forwards mesially and at each end ; post-frontal furrow 

 Smooth behind the eyes ; front narrow, denexed, raised into a 

 bilaterally symmetrical pair of eminences. Chelipedes subequal in 

 the only specimen* (a female) in my possession ; the meropodites 

 are tuberculately rugose on their posterior surfaces and their 

 ventral angles are beset with long tubercles ; the carpopodites are 

 rugose above and their inner margin is armed with a very sharp long 

 spine from the sides of which spring 2 or 3 minute cusps ; beneath 

 the larger spine a smaller one is to be seen. The penultimate joint 

 is externally rough, internally near the inferior margin tuberculated 

 and above presents a few spiniform tubercles ; the dactylopodite 

 which is in contact with the other arm of the pincers throughout 

 its length line has a few spinules above near its proximal end. 



Length, 32 mm. 



Breadth, 41 mm. 



The posterior pair of ambulatory legs has not been preserved, 

 but from those that remain, it will be seen that the penultimate 

 joints resemble slightly those of Telphusa Austeniana, and of 

 T. Stoliczkana. I have named this species after Mr. S. E. Peal, to 

 whom the Indian Museum is indebted for many novelties in the 

 various groups of Arthropoda.

 The carapace is much broader than long, smooth, punctate mesi- 

 ally and posteriorly ; the anterior branchial lobe is not greatly 

 swollen above, is covered anteriorly with coarse granulations ; 

 epigastric lobes granulated, separated behind and laterally from the 

 granulated proto-gastric and from one another by the meso-gastric
