" The five spines o£ the anfcero-lateral margin are all well developed, 

 bufc the three anterior are very slightly larger than the fourth and fifth. 



" The basal antennal joint is very distinctly granulated ; the max- 

 illipeds present nothing remarkable. 



" The chelipeds in the male are subequal, the merus or arm with 

 three spines on its anterior margin, of which the two nearest to the 

 distal extremity are largest ; wrist with a strong spine on its inner 

 margin and three small spinules on its oater surface, palm with three 

 or four spines disposed alternately in two series, on its upper surface, 

 and with three granulated ridges on its outer surface, between which 

 are other granules, as in Thalamita savigiiyi ; tlie fingers are somewhat 

 shorter than the palm, and irregularly denticulated on their inner 

 margins. 



" The ambulatory legs slender and slightly compressed ; the fifth 

 legs shaped much as in Thalamita admeta and Thalamita savignyi, with a 

 spine near the distal end of the inferior margin of the merus- joint, and 

 with the inferior margin of the penultimate joint armed with a very 

 distinct series of small spinules. 



Colour (in spirit) pinkish-brown ; pubescence whitish." 



The above is Miers' description, which I have copied, as I am not 

 perfectly sure of the identity of our specimen. It should be added that 

 the basal antenna-joint is " Goniosoma "-like, its extreme extent being 

 less than the major diameter of the orbit, and that the front is cut per- 

 fectly straight. 



In the Indian Museum is a single egg-laden female from ofE Ceylon 

 34 fms. The carapace is 5*5 millim. long and 9 millim. in extreme 

 breadth. 



63. Thalamita Woud-Masoni, n. sp. 



Carapace nearly three-fourths as long as broad, convex, crossed 

 transversely by ridges, which have the same disposition as in T. sima, 

 T. admeta, T. investigatoris, etc., and are all very distinct and straight. 



Front cut into 4 rather obscurely marked lobes (not including the 

 inner supra-orbital angles) of which the two middle ones are very broad 

 and the two lateral ones very narrow : the inner supra-orbital angles, 

 which are well arched, are broader than the lateral lobes of the front but 

 much narrower than the median lobes. 



A ntero- lateral borders nearly straight, cut into 5 sharp teeth, of 

 which the 4th is rudimentary arid is visible only when the carapace is 

 denuded of its close pile. 



Posterior border of dorsum of carapace straight but forming a 

 curve with the postero- lateral borders, its length is rather more than 

 two-fifths the greatest breadth of the carapace.
