tooth on each side. The mesogastric furrow is shallow and somewhat hroad. The cervi- 

 cal groove is well denned, and passes as far as the postfrontal ridge, slightly internal to 

 the epibranchial tooth, but it does not interrupt the ridge; it is most strongly marked 

 between the anterior branchial and the protogastric lobes. The branchial regions carry 

 many transverse finely crennlated lines, which posteriorly curve round to the under 

 surface of the carapace. The epibranchial tooth is continued into a finely crenulated 

 carina, which extends along the anterior half of the anterior branchial region, and finallv 

 curves inwards on the carapace. The border between the epibranchial tooth and the 

 external orbital angle is sinuous and finely crenulated. The frontal margin is slightly 

 concave towards the middle, and both it and the orbital margin are obscurelv crenu- 

 lated. 



The chelipedes are unequal in both sexes, either right or left being larger ; the merus 

 and carpus have short raised lines externally which almost impart a squamose appearance ; 

 the carpal spine is well developed and acute, with a small obtuse tooth in front of its 

 base ; the hand is smooth externally, but slightly rugose on the inferior proximal 

 margin ; the fingers are strongly toothed, and in adults there is usually a single specially 

 enlarged tooth on the immobile finger of the larger chelipede. The ischial line of the 

 external maxillipedes is placed considerably nearer the inner or median margin of the 

 joint. The ambulatory legs are carinated along the anterior margin, and the carpal 

 joints of the first three pairs have in addition a carina on both the anterior and the 

 posterior surfaces. The male abdomen is slightly constricted towards the middle, 

 becoming wider towards the distal end of the penultimate segment. 



The carapace of an adult female is 41 mm. long, and 52 mm. in greatest width.

Pundaloya, Ceylon, a male (E. E. Green); "Madras," a single specimen (Brit. Mm.). 

 The latter specimen probably came from one of the South Indian hill-ranges, and not 

 from the neighbourhood of Madras. 



I refer these with some hesitation to this insufficiently described species. It is, as 

 Kingsley remarks, closely allied to T. Icecis, Wood-Mason, and the two may afterwards 

 prove to be identical. The carapace is smooth and moderately convex, with no post- 

 frontal ridge, and merely the rudiment of an epibranchial tooth. A faint depression 

 between each anterior branchial and protogastric lobe indicates the cervical groove, and 

 there is a shallow indication of the mesogastric furrow. The median portion of the 

 frontal margin is inflected. The ischial line of the external maxillipedes is placed nearly 

 in the centre of the joint. The ambulatory legs are very slender, and the three terminal 

 joints are provided with many short setose hairs. In the above specimens the chelipedes 

 are similar to those of T. Icevis, as described and figured by Wood-Mason. 



The Ceylon example is 12 mm. long, and 15*5 mm. broad. 



In the British Museum there is a series of a closely allied and perhaps identical species 

 from North India, which I refer to T. Icevis, as the specimens agree well with Wood-
