species ; at the anterior end of the upper surface of the fourth 

 a deep and conspicuous pit-like excavation is present. 

 Fourth and fiftli segments much wider than the anterior ones, 

 the fifth being the widest. Keels almost quite as strong in 

 the male as in the female, but the terminal granule of 

 segments 2—4 is only slightly enlarged and is not so strong 

 as in the female [in T. pococki the caudal keels are distinctly 

 weaker in the male than in the female]. Median lateral keel 

 of second segment usually still discernible at the posterior end 

 of the segment. Median keels of ventral surface of second 

 segment approaching one another near the posterior end, and 

 sometimes touching one another, but never fused ; in the 

 third segment these keels are fused together posteriorly, so 

 as to form a single median keel, and in the fourth a median 

 keel similar to that of the fifth runs the entire length of the 

 segment, but a lateral keel is present on either side of it at 

 the anterior end ; similar lateral keels are sometimes present 

 also in the fifth. lutercarinal spaces finely but distinctly 

 granular. 



Hand of chela very much wider than the tibia, but its 

 width is less than the length of the hand-back; fingers lobed, 

 the movable one is about one and two-thirds the length of tl.e 

 hand-back. 



Fectinal teeth 13-16 in number. 



Movable finger of hand with fourteen rows of granules 

 (including the basal one). 



Colour varying from reddish brown to very dark brown ; 

 whitish specks, similar to those present in young examples of 

 T. camhridgii championi, Poc, are often present on the trunk, 

 but they are very faint or absent in the darker examples ; 

 last two segments of the tail (and the vesicle also) much 

 darker than the anterior segments ; the basal two-thirds 

 of the aculeus pale ; legs and chela reddish, they are 

 speckled in the paler examples but unicolorous in the darker 

 ones; fingers of the hand blackish except for the tips, which 

 are yellowish. 



$ . — Tail very different in shape to that of the male, for it 

 is not incrassate posteriorly, and the posterior segments are 

 not nearly so high; the impression on the dorsal surface of 

 the fourth segment is not nearly so deep nor is it so well 

 defined as in the male. 



Hand about as wide as the tibia and with much stronger 

 keels on its surface than in the male ; its movable finger is a 

 little more than twice the length of the hand-back, and shows 

 only a very slight tendency to lobation.
