areas, especially on llio upper surface. There is a good deal to be said in favour of 

 Miers's view, that it is probably only a variety of T. Admete, to which species it was 

 originally referred by Audouin ; the amount of granulation certainly varies considerably 

 in a series of specimens. 



The largest male is 12-5 mm. long and T.) mm. broad, and the largest female is nearly 

 the same size ; but some females with ova are of much smaller size, a disparity which 

 has been noted by "De Man.

I refer these specimens with some hesitation to T. sima, and possibly they belong to 

 a distinct and undescribed species. The first three antero-lateral teeth are very broad 

 basally, and merely separated by narrow fissures, with their apices subacute, whereas in 

 the typical T. sima, as figured by De Haan, these teeth are more prominent and acute, 

 with wider intervening fissures. The carapace is finely granulated and the elevated 

 lines rather poorly marked ; the front is regularly arcuate, wdth the median notcli 

 scarcely represented. The outer surface of the hand is almost smooth. In T. Chaptali, 

 Aud., which is recorded by Miers from Ceylon ('Alert' Crust, p. 231), and in which the 

 antero-lateral teeth are also obtuse, the last tooth, unlike what is seen in ovtr specimens 

 and in the typical form, is slightly smaller than the preceding tooth. 



The larger specimen is 10 mm. long and 14-5 mm. broad.
