10 B. W. Oates — On the Species of Thclyplioniis inJiabiting [No. 1, 



Structure, S . Clioliceres strong ; basal joint sliglitly punctured 

 and wrinlded towards the front ; second joint densely and coarsely 

 granulated, the anterior portion rounded, with five or more sharp distinct 

 teeth on the edge and two stronger ones on the lower surface ; third 

 joint thickly punctured all over and wrinkled towards the interior edge, 

 which is angular and furnished with one spine, another spine below ; 

 foiirth joint sparingly punctured all over and slightly granulated towards 

 the origin of the apophysis which is triangular (Fig. 1) and slightly 

 curved backwards, closely serrated on the outer edge and furnished with 

 a few blunt spines on the inner ; fifth joint large, broader than the 

 fourth, sparingly punctured all over, fixed finger triangular, short and 

 broad, finely serrated on the outer edge, the inner edge rough and 

 furnished with a few small spines ; movable finger slightly curved, the 

 upper edge sinuated, finely serrated and with a blunt tooth near the tip 

 (Fig. 5,), the lower edge simply curved and roughly serrated. 



Cephalothorax densely granulated with a sharp sinuated ridge 

 between the lateral and central eyes. 



First lower abdominal segment of huge size, tumid, divided longi- 

 tudinally by a groove and broadly i-ounded posteriorly (Fig. 3). 



Structure, 9 . The abdomen much larger and the cheliceres shorter 

 and slighter ; the apophysis of the fourth joint of the cheliceres is also 

 much broader at the base, but of about the same length, and conseqirently 

 much blunter ; the first abdominal lower segment is pointed posteriorly 

 and barely grooved (Fig. 4). The movable finger is also of a very 

 different shape and size (Fig. 6). 



An examination of the late Dr. Rtoliczka's types and of some other 

 specimens more recently acquired by the Indian Museum demonstrates 

 that his T. indicus is the male and T. beddomei the female of the same I 

 species. 



The number of teeth on the front edge of the second joint of tlie 

 cheliceres varies much in this species as may be seen from the following 

 onumeraticn of examples examined. 



c? . 7 teeth on right ; 5 on left with traces of 3 more. 



d'. 6 on right one being bifid ; 5 on left with trace of another. 



d' . 6 on right ; 5 on left. 

 . 6 on right ; 5 on left. 



9 . 7 teeth on each side (T. beddomei). 



the specimens I have examined came from Southern India and 

 Western Bengal, but no precise locality is attached to them. 



Mr. Butler identifies his T. sepiaris with this species (Ann. & Mag. 

 Nat. Hist. ser. 4, vol. xii, p. 116), but as he gives T. sepiaris from 

 Tonghoo Midi Ceylon, and allows T. beddomei to be a good distinct species,
