Mr. A. G. Butler on the Genus Thelyphonus. 205 



In our example the first tooth on the inner edge of the 

 second joint (first joint of Wood) is almost imperceptible ; so 

 that there seem at first sight to be only foui", instead of five 

 teeth.

18. Thelyphoynis lucanoides^ sp. n. PL XIII. fig. 6. 



Closely allied to T. seticauda, but considerably larger and 

 darker ; the cephalothorax comparatively longer and narrower, 

 with the fork of the median depression terminating also much 

 further from its inferior edge ; the abdomen more cylindrical 

 and with less distinct marginal ridge; the cheliceres more 

 distinctly punctured. 



Length 1 inch 1 line.

A broad, well-marked form, having six teeth on second 

 joint of cheliceres and a very depressed abdomen ; it has been 

 confounded with two, if not three, other species. 



20. Tlielyplionus sinensis, n. sp. PL XIII. fig. 7. 



Allied to T. caudatus, but larger and blacker ; cephalothorax 

 comparatively longer ; cheliceres duller and less rugose, second 

 joint with all the teeth considerably longer, the third being 

 most prominent. 



Length 1 inch 7 lines. 



Hah. Hongkong, from J. C. Bowring, Esq, B.M. 



Unquestionably a local form of T. caudatus, but sufficiently 

 different to require a distinctive name. 



21. Tlielyplionus rufus, n. sp. PL XIII. fig. 8. 



Allied to T. rufipes, but much larger and entirely of a 

 reddish -chestnut colour ; the cheliceres much more coarsely
