Mr. R. T. Pocock on some new or 



liltherto established by the combination of the following 

 characters : — (1) The third segment of the tarsus of the first 

 leg is twice as long as wide and subequal to the second ; 

 (2) the second, third, and fourth legs are furnished with a 

 tibial spur ; (3) there are five spines on the upperside of the 

 trochanter of the chela. Judged by these features, T. Wayi 

 ranges itself alongside of T. manillanus under section 25 of 

 the table given by Kraepelin (Das Tierr., Scorp. &c. p. 216), 

 but certainly differs from that species in having the sixth, 

 seventh, and eighth tarsal segments of the first leg modified, 

 the ommatoids large, and the genital operculum angularly 

 emarginate in the middle of its posterior border.

A specimen of what is very likely the hitherto unknown

 the British Museum by Prof. d'Arcy Thompson, C.B. The 

 specimen was collected in Yokohama.
