ON SOME PSEUDOSCORPIONS FROM JAPAN. 15 



short sinuation at the base, the outer side a httle widened at 

 the base and the extremity, straight along the greater central 

 part. Tibia, as usual, calyciform. Hand with no stalk, the 

 outer side nearly straight or slightly convex, the inner side some- 

 what widened at a little distance from the base, and then nearly 

 straight, passing evenly into the fingers; the hand on the whole 

 is slender and nearly parallel-sided. Fingers of equal length, 

 seen from above slightly curved, much longer than the hand; 

 the fixed finger, throughout the whole length of the inner mar- 

 gin, has a row of strong, acutely triangular teeth, at a conside- 

 rable distance from each other; the moveable finger has only 

 some low teeth in the distal third part. 



Mandibles. The moveable finger is a little swollen exteri- 

 orly at the rounding, the inner margin being provided with 

 small teeth; the fixed finger has teeth along the proximal two 

 thirds of the inner margin, increasing in size distally. 



Legs with long, pointed hairs. The femora of the two po- 

 sterior pairs very broad. Claws simple. 



Length 1.33 mm.

This species has great affinity to Ch. Wlassicsi Daday, 

 from New Guinea, but the tooth in the front margin of the cé- 

 phalothorax in this species is much larger, and in the Japanese 

 species I have not been able to detect the crenulated claws of 

 the legs, nor the spht hairs of the coxa of the 2nd pair of legs, 

 peculiar to Daday's species.
