The right chelipede only is present : on the proximal half of the 

 anterior border of the merus are three or four minute, but sharp, 

 teeth as in P. nitidus, but none on the posterior border, \\ hich, 

 however, terminates in a very blunt low tooth a little before the 

 carpal articulation. The hairy growth on the proximal portion of 

 the hand is continued over the joint on to the external surface of 

 the carpus.

Besides the granular teeth on its anterior margin, the meri of

1 I have since found that this form should be referred to Dana's Pteudozius 

 dispar. with which P. nitidus is synonymous {vide Caiman, Trans. Linn. Soe. 

 ser. 2, Zool. Tiii. p. 14, 1900).
