feriiig from the principal form by having the tibia of the palps 

 somewhat more slender, and the galea not quite so deeply bran- 

 ched. — I suppose that the five young specimens belong to the 

 same species. 



AVhether the animal which Banks named Chelanops tristis, 

 is the same species is, however, more doubtful. 



5. — Chelifer scalbriculus E. Simon. 



U. S. A. California: Grant, 1 cf . 



The species belongs to the cancrokles type. The 8 anterior 

 tergites of the male have lateral keels and are strongly pro- 

 duced. 



The tarsus of the I. pair of legs has at the outer corner a pro- 

 jection. The claws of the I. pair of legs have no tooth, those of the 

 IL pair have an indistinct tooth, the III. an IV. pair have a di- 

 stinct one. — Balzan and TuUgren who have studied the species, 

 the former under the name of Ch. degeneralus, have probably, 

 none of them, had a male for examination; I therefore give here 

 the measurements of the male mentioned above. 



Length 2.58 mm. 



Abdomen: long. 1.86; lat. (between the keels) 1.03. Cephalo- 

 thorax: long. 0.72; lat. 0,72. Femur: long. 0.74; lat. 0.17. Tibia: 

 long. 0.57; lat. 23. Hand: long. 0.60; lat. 0.34. Fingers: long. 

 0.51 mm. 



Pseudogarypus nov. gen. 



Nathan Banks has described a North American species of 

 Pseudoscorpions under the name of Garypus bicornis. He him- 

 self is aware that the species perhaps does not belong to the ge- 

 nus Garypus, saying: « This species might, on account of the 

 structure of the cephalothorax and the absence of trochantins, 

 form a new genus ». — The last remark is, nevertheless, only 

 partly correct, as will be seen from the diagnosis below, but I 

 agree with Mr. Banks thas it will he necessary to form a new 

 genus which I propose to name Pseudogai-ypus. The diagnosis of 

 the genus may be put up thus:
