but possibly the openings of lyriform organs or, perhaps, glands. While char- 

 acteristic of all the species they vary greatly in size, number and position 

 according to the species. They are very probably variable within certain limits 

 in the species also, at least T would suspect so judging from studies of Chelifer 

 scabriculus and C. fiiscipcs. 



The structures which 1 have referred to under the term "cribriform 

 plates" are small chitinized plates which are apparently perforated with numerous 

 pores. They occur near the genital slit of the females of various species in the 

 family Cheliferidae and vary greatly in size, shape and degree of chitinization. 

 I have found them most prominent in Chelifer scabriculus where they are almost 

 perfectly round and rather close together. Whether they occur in other families 

 I cannot say as I have not seen enough material to judge.

Pcdipalps — (Text fig. C). Palpi have almost same proportions as in 

 G. giganteus, but the inner margin of the hand is not so swollen, the inner 

 margin of the tibia is straight as is also the inner margin of the femur. 



CheUcerae — (Text fig. D). The spinnerets are long conical and as in 

 G. giganteus apparently unbranched, the serrula has about twenty-five teeth, the 

 fixed finger is very strongly curved, and the fixed finger serrula is very pro- 

 minent, having about twelve or thirteen teeth. 



Cephalothorax and legs — ^(Text fig. A). Cephalothorax sub-triangular 

 with anterior border emarginate. Legs as in G. giganteus all composed of seven 

 segments. In this species the tarsal bristles are arranged in regular rows. The 

 change from sparsely scattered fine hairs to these tarsal setae takes place at 

 the metatarsus, unlike G. giganteus where the transition is at the tibia. 



Abdomen — Much the same shape as in G. giganteus except that all the 

 ventral scutae are slightly more chitinized. The cribriform plates (Fig. B) 

 are oval in shape, with about twenty-three pores and no stoma. 



Material. An adult female from the type locaHty; Santa Clara County, 

 California. 



Remarks. In several places I have noticed descriptions of species in this 

 genus where the fact is mentioned that the second trochanter is present in the 

 posterior pair of legs, inferring that they were missing in the two anterior pair. 

 I think this is a mistake as in both these species the number of segments is the 

 same in all the legs. 



Other North American Species. 

 Two other species of this genus are described from North America. 

 These are Garypus floridensis and G. granulatus, both of which were described 

 by Dr. Nathan Banks. The four North American species may be separated by 

 the following key, which is based in part upon the literature. 

 1. Anterior margin of cephalothorax emarginate, fingers as long or longer 



than hand, length 4 mm. or greater 2 



Anterior margin of the cephalothorax not emarginate, fingers shorter than
