 Locality. — Berkeley (author, April, I9II). 



Gosiphilus bakeri sp. nov. 



Cephalic plate widest caudad, being a little narrowed cephalad to anterior 

 corners, the border in front of corners triangular; wider than long (in ratio 

 15:13). Basal plate short, a little narrowed caudad, not quite as wide as the 

 cephalic, about two and eight-tenths times wider than long. Prehensorial feet 

 completely covered by cephalic and basal plates ; claws weak, not strongly curved, 

 not touching distally, short of attaining front margin of head. Prosternum very 

 much wider than long (28:15); chitinous lines strongly developed and complete 

 as usual. Spiracles all circular. Ventral pores in a circular or subcircular area 

 just caudad of center of sternites. Last ventral plate wide, sides straight, 

 moderately converging caudad ; caudal margin truncate. Coxopleural pits two 

 on each side, the more caudal one partly covered and the anterior one wholly so 

 by ventral plate. Anal legs clawless. Pairs of legs, one hundred and eighty-one. 



One specimen from Claremont collected by W. C. Spencer. 



Gosiphilus laticeps Wood 



A long and slender species with the body conspicuously flattened dorso- 

 ventrally. Pairs of legs somewhere near eighty-one, which is a common number. 

 The antennse are short and conspicuously attenuate distad, contiguous at base. 

 The cephalic plate is wide caudad and strongly narrowed forward. Spiracles 

 small, all circular. Ventral pores in a transversely elliptic area. Last ventral 

 plate wide, sides straight, moderately converging caudad. Coxopleural pores 

 usually, at least, not evident. 



Specimens have been examined from Pacific Grove, Claremont, Los Angeles 

 and Catalina Island. It is common in Texas, the type locality, and the author 

 has also secured it at Las Vegas, Nevada, where it was dug up in a garden.
