Last ventral plate narrow, the sides converging posteriorly and 

 the posterior margin straight. Pleural pores situated ventrally 

 and laterally; a few covered by the last plate and one somewhat 

 isolated caudo-laterad from the others of the ventral group; sixteen 

 or eighteen in number. 



Anal pores not evident. 



Pairs of legs 73. 



Length 42 mm. Width 1.1 mm., nearly. 



Locality — Not definite, but probably California (southern 

 portion, if so). One specimen. 



17. Geophilus claremontus sp. nov. Plate XXV, figs. 7, 8, 9. 



Scarcely attenuated anteriorly; abruptly narrowed caudad. 



Cephalic plate longer than wide in ratio of 2.7:2; about equal in 

 width anteriorly and posteriorly ; anterior and posterior angles widely 

 rounded ; posterior margin subtruncate or very weakly excurved ; mid- 

 dle portion of lateral margins straight or but slightly excurved. 

 Marked with two longitudinal and diverging sulci in front of posterior 

 margin. Punctate with coarse and fine punctae, the middle portion 

 of frontal plate free from such punctae or nearly so. Frontal plate 

 discrete. Portion of the basal plate uncovered by the cephalic 2.6 

 times wider than long. 



Claws of prehensorial feet when closed extending to middle of sec- 

 ond antennal article. Feet armed on each side with four teeth, that 

 on the claw longest, truncate; that on the femur broad but low, 

 rounded, the other two similar but smaller. Presternum wider than 

 long (4.8:4.5); anterior margin widely emarginate, the emargifiation 

 shallow; marked with a median longitudinal sulcus. 



Dorsal scuta strongly bisulcate; punctate. Anterior prescuta 

 short; prescuta back of the middle becoming moderate and then 

 decreasing, the ultimate being very short. 



First spiracle large, sub-circular, being a little elongate vertically. 

 Other spiracles circular, the third much smaller than the first and 

 the second intermediate in size; others gradually decreasing in size 

 from the third caudad. 



First pair of legs decidedly shorter and more slender than the sec- 

 ond. Ultimate legs slender, armed with a claw. 



Ventral pores not detected. 



Last ventral plate moderate; narrowing caudad; sides a little ex- 

 curved as is also the posterior margin. Pleural pores ventral in posi- 

 tion ; the one most posterior in position somewhat isolated from the 

 others; about fifteen on each side, an inner row of them being covered 

 by the last plate. 



Pairs of legs 65. 



Length ad 40 mm. Width ad 1.2 mm. 



Locality — Claremont, Cal. 



One specimen. Apparently related rather closely to legiferens 

 sp. nov.
