a transverse band ; posterior border of the anterior scuta produced back- 
wards from the sides to the middle, there touching or slightly overlapping 
the succeeding plate, exposing the praescutum of the latter only at the sides ; 
posterior borders of plates after the twenty-second straight. 
Legs, excepting ultimate, pilose with moderately long straight hairs ; 
first pair more slender than others, not much shorter ; anterior pairs much 
stouter than the posterior, not much shorter; anallegs much swollen, claw 
obsolete, clothed more densely and, more often, with shorter hairs than 
pairs preceding. 
Pleurz of last segment not much inflated, with about twelve pores of 
several sizes, these arranged subseriately, partly covered by the last ventral 
plate; last ventral plate wide, much wider than long (1.85 : 1), sides con- 
vexly curved, converging posteriorly. 
Pairs of legs of male 69. Length of male 29 mm., width .7 mm. 
Habitat. — The type specimen, a male, was found buried in damp saw- 
dust under a piece of timber, Salt Lake City. 
The type was taken June 3, 1900. 
Geophilus glyptus sp. nov. 
Description. — Body robust, caudad strongly, cephalad but little attenu- 
ated; head pilose at sides, more especially posteriorly, basal plate and 
exposed dorsal portions of prosternum more densely pilose, prosternum 
ventrally subglabrous, first dorsal plates sparsely provided with short hairs, 
the plates caudad becoming subglabrous, ventral plates glabrous ; head 
and prosternum with the prehensorial feet chestnut, body above and below 
amber brown, or in middle portions yellowish, legs and antenne concolorous 
with the body. i 
Antenne short (3-3.4 mm.), stout, attenuated from base distally ; first 
four or five joints sparsely provided with long hairs, the others with shorter 
hairs, which decrease in length and increase in density toward ultimate 
article ; articles long, the ultimate shorter than the two preceding taken 
together. 
Cephalic plate a little longer than wide (9: 8.2 nearly) ; posterior mar- 
gin truncate, anterior margin extending forward from the sides to the 
middle, sides rounded, impressed with two lateral and a single median 
sulcus; basal plate partly covered, exposed portion over four times wider 
than long. 
Claws of prehensorial feet not much curved, when closed reaching to or 
a little beyond the distal end of the first antennal article; each claw armed 
at base with a moderately small obtuse tooth ; inner side of coxa short or 
very short, unarmed ; prosternum wider than long (not quite 9:8), over 
twice the outer height of the coxa; anterior margin widely sinuate. 
Dorsal scuta impressed with two lateral and a single deep median sulcus ; 
anterior prescuta very short, middle long or very long, posterior short.
