intestine is two-thirds as wide as the body, its cells containing coarse granules. 
The cardia is deep and the cardiac cavity is distinct. The anterior half of the tail is 
conoid, the posterior half setaceous. The reflexed ovaries reach nearly to the slightly 
projecting vulva. The thin-shelled eggs are two-thirds as long as the body is 
wide and two-thirds as wide as long, and begin segmenting while in the uterus.

= se as 9730 mm. The anterior two-fifths of the male tail is conoid and ventrally 
arcuate ; thence it is setaceous. The anal region is slightly elevated. Of the male 
papillze at least all three pairs of the closely approximated third group and four other 
pairs are present. Of these latter four, three pairs occur opposite the middle of the 
spicula, two being ventrally submedian and close together, and one lateral, slightly 
farther back ; the fourth pair—lateral—is as far behind the anus as the foremost of 
the other three is in front of it. The closely approximated three pairs, situated where 
the tail suddenly narrows, are associated with a slight ventral swelling. The spicula 
are linear, gently arcuate and nearly twice as long as the anal body-diameter. The 
slender accessory pieces are somewhat sigmoid in form, their internal ends turning 
forward, while their opposite ends are applied to the distal parts of the spicula. * Only 
a small portion of the testicle is reflexed. The testicle and vas deferens are of about 
equal length.

marked transversely by very fine striz. The pharynx is as deep as the head is wide, 
and, when seen in profile, appears much narrower in its posterior half than in its 
anterior half because of the presence in the posterior part of the large and pointed 
dorsal tooth ; anteriorly the pharynx is half as wide as the head. The ellipsoidal 
median bulb is two-thirds as wide as the neck and is less elongated and more pro- 
nounced than the posterior bulb. The tubular part of the cesophagus is rather uniform 
in diameter, the anterior half being but little wider than the posterior half. The 
ventral excretory pore is situated somewhat nearer the cardiac than the median bulb. 
The granular intestine is three-fourths as wide as the body. The anterior fifth of 
the tail is ventrally arcuate and conoid; thence onward it is setaceous. The arcuate- 
cuneiform spicula are equal to the anal body-diameter in length and are supplied with 
arcuate accessory pieces half as long. These latter are slender and make a slight 
angle with the spicula. Six pairs of papille were seen: 1, a ventrally submedian 
pre-anal pair opposite the proximal ends of the spicula; 2, a ventrally submedian 
pair somewhat behind thé anus; 3, three approximated submedian pairs somewhat in 
front of the place where the tail becomes rather suddenly setaceous; 4, a dorsal pair 
(or only one, | am not positive) somewhat behind the three pairs just mentioned.
