9. T. intermedia, Biitschli. grist bei mm. Head truncate, with six cephalic 
setee, each about one-fourth as long as the head is wide, with a row of papillee inside 
the setz ; cesophagus conoid, half as wide as the neck ; intestine at once two-thirds 
as wide as the body ; rectum half as long as the anal body-diameter ; pseudo-bulb 
present, irregular ; vulva very prominent. 
Hab.—Roots of grass, Frankfort-on-the-Main, Germany. 
10. T. filicaudata, de Man. {43 ee ™ 2mm. About eight hundred trans- 
verse strize traverse the cuticula. The truncate head bears four submedian sub-cephalic 
setee just behind the six stout acute cephalic sete (the latter one-third as long as the 
head is wide), and two rows of papillee round the mouth. The cesophagus is nearly 
cylindrical, being only slightly narrower in the middle than elsewhere. The tessel- 
lated intestine ends in a rectum two-thirds as long as the anal body-diameter. 
Pseudo-bulb present. The lateral fields are one-third as wide as the body. The tail 
is usually ventrally arcuate and ends in a terminus one-seventh as wide as its base. 
The vulva is prominent and projecting. The eggs are nearly as wide as the body 
and twice as long as wide. The ovaries extend one-third the distance back to the 
vulva, £2345 17mm. Fourteen or fifteen accessory organs form a ventral row 
reaching from the anus to near the mouth. The nearly straight cuneiform spicula 
equal the anal body-diameter in length and are stiffened by central pieces of chitin. 
There are no accessory pieces.

of papillz both inside and outside these sete ; cesophagus conoid, anteriorly one-half, 
but posteriorly two-thirds as wide as the neck, hardly enlarged anteriorly ; intestine 
tessellated, two-thirds as wide as the body ; rectum nearly equalling the anal 
body-diameter in length ; pseudo-bulb present ; terminus one-fifth as wide as the 
base of the tail; vulva projecting ; ovaries reaching nearly back to the vulva. 
g_2 2 —M— # .7mm. Row of ventral accessory male organs extending forward to near 
the mouth; spicula arcuate-cuneiform with a central stiffening piece, four-fifths as 
long as the anal body-diameter ; accessory pieces rudimentary ; blind end of the
