36 Cobb — Nematodes, mostly Australian and Fijian. 



9. T. intermedia, Blitschli. "ig \ l-e '1' % i"™- Head truncate, with six cephalic 

 setae, each about one-fourth as long as the head is wide, with a row of papillae inside 

 the setae ; oesophagus '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. 



ZTa^.— Boots of grass, Frankfort-on-the-Main, Germany. 



10. T. fllicaudata, de Man. X-r, \ Xi 'l-f '^X-^ ^'^'^ About eight hundred trans- 

 verse striae traverse the cuticula. The truncate head bears four submedian sub-cephalie 

 setae just behind the six stout acute cephalic setae (the latter one-third as long as the 

 head is wide), and two rows of papillae round the mouth. The oesophagus 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 ventraUy 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. 1-6 ? ^2-4 "s To i'^"™- 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. 



Hab. — Found in moist earth, Holland ; not common.

11. T. setifera, Biitschli. \. \ ^! '^g-'g — %^ \-nmm. Cuticle finely striated; head trun- 

 cate, with six cephalic setae, each nearly half as long as the head is wide, and a row 

 of papiUae both inside and outside these setae ; oesophagus 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. 

 2" ; ^3-5 ~3^ 3*4 1'^™"- 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 

 anterior testicle lying near the commencement of the middle third of the body. 



Hab. — Marshy earth, Holland ; roots of a fungus, Germany.
