10 Q(ye%— Nematodes, mostly Australian and Fijian. 



ovaries are short. ' ^ 27 T i'^""- The tail of the male resembles that of the female 

 in form. A ventral row of ten to eleven large papillae occurs in front of the anus. 

 Dorsal as well as ventral papilljB are found on the tail. Each of the two equal 

 arcuate spicula is stiffened by an extra central piece of horn. The accessory piece is 

 two-parted and surrounds the spicula. 



Hab. — Soil in meadows, Western Europe ; common. 



7. M. parvus, de Man. r H Zn '1-2 1" ii-""- The conoid neck terminates in a 

 head with an expanded lip-region bearing the usual two circles of papillae of which 

 the inner are the larger. The pharynx is a little over one-third as wide as the head, 

 the dorsal tooth being small and central. There are two small submedian teeth at 

 the base of the pharynx. The intestine is two-thirds as wide as the body and ends 

 in a rectum two-thirds as long as the anal body-diameter. The reflexed ovaries reach 

 three-fourths the way back to the vulva. 



Hab. — This active species is common in sandy meadows, Holland. 



8. M. cristatus, Bastian. 3-8 ? T/^s-t 1-2 I'l-""- The CESophagus is about half as 

 thick as the neck. The intestine is two-thirds as wide as the body and ends in a 

 rectum two-thirds as long as the anal body-diameter.

9. M. minor, n.sp. An immature female gave the formula 3:1 — 3-7 4-3 4-3 27 ^■'"™- 

 The head is less truncate than usual. What appear to be lateral organs occur 

 opposite the anterior part of the pharynx. This latter is pyriform, being broadest 

 anteriorly and is approached through a narrow vestibule nearly one-third as long as 

 itself The thumb-shaped dorsal tooth projects half way across the pharyngeal 

 cavity somewhat above the middle, and is opposed by half-a-dozen transverse rows of 

 rasp-like teeth one micromillimetre apart, the upper of these rows being opposite the 

 apex of the tooth and the lower opposite its middle. The intestine is three-fifths as 

 wide as the body, and the rectum is nearly equal to the anal body-diameter in length. 

 The lateral fields are one-third as wide as the body. The terminus of the tail is one- 

 third as wide as the base. The anatomy of this worm is well set forth on PI. i.

10. M. papillatus, Bastian. 23 ? s-s — ? — m is to 2-6 mm. The triquetrous pharynx is 

 about one-third as wide as the head, and has the rather small dorsal tooth situated 

 a little in front of the middle. The intestine is two-thirds as wide as the body. 



Hab. — Among moss and grass, Western Europe ; common.
