Cobb — Nematodes, mostly Australian and Fijian. 35 



spreading setae arranged in the usual manner, four, i.e., one of each submedian pair, 

 being half as long as the others, these latter measuring one-half as long as the 

 tiead is wide; lips three, each with two papillae; lateral organs probably represented 

 by small elliptical markings no wider than the base of the cephalic setae and 

 situated at a distance from the anterior extremity nearly equal to the width of the 

 head ; eyes none ; pharynx infundibuliform, simple ; oesophagus sub-cylindrical, one- 

 third to three-fifths as wide as the neck, widest at the pharynx and posteriorly ; 

 cardiac coUum distinct; intestine three-fourths as wide as the body, loosely granular 

 aiid quite transparent ; rectum two-thirds as long as the anal body-diameter ; no 

 ventral gland seen ; nerve-ring encircling the oesophagus squarely, half as wide as the 

 oesophagus at the point encircled; body diminishing suddenly in size near the anus; 

 tail conoid to the middle, where it is one-third as wide as at the anus, thence more or 

 less cylindroid to the conoid terminus, which contains a small outlet for the secretion 

 of the caudal glands; anus depressed, more or less open; vulva not very prominent; 

 eggs three to four times as long as the body is wide and one-fourth as wide as long; 

 reflexed portion of the ovary reaching nearly to the vulva. Several drawings of this 

 little worm will be found on PL iv.

7. T. monhystera, de Man. ^2 ? ^' ~1- "^X-i ^'^ """■ The smooth cuticle bears four 

 sub-cephalic setae behind the six slender cephalic setae, the latter being half as long as 

 the head is wide. The truncate head bears papillae round the mouth. Lateral 

 organs are perhaps present. The conoid oesophagus, which is a trifle enlarged in the 

 anterior fourth, is posteriorly one-half, though anteriorly one-third, as wide as the 

 neck. The intestine is three-fourths as wide as the body and ends in a rectum about 

 as long as the anal body-diameter. The terminus is very narrow, but mucronate. 

 The eggs are over three times as long as the body is wide and one-fifth as wide as 

 long. The male is unknown.

8. T. marina, Blitschli. "-s ? '3-9 '%% %& i-smm. Cuticle smooth; cephalic setae six, 

 nearly one-third as long as the head is wide ; lumen or lining of the oesophagus 

 widened behind the mouth ; intestine half as wide as the body, thin-walled, with a 

 large cardiac cavity; lateral, median and submedian fields present, the first perhaps 

 half as wide as the body; anterior two-thirds of the tail convex-conoid, thence having 

 a uniform diameter one-fifth as great as at the base ; jTI — f9~~? — 3^ ^'^ '""'• Spicula 

 cuneiform, three-fifths as long as the anal body-diameter, slightly bent near the 

 middle; accessory pieces small, quadrangular.
