and much like that described by de Man in his A. microphthalmus. 
It is situated about 5 (i behind the front. 
The buccal cavity is very narrow, almost tubular. The oeso¬ 
phagus, the length of which makes 200 ju, has immediately caudad 
to the eyes a bulb-like dilatation recalling the wellknown bulb in 
the middle of the oesophagus in the Rhabditidæ. It is almost ovoid 
in shape and includes a cavity. The nerve ring is very distinet 
and situated 120 /li from the front end. At its base the oesophagus 
narrows strongly, and its proximal end forms a blunt cone pro- 
jecting somewhat into the lumen of the intestine. This is spacious, 
and its cells are filled with strongly refringing granules. 
The ventral giand is in the Auckland species very large and 
occupies a considerable space in the body cavity; it forces aside 
the intestine and compresses it strongly. In its interior a large 
nucleus with a little refringing nucleolus is seen. The exeretory 
duet opens 24 /li from the front end by a fine tube issuing from 
a rather large, pear-shaped ampulla. 
The vulva is situated somewhat cephalad to the middle of the 
body. The ovaries are symmetrical and reflexed. 
Parasabatieria de Man. 
Parasabatieria Movtenseni n. sp. 
PI. II, lig. 2. 
Locality : Auckland Islands. North-arm of Carnley harbour. Clay. 
Length: Female 2 mm. Male 1,9 mm. 
Female: a — 45. ft — 9. y — 16. 
Male: a = 46,5. ft = 9,3. y =■ 15,5. 
A considerable material of this species is at my disposal, in all 
16 males and 39 females. 
The body is rather siender and of about the same width through- 
out the greater part of its length. The head is — as is the case 
too in the genus Sabatieria — separated from the body by a con- 
spieuous constriction. In both sexes the tail is rather short; it 
tapers evenly from the anal opening and ends in a little dilatation 
on the tip of which the duet of the caudal giands opens. In the 
region of the genital organs the body of the female is often con- 
siderably expanded by these; also the ventral giand, which is of
