humus-like substance ; they are 43 — 51 /* long and about 

 half as broad (fig. 2/). The tail of the female (PL IV, 

 fig 2 e) is slender, elongated, and tapers regularly towards 

 the hair-fine termination ; it shows the peculiar character 

 that at a slight distance behind the anus the internal layers 

 of the cuticula diverge from the external, being separated 

 from one another by a light coloured one. 



The movements of these graceful worms are about as 

 active as those of the other species of this genus. 



Bhabditis coronata was discovered by Cobb in humus 

 about the roots of banana plants, Fiji Islands, July, 1891. 



3. — Bhabditis oxycebca, n. sp. — Fig. 3. 



Male and female 0"97 mm. ; a in the male 16 — 17 J, in 

 the female 15—21 ; /? = 4— 4J ; y in the male 23—27, in 

 the female 35 — 45. 



This interesting new species, numerous individuals of 

 which have been observed by me, both males and females, 

 in the diseased tissue of the Galanthe, presents (especially 

 on account of the shape of the tail in the female) some 

 resemblance with Bhabd. teres, Schn., but is distinguished 

 from all other species by the quite different distribution 

 of its eight bursa-ribs, and, moreover, by some other 

 characters. 



Bhabditis oxycerca, thus named after the short mucro~ 

 nated tail in both sexes, attains scarcely the length of one 

 millimeter, and ought accordingly to be reckoned among 

 the species of small size. The body of these parasites 

 appears more or less stout, plump, not slender, both in 

 the male and in the female, though the general form of 

 the body of the female varies somewhat according to the 

 uterus being filled or not with eggs and embryos. The 

 anterior oesophageal part of the body tapers rather much 

 anteriorly, so that the head-diameter at the base of the
