(PI. XXII, figs. 1, 2 and 3). 
Dimensions: 
d Length: 25 to 31 mm.; width: 1,5 
to 1,6 mm. 
Q Length: 24 to 31 mm.; width: 1,6 
to 1,8 mm. 
Body cylindrical somewhat attenuated 
at extremities. Tegument opalescent, but still 
transparent enough to allow one to see the 
white colouring of the genital organs and 
the dark red of the digestive tube. Cuticle de- 
licately transversally striated; the striations 
being 0,0015 mm. distant from one another 
in the cephalic region where the cuticle se- 
parates from the sub-jacent layer, the distan- 
ce between the striations reaches 0,0065 
mm. Polymiarian musculature. Very complex 
mouth (vid. figs.1 and 2), lengthened dorso- 
ventrally. Dorsal commissure occupied by a 
strong first tooth, trilobate like an ivy-leaf, 
moving round the base; the lateral borders 
re-inforced by chitinous formation, segmented 
in four departments with a great number of 
plates arranged in groups and bent towards 
the centre. Six cephalic papillae: two double 
Note (1). Leidy and Railliet & Henry give as hosts 
two tortoises from Java: Testudo sp. and Manouria fusca 
According to the catalogue of the British Museum, the 
species Manouria fusca (Gray) corresponds to Testudo 
emys Schleg., This latter name ought to be adopted in 
preference to the other. This being the case perhaps 
Cissophyllus laverani of Railliet & Henry might be iden- 
tified with Cucullanus roseus of Leidy, though we cannot 
affirm it as we are uhable to consult Leidy’s descriptions.
