ing. One lobe narrower and styliform. I am not quite certain 
whether our specimen is quite identical with the species of 
Villot ; for he mentions nothing specially of the form of the 
extremity of the tail, and in our specimen the unequal lobe is 
so much narrower that it might be rather called a rod than a 
lobe. The lobes are so closely united that one can hardly 
distinguish them with the naked eye. In other respects it 
agrees with Villot’s description. 
Hab. Lima (Peru). 
12. Gordius diblastus, n. sp. (Pl. XVIIL. fig. 6.) 
Female, length 40 centim. ; male, length 16-20 centim. 
Body slender, tapering at both extremities, especially poste- 
riorly. The extremities are somewhat swollen and button- 
shaped. The tail of the male has two lobate processes of 
nearly equal thickness throughout their whole length. Thick- 
ening in the region of genital aperture inconspicuous. Cuticle 
with very slightly raised crossing lines, and covered with pale 
spots. 
Hab. New Zealand. 
13. Gordius pachydermus, n. sp. 
(QB, SCWIUOL, te, 05) 
Male, length 16-20 centim. 
This species is especially distinguished by the thickness of 
its cuticle, which is covered with a great many more or less 
elevated papillee of various sizes. No crossing lines are to be 
seen ; and the cuticle appears almost structureless. 
Body of a red-brownish colour, tapering continuously at the 
extremities, especially at the anterior. Semicircular depres- 
sions giving rise to a superficial segmentation. ‘Tail of the 
male has two lobate very short processes, equally broad 
throughout their whole length, running almost parallel and 
not touching each other. ‘The horseshoe-shaped thickening 
in the region of the genital aperture inconspicuous.
