New Sj)ec'iex of Peripatoides. 421 



under surface of the body and of the feet is devoid of pi<j:rnent 

 save for insignificant speckles scarcely visible without a lens. 



The whole surface is thrown into a nunil)er of transverse 

 ridges, ornamented, as usual, by papillae, of which two varieties 

 are present — (1) a smaller, and (2) a larger. The former is 

 usually black, the latter has a terminal l)lack part (the ecpiiva- 

 lent in size of the whole of the smaller kind), with a lighter 

 basal part surrounded ))y a light yellowish patch of skin. Eacii 

 of the larger papilhB terminates in a minute colourless spine 

 which is apparently wanting: on the smaller ones. 



The ujencral colour of the bodv is affected, to a large extent, 

 by that of the pai)ill;e. In the greenish coloured specimens they 

 are always black, l)ut in the brownish ones the great majority 

 of them are chestnut-brown in colour. In all cases the rings are 

 continuous across the mid dorsal surface, though they are 

 crossed one after the other by the thin median light line, which, 

 however, in no way affects the continuity of the ridge, and may 

 occasionally be quite wanting, a dark papilla then occupying 

 the very middle line. The papillae throughout are arranged in a 

 single line on each ridge. There appear to be always seven 

 ridges running between each successive pair of legs. 



Ambulatory Appendages. — The claw-bearing legs are sixteen 

 in number,! the first and last being somew^hat smaller than the 

 others. Each has three spinous pads and about eight or nine 

 rings of papillae, which contain only a very mintite amount of 

 pigment on the ventral side of the leg. On the proximal side 

 of the first of the rings, that is, just where the leg joins the 

 body, there is a small but very distinct round opening bordered 

 by «i circle of papillae containing more pigment than those else- 

 where on the ventral surface. This indicates the position of 

 the external opening of the nephridium, and can be seen on 

 every leg except the first and last pairs, though n)ost noticeable 

 in the middle and hinder parts of the body. In front of seg- 

 ment five or six it becomes smaller and more slit-like. 



1 As an abiioniiality one specimen has fif'een \e\is on the left side and sixteen on the 

 rij^ht. The pairs are quite regular as far baok as the thirteenth. The sixteenth pair is 

 normal on each side, ))Ut the one between this and the thirteenth on the left side is 

 opposite the middle of the internal between the fourteenth and fifteenth legs of the 

 right side.
