DIPLOPODA OP LIGURIA 507 



equal to the width of the liead, the last segment long and 

 conical, almost or quite as long as the penultimate which is 

 about twice as long as wide, the antepenultimate about as long 

 as the two just described taken together. 



Anal tuft long and narrow. 



The rest of the body apparently as in P. Uujurus. 



Length up to nearly 4 mm. 



Locality: Nervi. On the open liill-sides beneatii stones, some 

 four or five hundred feet in altitude. 



This species differs from all the other species of the family 

 in the absence of eyes; it is further remarkable for the great 

 length of the antennae. We thus see that the loss of the organs 

 of sight is compensated for by the greater development of the 

 organs of touch. 



In the length of its antennae it closely resembles P. lucidus 

 of Chalande (see Silvestri, Boll. Soc. Rom. Zool. Ill, 1893). But 

 the latter species is provided with well developed eyes.
