DIPLOPODA OK LIGURIA 517 



In the Ann. and Mag. of Nat. Hist. (0), XI, p. 24!), I have 

 pointed out that lulus pilosus of Newport was redescribed as 

 fallax by Meinert , according to the diagnosis of this last species 

 that Dr. Porat has recently given. This fallax of Meinert appears 

 further to be the same species as /. longabo of C. Koch and Latzel. 

 Therefore longabo must also be a synonym of pilosus, Newp. 



Now according to Berlese, longabo is a commonish species in 

 Italy. But until specimens of his longabo have been compared 

 with specimens of Koch's longabo from Germany, it seems to me 

 to be permissible to doubt the identification of the Italian spe- 

 cimens. At least I am in a position to assert that I have never 

 seen an italian lulus agreeing with /. pilosus of Newport. 



But in Liguria Mr. Thomas obtained a large number of spe- 

 cimens of an lulus which is certainly very nearly related to 

 /. pilosus and which I suspect is the /. longabo of Berlese. 



These specimens vary very much in size; large 9 examples 

 attain a length of 38 mm., while the c/", which is much thinner, 

 reaches a length of 28 ram. 



There are about 63 or 65 segments. 



This form differs from pilosus in that in the </ the anterior 

 pair of feet are considerably smaller, the distal segment being 

 less openly curved, and in that the stipites of the gnathochila- 

 rium are not swollen. 



As in pilosus the coxae of the second pair of legs are without 

 a process. 



Mr. Thomas obtained this form at Portofino , Nervi , Genoa , 

 Busalla and Monaco.
