Notes on Myriapoda. 255 
29. Cylindrotulus latistriatus (Curtis). 
In 1844 John Curtis, F.L.8., contributed a paper (3) to 
the ‘Journal of the Royal Agricultural Society,’ in which he 
gave a brief description of several English Diplopoda. One 
of these he calls ‘“‘Julus Londinensis of Leach,” and gives 
two excellent figures, which show conclusively that even at 
that early date the typical “ Julus” londinensis, Leach, was 
confused with the animal often known since (especially on 
the continent) under that name, for Curtis’s figures are 
obviously of Cylindroiulus londinensis teutonicus (Pocock), 
which is tailless, whereas the true Cylindroiulus londinensis 
(Leach), which Curtis thought he was figuring, has a clubbed 
tail and is a much larger animal. What Curtis meant by 
« Julus Londinensis of Leach” is important when we come 
to his description of “ Julus”’ latistriatus. 
Curtis (oc. cir.) tells us that his specimens of latistriatus 
were sent to him from Namptwich (Nantwich), Cheshire, 
where they constituted a pest in garden and greenhouses. In 
London we saw the specimens Curtis presented to the 
British Museum (5), and we must regard them as his types. 
Iixternally they agree with Cylindrotulus britannicus (Ver- 
hoeff), and when we remember that this species is well 
established in the north of England (it is a pest in a green- 
house at Darwen, Lancashire), we can have little doubt about 
the synonymy of the two. For these reasons we strongly 
advocate the restoration of the specific designation used by 
Curtis and the rejection of that of Verhoeff which was 
established in 1891. 
Curtis’s paper (3) was overlooked by Latzel when he 
compiled the bibliography for his monumental work (4), and 
it is probably unknown to many myriapodologists. We 
therefore append the original description of the species 
with which we are now especially concerned :— 
“Julus latistriatus, Curt?'s, the broad-lined Snake-millipede, 
is 5 or 6 lines long, of a dull ochreous lilac with a purple 
tint, cylindrical, very shining, sparingly striated, the lines 
not approximating ; down each side is a row of dots, and the 
penu timate segment is not mucronated, but slightly angu- 
lated and rounded, as in Julus Londinensis ; the antennz are 
stout and rather short, pilose and capitate, second joint the 
longest, the apex very pubescent.” 
Curtis adds that he at first took this “Judus’’ for the 
young of “ londinensis,” but that the strie were twice as far 
apart as in any other species he had examined.
