lormiiig a club in union with the sixth, which is smalL Thoracic 
segment twice as long as the others. Apex of abdomen rounded, 
with a vertical slit; the penultimate ring with the centre a little 
angulated, and lapping over the apex, but not mucronated (c). 
This is a large species, and similar to the following; but there 
are gigantic Snake-millipedes in South America, as thick as one s 
little finger, and upwards of half a foot in length. Juhis Lon- 
dinensis was so named from its having been first discovered in the 
neighbourhood of the metropolis ; and it infests the roots of wheat 
in Surrey, from whence I have received specimens at the end of 
April, which had not arrived at their full growth. 
18. Julus terrestris, Linnanis, the earth Snake-millipede. 
Shining, cylindrical, and piceous ; rather strongly striated longi- 
tudinally ; the edges of the segments brownish, a line of indistinct 
black pores on each side ; the legs ochreous ; eves black, and 
granulated ; antennre longer than the first thoracic segment, which 
is larger than the others, seven-jointed, basal joint globose, four 
following elongated, clavate, truncate, the last being the stoutest, 
and forming with the sixth and seventh a little oval club, the 
apical joint being minute (b j ; penultimate segment of abdomen 
mucronated (a), the lobe subtrigonatc, the tip rounded. 
This species greatly resembles the foregoing, but the spined 
tail and longer antennae readilv distinjruish it. I remember one 
being discovered inside a rotten pear. 
19. Julus punctatus. Leach, the dotted Snake-millipede, is 
often an inch long, but rather slender, cylindrical, and of a testa- 
ceous brown or ochreous colour ; the margins of the segments are 
finel)' and very closely striated ; the crown of the head and 
thoracic segment are freckled, the penultimate one is mucronated, 
the lobe oval ; face, antennHe and legs, pale ochreous ; eyes grey, 
granulated with black. When alive this species is of a some- 
what pellucid pale fiesh-colour, every segment with a black dot 
forming a line down each side. 
I generally find this Julus amongst the moss on old stumps, 
and under stones in woods ; but I think I have received it with 
the other species from gardens. 
20. Jul us latistriatus, Curtis, 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 approxi- 
mating ; down each side is a row of dots, and the penultimate 
segment is not mucronated, but slightlv angulated and rounded, 
as in Juhis Londinensis ; the antennae are stout and rather short, 
pilose and capitate, second jomt the longest, the apex very pu- 
bescent. 
This Julns I took at first for the young of J. Londhwmis, but 
the striae are twice as far apart as in anv other species I have esa-
