BRADE and BirkS — Irish Chilopods. 
129 
The number of individuals examined amounted to of the adult 
form : 40 ; fairly mature : 10 ; immature : i. 
Most are from Bohemia, Moravia and Silesia ; I have also taken tlie 
animal in the Austrian highlands, especially in the southern Tyrol, where 
it was also found by Meinert. 
Observation i.— On the under side of the 3rd joint of the anal leg: 
The fourth spine which Meinert does not mention, is inserted in the sa me 
transverse row as the three normal spines, but more on the innersidc. 
Indeed it could even be counted with the spines of the dorsal surface, 
but I think that the formula given is the more correct. This latter is 
very seldom too low for adult animals, indeed it may even become 2 above 
the stated number, by the addition of inwardly directed spines on the 
above-named joint. 
Observation 2. I sent some of the individuals upon which this descrip- 
tion is based to Dr. Meinert, who referred the same to his Lithobius lapi- 
dicola, although I had thought to put them down to his Liihobius borealis. 
At all events the latter is nearly related to L. lapidicola} 
There were seven specimens of Liihobius lapidicola in 
the material collected on Sugarloaf, and a consideration 
of these enables us to offer some notes which may be of 
service to other workers. Our specimens agree in the main 
with the details given in Latzel's study, but even in the 
small number of examples at our disposal many individual 
peculiarities occur. These will be noticed in the following 
account : — 
Body fairly flat, with the whole of the surface and that 
of the appendages finely granulated, spindle-shaped, widest 
about the loth segment. Spirit specimens show great 
\^ariation of colour in different parts of the body from dark 
brown to pale yellow ; the anterior portion of the cephalic 
shield, the mid-dorsal line, and the edges of the dorsal 
plates tend to be darkest, while there is often a light patch- 
in the case of the dorsal plates on either side of the mid- 
dorsal line. 
The ventral plates are light yellow, the posterior appen- 
dages are darkest, the anterior ones are pale yellow. 
The general proportions of the Irish specimens seem to 
be in agreement with those Latzel notes. The dimensions 
which follow are those of a male : length, iimm. ; width 
of the 8th dorsal plate, 1.3mm. ; length of antennae : 
left (32 segments) : 4.5mm. ; right (29 segments) : 4.4mm.
