Sinclair (1904), in addition to references to two of the cases 
cited above, adds an instance, with which the writer is other- 
wise unfamiliar, from Verhoeff; this concerns Brachydesmus 
superus, “which,” says Sinclair, “ live in dry seasons beneath 
the earth and in rainy weather are found above the ground : 
in the latter case they make short migrations.”

Movements of Millipedes at Night. 
At Wye, Kent, in 1921, I was fortunate in being able to 
make first-hand observations over a period of several months, 
On 6th April, between 8 and 9 p.m., G.M.T., I was walking 
with a colleague, Mr. C. A. W. Duffield, along a road close 
to the town (Coldharbour Road), when, by the light of the 
lamp carried, a number of millipedes was seen in the roadway. 
On many subsequent nights during the months of April, May, 
and June, I searched the same road, and repeatedly found 
millipedes. ‘l'wice in July (19 and 20) when I searched I 
found none. In the course of three months the following 
animals were obtained in this way :— 
Tuchypodviulus niger (Leach). 
Cylindroiulus londinensis, var. ceruleocinctus (Wood). 
Lulus (Micropodoiulus) scandinavius, Latzel. 
Ophytulus pilosus (Newport). 
Schizophyllum sabulosum (Linné). 
Stosatea italica (Latzel) [now first recorded for Britain ; 
see remark at the end of this note]. 
Polydesmus sp. 
I believe that the -millipedes observed on this road were 
mostly individuals of the first two forms mentioned in the list 
just above. Support is given to this view by the fact that 
on the first two nights of observation—nights when large 
numbers were observed—complete diagnosis of the animals 
collected showed that there had been obtained 24 7. niger, 
1 C. londinensis, var. cvruleocinctus, 1 Polydesmus sp., in a 
distance of about 240 yards on 6. 4. 21, and 70 7. niger, 
11 C., londinensis, var. ceruleocinctus, 1 or 2 IL. scandinavius, 
and 1 Polydesmus sp. in a distance of about 530 yards on 
7. 4. 21 (both distances are but roughly determined ),
