the passage ways and galleries of a nest of Termites or white ants, 
and I think it likely that this and FR situations will turn out 
to be their favorite haunts. e singular activity of the little 
creature as compared with that of te small Collembola and crus- - 
taceans which were its companions was very striking and ren- 
dered it very evident that we had encountered an organism which 
until then had escaped our observation. The little fellows when 
roughly handled rolled themselves up and “played possum,” as 
do some Diplopods. They also seemed to be very sensitive to 
contact with a pointed style with which I frequently touched 
them, and which I think they perceived by means of the long 
lateral bristles of which there are four on each side as well as by 
means of the antennz. Much more active and quick in move- 
ment than Polyxenes, resembling in this respect the Chilopods, I 
am inclined to think that they are undoubtedly Myriapoda. Also 
the fact that I found many specimens with but three and four 
leg bearing segments is also evidence that they moult several 
times, as do their immediate allies, in passing from the immature 
to the adult state. As Lubbock has found the spermatozoa, and 
also noticed most of the other facts here mentioned, I would 
merely state that I have been so explicit only because desirous of 
confirming what seems to me to be that naturalist’s just conclu- 
sions in regard to its myriapodal affinity. The species which I 
have found is white and is about 1-25th of an inch in length, which 
_ renders it a good subject to try the eyesight of a collector. With 
a magnifying power of a thousand gees the styles or bristles 
which terminate the antennæ are seen to be made up of a great 
number of superposed disks or rings, ee rT have been unable to de- 
cide whether they are mere annular processes encircling the central 
axis of the style, or whether they are separate segments, though 
= flexibility of the styles would indicate that they were seg- 
ented. The clavate hairs are in like manner annulated— vo.
