A few experiments were made on Myriopods. The presence of damp 
earth was found to prolong the duration of movements after decapita- 
tion. Both body and head of Scolopendra have been found to move 
eight days after having been separated from each other. Geophilus 
shows no signs of inconvenience after being deprived of its head ; speci- 
mens have lived for ten days after the operation. lulus continues to move 
its legs, especially the terminal joints, for seven days, and the antennae 
for forty-eight hours, after the head has been separated from the body.

Commenting on Guldensteeden-Egeling’s discovery of prussic acid in 
a species of Fontaria inhabiting hothouses in Holland, Cope mentions that 
a common Pennsylvanian Myriopod, Fontaria virginica , emits a strong 
odour of prussic acid.

S. coleoptrata occurs in a paper mill near Aberdeen, having probably 
been introduced in bundles of rags from the south of Europe.

Scolopendrella has two stigmata situated on the under side of the head, 
beneath the base of the antenna?. From these a tracheal stem, whose 
walls have not spiral thickenings, runs backwards as far as the base of 
the head, where it breaks up into a system of air-tubes, supplying the 
fore part of the body. The chitinous tubes which Ryder has described 
are not, in Haase’s opinion, breathing organs at all. The tracheal sys- 
tems of Scutigera , Litliobius , Cryptops , Scolopendra , and Himantarium 
are briefly described. From their structure, Haase concludes that the 
tracheal system of the Chilopods shows with the greatest clearness that 
the highest development of the breathing system, that which approaches 
most nearly to the breathing system of insects, is found in the forms 
having many body-segments ( Scolopcndridee and Geophilidai ), his Cliilo- 
poda Fpimorpha , thus furnishing him with another proof of their natural 
separation from the forms with few body- segments, his Cliilopoda Ana 
morpha.
