This latter seems merely to be produced by the entanglement of the
single threads. The spiders were all of one species, but of both
sexes, together with young ones. These latter were distinguished by
their smaller size and more dusky colour. I will not give the
description of this spider, but merely state that it does not
appear to me to be included in any of Latreille's genera. The
little aeronaut as soon as it arrived on board was very active,
running about, sometimes letting itself fall, and then reascending
the same thread; sometimes employing itself in making a small and
very irregular mesh in the corners between the ropes. It could run
with facility on the surface of water. When disturbed it lifted up
its front legs, in the attitude of attention. On its first arrival
it appeared very thirsty, and with exserted maxillae drank eagerly
of drops of water; this same circumstance has been observed by
Strack: may it not be in consequence of the little insect having
passed through a dry and rarefied atmosphere? Its stock of web
seemed inexhaustible. While watching some that were suspended by a
single thread, I several times observed that the slightest breath
of air bore them away out of sight, in a horizontal line.
