Probably tracheae have developed independently by the same process in several groups of tracheate Arachnids.

The fibres are frequently found in tangential bands between similar bands of tracheae or sieve-tubes.

In Velella the pneumatophore becomes of complex structure and sends air-tubes, lined by a chitin and resembling tracheae, down into the compact coenosarc, thus evidently serving a respiratory as well as a hydrostatic function.

The appearance of tracheae in place of lung-sacs cannot be regarded as a starting-point for a new line of descent comprising all the tracheate forms; From Lankester, Journ.

In Peripatus the stigmatic pits at which the tracheae communicate with the atmosphere are scattered and not definite in their position.

In regard to tracheae the very natural tendency of zoologists has been until lately to consider them as having once developed and once only, and therefore to hold that a group " Tracheata " should be recognized, including all tracheate Arthropods.

The possession of gill-slits is as interesting a feature in the organization of Balanoglossus as is the presence of tracheae in Peripatus.
