Abstract

IN No. 423 of the Zoologische Anzeiger (1893) I ventured to propose a new classification of the Tracheata, including under this heading those Arthropoda that are usually known as myriopods and insects. The principal changes suggested were the abolition of the name Myriopoda as indicating an unnatural assemblage of beings and the union of the Chilopoda, Symphyla, and Hexapoda in a division (Opisthogoneata), which was based upon the situation of the generative apertures at the hinder end of the body. But in referring the Symphyla to this category by adopting the assertions of Menge and Latzel respecting the position of the orifices in question, it appears that I fell into error; for Dr. Erich Haase has kindly written to me from Bangkok, with the information that by means of a series of transverse sections he was able, although with considerable difficulty, to confirm Grassi's statement to the effect that the generative apertures in Scolopendrella are situated upon the fourth body-segment. This genus is therefore progoneate, like the Diplopoda and Pauropoda; but whether it should be ranged with these two classes, or occupy an independent position between the Progoneata and Opisthogoneata, is a question for future discussion.
