II. A new mode of respiration in the myriapoda

In the course of some work which I have been doing lately, 1 have been led to consider the systematic position of the Scutigeridæ or Cermatidæ. C. L. Koch, in his well known work, “System der Myriapoden,” includes this group in an order by itself, dividing the Myriapods into three orders of ecpial value. These orders are the Chilognatha, the Chilopoda, and the Schizotarsia (the Scutigeridæ). Latzel, on the other hand, and with him most other writers, have included the Scutigeridae among the Chilopoda, not considering the differences to be of sufficient value to warrant the formation of a new Order. I came to the conclusion that so little was known of the Scutigeridæ that Latzel was quite right in including them among the Chilopoda; but that a more careful study of their organisation might very likely render it necessary to modify that view, and show that Koch was right in his establishment of a new Order, although, in the absence of published facts, his doing so might be premature.
