A study of the Lysiopetalidce has induced Packard to think that Scudder 
was wrong in regarding the Archipolypoda as a group equal in rank to 
Diplopoda. Scudder seems to have had too exclusive a regard to the 
Iulidce when considering the Diplopoda. The Order of Diplopoda, 
Packard thinks, ought to be divided into two suborders, the lower, more 
larval, and extinct group being the Archipolypoda, and the higher group 
being the genuine Chilognaths.

At Portland, in Oregon, Packard has found what he considers a Poly- 
desmus with eyes. It might be easily mistaken for a Trichopetalum. 
12-13 black ocelli are present. He proposes to name it Polydesmus ocel- 
latus. This species seems to be really a species of Chordeuma.

These are distinct in L. carinatum , Brandt ; in L. illyricum, Latzel, 
they are indistinct. In the cave-inhabiting Pseudotremia cavernarum , they 
seem to be obsolete, not being required as a means of self-defence.
