Abstract
In the present paper I have communicated some observations on the Myriapoda, on Petrobius , and on certain Arachnida. Among the former I have examined species belonging to the genera Glomeris , Iulus , Polydesmus , Lithobius , Cryptops , Geophilus , and Arthronomalus . Through the labours of Brandt, Fabre, Newport, Stein, Treviranus, and other eminent naturalists, we are tolerably well acquainted with the anatomy of the generative organs in the Myriapods; but these observers have occupied themselves principally with the arrangement and forms of the organs, and have not paid much attention to the different stages of egg-development, nor to the relation in which the young egg stands to the surrounding tissues. This relation is indeed very curious, and seems to have been generally misunderstood.
