Mr. A. G. Butler on Eastern Lepidoptera. 317 
indications or remains of the strongly marked tegumentary 
ornamentation of the more ancient Pemphix and G'lyphea. 
The entire body of Areosternus is covered with little tufts 
of yellow hairs, with here and there isolated longer hairs 
scattered among the tufts. The fossil Glyphee present no 
hairs. It might be supposed that the tubercles of the surface 
of the carapace of these latter Crustacea were peduncles which 
at one time bore tufts of hairs, and that these hairs were lost 
during fossilization. There are, however, Crustaceans which 
lived in the same ages and in the same waters, side by side 
with the Glyphee, such as the Megachirt, the Microchiri, 
and others, the remains of which, preserved in the Litho- 
graphic Limestone of Bavaria, still allow us to perceive a 
multitude of hairs, which are very visible along the antenne, 
the anterior limbs, &c. of these animals. Why, if the 
Glyphec were ornamented with hairs, should not their fossil 
remains show us hairs, preserved as perfectly as those of their 
contemporaries the Megachiri? We may therefore suppose 
that the Glyphee were not furnished with hairs like Arao- 
sternus. But no one will assert that an animal the skin of which 
is covered with hairs, cannot descend from another of which 
the skin is naked, or that a hairy animal could not have had 
an ancestor with a skin unfurnished with hairs. ‘The elephant 
of the present day is completely destitute of hairs, while its 
ancestor, the mammoth, was provided with them; but no 
one doubts as to the degree of relationship which unites these 
twoforms. No one will see a generic difference in the more 
or less hairy state of the outer integument of animals. 
The limits of our investigation do not allow us to dwell 
further upon these interesting subjects. What we have said 
will suffice, we believe, to demonstrate that the genus Glyphea 
existed as long ago as the Trias under the form of Pemphia, 
and that it will probably become extinct in the present epoch 
under the form of Arcosternus.
