The logs are poor- ly preserved, about as long as the bi'eadih of the body (relatively longer in front) and apparently have very prominent coxae, as in other carboniferous ,*.

The single specimen probably represents nearly the whole animal, though neither end is shown; it is hardly probable that anything more than the head is wanting at the an- terior extremity, but posteriorly an indefinite number of segments. T'^cre are twenty- three segments in all. The first two behind the head arc slender and twice as long as broad, the third subquadrate, the four or five succeeding broader than long, of subequal length, but increasing breadth in passing backwuiil; thereafter they appear to be of the same size, about twice as broad as long and rectangular, the front outer angle sometimes a little produced. The first two elongated segments show a slight median carina; the fourth and succeeding ones on either side a laterodorsal series of large circular depres- sions next the anterior edge. Length of fragment, 46 mm.; breadth of first body segment, 1 mm.; of seventh, 5 mm.; length of legs, 3 mm. Mazon Creek. Mr. R. D. Lacoe^ N^o. 1821ab. Ilyodes gen. nov.
