Cyphaspis intermedia Weller, Metapolichas ferrist Weller, and a new species of 
Ostracoda, Leperditia illincisensis—shell differing from Leperditia faba, in being

strata of I[hnois.

The author describes Lepidocoleus Illinoisensis n. sp. a barnacle from the Clear Creek 
of Union County Oriskany chert and a new trilobite Dalmanites palaceus. This shovel

three-lobed process.
