trilobite 
semblino; the tlioracic segments, and with an axial raised 
portion, hut united together. Of the under surface of a 
trilobite almost nothing was known until recently, and 
much still remains to be accurately determined. A well- 
developed lip-plate or hypostome had been recognized, 
but nothing further was known until 1870, when the un- 
der side of a species of AsaphiiR, showing indistinct appen- 
dages, was described by Killings. Other investigators have 
pursued this subject, by .means of sections of fossils, with 
the result of showing the presence of articulated appen- 
dages, or legs, and of other organs regarded as gills. The 
embryology of trilobites, so far as known, agrees most 
nearly with what has been accurately determined in the 
case of the horseshoe-crab. What may be inferred of the 
mode of life of trilobites is that probably their habits were 
like those of these crabs. Dudley trilobite, a common
