The affinities with Limtdus, according to the views of other authorities, justify the association of Trilobites and Arach- noids. A compromise may be perhaps effected by regarding the Trilo- bites as an offshoot from a stock ancestral to. Fig , 146.—Vertical cross-section of a Trilobite (Calymene).—After Walcott.

On the ventral surface of the thorax there are five pairs of gills covered by flat plates, of which the most anterior pair are very large, and form the so-called operculum (cf. Limulus). The surface of the body was covered with scales. Some of the Eurypterids reached a length of 6 ft. This order is sometimes placed near the Crustacea, but the general opinion seems to be that which links them through Limulus to Arachnoids. Order 3. Trilobita. Trilobite
