Abstract
American Journal of Science, April.—The morphology of Triarthrus, by C. E. Beecher. Most of the recent advances in the knowledge of trilobite structure have come from the study of Triarthrus. Much time was spent by the author in carefully working out the numerous specimens from the abundant material in the Yale Museum. Altogether upwards of five húndred individuals with appendages more or less complete have been investigated; and at the present time all the important exoskeletal features have been seen and described.
