Grygier,-M.J. Larval and juvenile Ascothoracida (Crustacea) from the plankton. PUBL.-SETO-MAR.-BIOL.-LAB. 1988. vol. 33, no. 4-6, pp. 163-172. Two kinds of previously recorded ascothoracid larvae from plankton over coral reefs in Hawaii and the Virgin Islands are redescribed as possible representatives of the Lauridae and Petrarcidae, respectively. A bathyal, tropical Atlantic ascothoracid larva from an epibenthic sled sample cannot confidently be identified to family. A planktonic, juvenile ascothoracidan from the eastern Indian Ocean belongs to the genus Synagoga.
