Abstract

A new species of Physophora, belonging to the physonect family of siphonophores Physophoridae is described. It can easily be distinguished from the only other recognised species in that family, P. hydrostatica, by the presence of two types of bracts. The arrangement of the palpons and bracts throws new light on the cormidial organisation of the physophorids, and comparisons are made between both species. The validity of an enigmatic physophorid species, Discolabe quadrigata, is discussed.
