Reexamination of monstrilloid copepods collected during the Siboga Expedition (1899-1900) and deposited in the Zoological Museum (Amsterdam) has yielded the opportunity of redescribing some of these species according to upgraded standards. The only two species of Cymbasoma ( C. gigas A. SCOTT and C. bullatum A. SCOTT) collected in this expedition are redescribed in detail from the type (syntypic) specimens. The former species, which is the largest monstrilloid known, has several interesting characters including the relative length of the antennules, the ornamentation of the head, and the peculiar spines on the first exopodal segment of legs 1-4. The other one (C. bullatum) shows unique characters such as the basal swelling of the caudal setae, the ornamentation of the head with a pair of horn-like processes, and peculiar details of the antennular armament. Both species are compared with related forms for the first time; lectotype and paralectotype specimens are also designated herein.
