That record does not specify the number of colonies, but Fraser’s (1944a)description was of a single colony. No typesor other specimens were located elsewhere, including the Fraser Hydroid Collection at the RBCM. The MCZ specimen, apparently the holotypeby monotypy (ICZN Art. 73.1.2), is now missing from its bottle. The vial originally containing it was carefully checked twice during this study, but no hydroids of  H. eximiawere found.  Fraser (1944a)founded  Hebella eximiain his book on hydroids of the western North Atlantic. Nogonosome was present, and he was uncertain of its generic affinities. Boero et al. (1997)referred it to the synonymy of  H. scandens( Bale, 1888), given the resemblance of its trophosome to that species. Their conclusion has been upheld in the current WoRMS list. Based on Fraser’s account of the morphology of its hydrothecae, however, and the considerable depth from which it was collected, it may well be distinct. It is held here to be a species inquirenda. With the holotypenow missing, designation of a neotype, following provisions of the ICZN, seems desirable if the species is re-discovered. 1915525901 1879-01-27 USCSS A.
