Dale R. Calder
I'm currently Curator Emeritus at the Royal Ontario Museum, Toronto, Canada, having taken early retirement in 2003. While retired, I continue to do research, mainly on taxonomy of hydrozoans.
My graduate training (both A.M. and Ph.D.) was in Biological Oceanography at the School of Marine Science of the College of William and Mary in Virginia (USA). After holding a National Research Council of Canada Postdoctoral Fellowship at the National Museum of Natural Sciences, National Museums of Canada in Ottawa (1968-1969), I returned to Virginia and to the Virginia Institute of Marine Science, Gloucester Point, for four years (1969-1973) as an Associate Marine Scientist. From 1973-1981 I was an Associate Marine Scientist at the Marine Resources Research Institute, South Carolina Wildlife and Marine Resources Department, in Charleston, South Carolina, USA. In 1981 I joined the staff of the Royal Ontario Museum (ROM) as Associate Curator-in-Charge of the Department of Invertebrate Zoology. In 1991 I was appointed a Research Associate of the Bermuda Aquarium, Museum, and Zoo, and from 2000 to 2006 I served as a Commissioner on the International Commission on Zoological Nomenclature. Most recently, I was appointed a Research Associate of the Royal British Columbia Museum (in 2016). Along the way, academic positions have been held at the College of William and Mary in Virginia (Assistant Professor of Marine Science, 1970-1973), the University of Virginia (Assistant Professor of Marine Science, 1971-1973), the College of Charleston (Adjunct Assistant Professor of Biology, 1974-1981), and the University of Toronto (Associate Professor of Zoology, 1983-2003).
Projects currently underway include: (1) a report on hydroids from Cocos Island, Costa Rica, with colleagues from the USA and Ecuador; (2) research on intertidal hydroids of Newfoundland and Labrador, Canada.
Supervisors: Dr. Morris L. Brehmer (College of William & Mary, Williamsburg, Virginia, USA; 1964--68, Dr. Marvin L. Wass (College of William & Mary, Williamsburg, Virginia, USA; 1964--68), and DR. J. Sherman Bleakney (Acadia University, Wolfville, Nova Scotia, Canada; 1963--64)

Hawaiian Islands. Of these, four are anthoathecates and 38 are leptothecates. Among the latter, Sertularella affinicostata
and Monotheca gibbosa are described as new species. The binomen Halopteris longibrachia is proposed as a new
replacement name for Plumularia polymorpha var. sibogae Billard, 1913, an invalid junior primary homonym of P.
sibogae Billard, 1911. Based largely on evidence from earlier molecular phylogenies, the genus Disertasia Neppi, 1917
is resurrected to accommodate species including Dynamena crisioides Lamouroux, 1824, Sertularia disticha Bosc, 1802,
and Sia. moluccana Pictet, 1893. Sertularella robusta Coughtrey, 1876 is an invalid junior primary homonym of Sla. gayi
var. robusta Allman, 1874a, and has been replaced here by the binomen Sla. quasiplana Trebilcock, 1928, originally
described as Sla. robusta var. quasiplana Trebilcock, 1928. Clytia hummelincki (Leloup, 1935) is referred to the synonymy
of its senior subjective synonym, C. brevithecata (Thornely, 1900). Following Reversal of Precedence provisions in
the International Code of Zoological Nomenclature to preserve prevailing usage of binomena, the familiar names Sia.
disticha Bosc, 1802 (also known as Dynamena disticha) and Lytocarpia phyteuma (Stechow, 1919b) are designated

and Aglaophenia clavicula Whitelegge, 1899, respectively, names now reduced to the status of nomena oblita. Twenty

the genus Tridentata Stechow, 1920. Hydroids of the NOWRAMP 2002 collection consisted largely of presumptive
widespread species, with over 75% of them having been reported elsewhere in the tropical Indo-west Pacific region.

Sertularia pourtalesi Nutting, 1904, a seldom-reported species, is assigned to Dynamena Lamouroux, 1812 and recognized as distinct from D. disticha (Bosc, 1802). Calyptospadix cerulea Clarke, 1882 and Bimeria franciscana Torrey, 1902 (also known as Garveia franciscana) are taken to be conspecific, with Calyptospadix Clarke, 1882 treated as a valid genus. Confusion over the identity of Lovenella gracilis Clarke, 1882 in literature on North American hydroids is addressed, and topotypic specimens from the Chesapeake Bay region are illustrated to document characters that distinguish the species. Campanularia colombiana
(Wedler, 1976) is reported for the first time outside the Caribbean coast of Colombia. The fauna studied here consists largely of species known to occur in the tropical and subtropical western Atlantic.
