Vernonella Sond. is restored as a distinct genus from synonymy under Vernonia and Centrapalus. Included are the type species Vernonella africana and 10 additional species with thinly scarious-margined involucral bracts and distinctive small, short-colpate type A pollen.

The accepted type locality of the Whiskered Auklet Aethia pygmaea, St. Matthew Island, is considered to be erroneous because it lies far outside of the bird's geographic range. The species was founded on the description of a now-lost immature specimen taken on the third voyage of James Cook, and the locality was probably a misattribution due to a simple transcription error. We here designate as revised type locality ‘Unalaska Island, Aleutian Islands, Alaska,’ a place known to have been visited on Cook's third voyage where and at a time when immature birds would have been present.

Lebbeus carinatus de Saint Laurent, 1984, is a junior homonym of L. carinatus Zarenkov, 1976. Both are deep-sea Pacific species, differing in the dorsal carina of the carapace and epipods of the pereopods. I provide a replacement name for L. carinatus de Saint Laurent, illustrations, and a more complete description.

Bryocamptus (Echinocamptus) cheongokensis sp. nov. is a harpacticoid copepod of the family Canthocamptidae that was collected from a pool in Cheongok cave, Donghae-shi, Kangwon-do, Korea. The new species is characterized by the following diagnostic characters: 1) an eight-segmented female antennule, 2) the absence of an inner seta on the second exopodal segment of P1, 3) the distal segments of the exopod of P2 to P4 are as long as the other two segments combined, and 4) there are six setae on the basoendopod of the female P5. This species has a slight resemblance to the “hiemalis” group. However, the new species is clearly distinguishable from the species in the “hiemalis” group by the combination of ornamentation of the free margin of the operculum, the number of setae on the P4 endopod, the length/width ratio of the P5 exopod in the female, and the number of setae on the first endopod segment and the lengths of each apical seta on the last endopod segment of P3 in the male. Thus far, 22 species have been reported in the subgenus Echinocamptus, and the “hiemalis” group includes ten species. Species in this group are typically found in the interstitial groundwater around springs, lakes, streams, and caves. The new species described herein is the first described member of the subgenus Echinocamptus from caves in Korea.

Three new species of Polychaeta (Annelida) are described from a benthic infaunal collection made in a seagrass bed dominated by Syringodium filiforme, manatee grass, at 8–9 m depth, in Bermuda: one species of Caulleriella (Cirratulidae), one of Schistomeringos (Dorvilleidae) and one of Exogone (subfamily Exogoninae, Syllidae). The syllid is briefly described here but not named because the only two specimens have been misplaced. The new cirratulid has a short prostomium with a novel arrangement of bifid hooks in both neuro- and notopodia, the new dorvilleid has furcate setae with subequal tynes in all setigers, and the new syllid has a novel arrangement of the simple setae. The polychaete diversity of Bermuda was considered to be relatively well studied, with a low diversity compared to similar subtropical locations and with a low degree of endemism compared to other oceanic islands. Identification of these three new species from the seagrass rhizosphere, in combination with recognition of other unidentified and misidentified species from the same collection, show instead that polychaete diversity in Bermuda is notably higher than recently reported and includes several species not reported from other geographic locations. Seagrass bed infaunal diversity is especially poorly documented.

A new species of antipatharian coral (Anthozoa: Antipatharia) is described from the Pacific coast of Costa Rica. Lillipathes ritamariae, new species, forms large, multi-branched, flabellate colonies that reach a height of 60 cm or more. The genus Lillipathes is characterized by pinnules in four rows and arranged in bilateral alternating pairs. In L. ritamariae, the pinnules occur in only two rows in portions of the corallum; however, the characteristic Lillipathes pinnulation pattern is common enough to support assigning this species to this genus. The species can be distinguished from its cogeners by its very short pinnules (mostly 1–1.5 cm in length) and the development of many of the lateral pinnules into pinnulated branches. In contrast, in L. wingi, the pinnules are up to 5 cm long and only a few in the colony develop into branches. In L. quadribrachiata, the pinnules are up to about 3 cm long, and in Lillipathes lilliei, the pinnules are more than 10 cm in length, and only a small number develop into branches.

A specimen of the genus Tretodictyum Schulze was found among the collections made by Harbor Branch Oceanographic Institute, Ltd., in their 1986 excursion to Cocos Island, tropical eastern Pacific Ocean. No member of that genus is known from the region. The specimen differs in many characters from the five known members of Tretodictyum and is described here as a new species, T. cocosensis.
