REPORT ON ZOOLOGY, MDCCCXLIV.

Antennularia arborescens, Alcyonidium glomeratum, and Far-cimia spathulosa. Forbes (Annals, &c., xii, 1843, p. 40)rejects the genus Echinocorium, instituted by Hassall, tbenew Polype being nothing else than Alcyonidium echi-natum , to which several individuals of Coryne squamata hadaccidentally become affixed. Hassall (ib. xii, p. 117) took„ this objection very ill, without relinquishing his previousopinion. Forbes (ib. xii, p. 188), who subsequently recog-nised this Coryne as a distinct species, named it CoryneHassalli (corpore elongato, capite clavato, tentaculis brevibusalbidis), which might probably appease Hassall.

As Irish Zoophytes, the following Polypes have beennoticed by Thompson (ib. xiii, p. 440) : Thujaria Thuja,Zoanthus Couchii, and Lepralia verrucosa. According toForbes’s observations (Report of British Association, 1843,p. 146), but very few Zoophytes of the class of Polypes occurin the Egean Sea. Corallium rubrum is found there onlyin small specimens, as well as Farcimia fistulosa, Cladoceracmspitosa, and Porites dcedalea. Flustrae are rare, whilstAlcyonia are not so ; moreover, Forbes remarked in thatsea Edwardsia vestita, and two species of Pennatula, and insoundings, Idmonea, Caryophyllia, Plumuluria, Hornera, be-sides Myriapora truncata, Tubularia serpens, Retepora, Alecto,Eudendrium, Valkeria, Campanularia, Crisia, Actinia, andAlcyonium.

Various plants which, on account of their calcareous con-stituents, have been referred to the Polypes, viz., Corallina andthe allied genera, Galaxaura, Halimedia, Udotea, Acetabu-lum, Melobesia, Jania, &c., have been described as Algae byKiitzing (Anatomie, Physiologie , und Systemkunde derTange, 1843, p. 8), and it is there left undetermined whetherthe Sponges are of an animal or vegetable nature.
