540 REPORT ON ZOOLOGY, MDCCCXLIV. 



Antennularia arborescens, Alcyonidium yloineratum, and Far- 

 cimia spatlmlosa. Forbes (Annals, &c., xii, 1843, p. 40) 

 rejects the genus Echinocorium, instituted by Hassall, the 

 new Polype being nothing else than Alcyonidium echi- 

 natum, to which several individuals of Coryne squamata had 

 accidentally become affixed. Hassall (ib. xii, p. 117) took 

 this objection very ill, without relinquishing his previous 

 opinion. Forbes (ib. xii, p. 188), who subsequently recog- 

 nised this Coryne as a distinct species, named it Coryne 

 Hassalli (corpore elongate, capite clavato, tentaculis brevibus 

 albidis), which might probably appease Hassall. 



As Irish Zoophytes, the following Polypes have been 

 noticed by Thompson (ib. xiii, p. 440) : Thujaria Thuja, 

 Zoanthus Couchii, and Lepralia verrucosa. According to 

 Forbes's observations (Report of British Association, 1843, 

 p. 146), but very few Zoophytes of the class of Polypes occur 

 in the Egean Sea. Corallium rubrum is found there only 

 in small specimens, as well as Farcimia fistulosa, Cladocera 

 ccKspitosa, and Porites daedalea. Flustrse are rare, whilst 

 Alcyonia are not so ; moreover, Forbes remarked in that 

 sea Edwardsia vestita, and two species of Pennatula, and in 

 soundings, Idmonea, Caryopltyllia, Plumularia, Homer a, be- 

 sides Myriapora truncata, Tubularia serpens, Retepora, Alecto, 

 Eudendrium, Valkeria, Campanularia, Crisia, Actinia, and 

 Alcyonium. 



Various plants which, on account of their calcareous con- 

 stituents, have been referred to the Polypes, viz., Corallina and 

 the allied genera, Galaxaura, Halimedia, Udotca, Acetabu- 

 luni, Melobesia, Jania, &c., have been described as Algae by 

 Kiitzmg (Anatomic, Physiologic, und Systemkunde der 

 Tange, 1843, p. 8), and it is there left undetermined whether 

 the Sponges are of an animal or vegetable nature.
