G-osse, P. H. — Actinologia Britannica : a History of the British Sea 

 Anemones and Corals. 



The recent British Actinoida (==■ Zoantharia s. Heliantlwida) 

 are here minutely described, and illustrated by numerous coloured 

 figures. The author distinguishes seventy-five species, and adds 

 definitions of the principal varieties of each. All the species 

 receive English names. A tendency is shown to multiply un- 

 duly the number of genera and families. A detailed account is 

 given of the anatomy of the Actinia?, which contains some new 

 facts, especially with regard to their stinging apparatus. The 

 most valuable part of the work is that which treats systematically 

 of the non-adherent forms. Under the name of ■ conchula' a 

 curious organ is described, which appears to be a modification of 

 the oral extremity of the single gonidial groove in some of these 

 creatures. 



A table is appended, showing the distribution of the species, 

 so far, at least, as at present known, around the different parts of 

 our coast. 



Gray, J. E. — Eevision of the Eamily Pennatulidae, with Descriptions 

 of some new species in the British Museum. With figures. 

 A. N. H. 3 ser. v. p. 20. Jan. 1860. 



Dr. Gray divides this family into five tribes: Fimiculineae 

 (Junciformes), Pennatiolece (Penniformes), Kopliobelemnoniece 

 (Claviformes), Veretillece (Yeretilloids), and Benillece. The 

 memoir of Herklats (Bidj. t. d. Dierkunde, part vij. 1858) is made 

 " the basis of this communication." Two plates are added, repre- 

 senting Sarcoptilus simosus, S. Gurneyi ; Sarcobelemnon Austral- 

 asia, and Renilla sinuata. 



. . On the G-enus Hyalonema. A. N. H. 3 ser. v. p. 229. 



Dr. Gray, following Brandt, regards Hyalonema as a Zoan- 

 tharian, and not, as he first supposed, a genus allied to Gorgonia. 

 He believes that the living Hyalonema finds its proper habitat 

 in a peculiar kind of Sponge, within the substance of which one 

 end of the coral is firmly embedded. He thinks also that the 

 two species of Hyalonema, and one of Hyalocliceta, described by 

 Brandt, may, possibly, be varieties of the same form. 



Notice of some new Corals from Madeira, discovered by 



J. Y. Johnson, Esq. Ann. N. H. 3 ser. vi. p. 311. 



These Corals are : Corallium Johisonii, allied to O. rubrum ; 

 Antipatlies gracilis, a fan-like branching species, about six inches 

 high ; and A. setacea, which has a straight elongate corallum, 

 covered with numerous short conical spinules. Its length is 18 

 inches. A variety of this last (j3. occiden talis), which may prove 

 a distinct species, has also been received from Turk's Island,
