Edwards, H. Milne. — Histoire naturelle des Coralliaires, ou polypes 

 proprement dits. Vol. iii. 8vo. Paris. Plain, 8s ; col. 10s 6d 

 A complete monograph of the Zoantharia, Bugosa and Alcyo- 

 naria. All the species and genera of these groups known to the 

 author are fully described. There is a general introduction on 

 the organization of the Polypes. These form the class Coralliaria, 

 divided into the sub-classes Cnidaria and Podactinaria. The 

 Cnidaria include two orders, Alcyonaria and Zoantharia. Of 

 Alcyonaria are distinguished three families, Alcyonidcd, Gorgo- 

 nidce, and Pennatulidce. In this order Prof. Milne Edwards 

 establishes a new genus, Haimeia, in honour of his recently 

 deceased colleague. The single species, IL.funebris, has a fur- 

 ther interest in being the only recorded example of a solitary 

 Alcyonarian. The Zoantharia are arranged under three sub- 

 orders : Malacodermata, Sclerobasica, and Sclerodermata. All 

 the Malacodermata are divided into two families, the Actiniadce, 

 with tentacles alternate, and the Cerianthiidce, having two rows 

 of opposite tentacula. This portion of the work is, perhaps, the 

 least perfect in its systematic details. Of Sclerobasica there is 

 but one family, Antipathidce. The numerous families of Sclero- 

 dermata fall under five principal sections : Aporosa, Perforata, 

 Tubulosa, Tabulata, and Rugosa. The sub-class Podactinaria is 

 equivalent to the family Lucernariadae of other authors. 



A short chapter is added on the geographical distribution of 

 the Polypes. 



There are, also, three fasciculi of Plates, representing some of 

 the forms described in the text.
