A full description of this, the only known species of Savagliiche, has been given from 

 the researches of Lacaze Duthiers at p. 51, and, as the definitions of both family and 

 genus rest on a single species, these need not be repeated. 



Habitat. — Mediterranean. Near African shores (Lacaze Duthiers), Adriatic (Nardo, 

 Heller). 



Family Antipathidj, Verrill, emend. 



Antipatharia in which the individual zooids have typically six simple tentacles. In 

 dimorphic genera three individuals, each with two tentacles, represent morphologically a 

 single six-tentacled zooid of the ordinary type. Sphincter muscle not developed ; 

 the tentacles are therefore only contractile and cannot be enclosed by the margin of the 

 peristome. There are always three pairs of well-developed primary mesenteries, one 

 pair of which occupies the transverse axis and bears the reproductive organs. There are 

 usually two or three other secondary pairs of mesenteries present which rarely extend 

 below the oral cone, and never bear mesenterial filaments. Sclerenchyma chitinous, 

 rarely forming a parasitic growth, and always bearing spines on the newer branches. 

 Usually these are present on all parts of the corallum. Ccenenchyma not traversed by 

 numerous canals, as in the Savagliidse, but, instead, the individual zooids are usually- 

 brought into communication by stolon-like outgrowths of their ccelentera. 



The sclerenchyma consists of thin, concentric, horny layers around a central lumen, 

 and always bears a number of spines on its surface which are usually recognisable on all 

 parts of the skeleton, but, in some cases, they may be confined to the more slender 

 portion of the corallum. 



This family corresponds closely with the genus Antipatlies as defined by Pallas. 



Subfamily Antipathin^e, Brook. 



Antipathidse the zooids of which are of the simple type with six tentacles, all springing 

 from the peristome, or two, in the sagittal axis, may be inserted at a lower level. Zooids
