THE ANTHOZOA 



nected by horizontal soleiiia or by lateral stolons or platforms contain- 

 ins: solenia. Skeleton either horny or calcareous ; when calcareous 

 spicular. 



Familt 1. CoRNCLARiiDAE. The zooids are united only by their 

 bases. Genera — Com u/anti, Lainarck. Without spicules. The stolons are 

 single solenia. The proximal parts of the zooids and stolons protected by 

 a horny sheath. Clandaria, Quoy and Gaim., spicular calcareous skeleton 

 present. Zooids free, borne on a membranous or retiform creeping stolon 

 which includes many anastomosing solenia. [Clavularia inridis, Quoy and 



Ku.. VIU.

 Syringoporoides, showinj; the lateral connect- 

 ing stolons. (After Uickson.)

Skeleton of a young colony of Tnbipora pur-

 stolon ; cv, corallites ; j>p, platfonus. (After

Gaimard, occurs in two varieties. The one variety has all the charactei-s of 

 the genus, but the second variety, described and figured by Hickson (44 and 

 45), difl'ei-s from all other members of the genus in that the zooitls are 

 connected at varying heights above the basal stolons by tubular con- 

 necting stolons containing solenia, and conse(piently it l>ears a close 

 resemblance to Syringopora (comp. Fig. VIII. with Fig. X. 7). The 

 character in question, if of constant occurrence, would warrant the 

 placing of C. viridis in a new genus allieil to the Syringo{xiridae and 

 Tubiporidae. As it is, the cliaracter must be reganled as accidental rather 

 than essential, but is of importance as indici\ting the atfinities of the last- 

 named families with the Cornulariiilae.] Sarcfxlictijoti, Forbes, like Clavu- 

 laria, but the zooids are wholly retractile within cushion-like thickenings 

 of their bases. Sympoiiium, Ehrb., the crustaceous stolon is thickened
