32 Anatomy of Sagartia Scliilleriana [No. 1, 



The presence of solid scleroid particles of two kinds, as they will 

 be described in the present species, may likely be added to the generic 

 characters of this genus, but this has to be proved by the examination 

 of other species. 



Species. Sagartia Schilleriana, Stoliczlca, 1868. 

 Plates X and XI. 



Char. Sagartia corpore pulposo, transpa rente, virescente p >a ^^°i 

 basi lata, scepissime rotundata adlierente ; columna cylindracea, in 

 altitudine diamatro basis fere cequante, longitudinaliter angustatim sul- 

 cata, transversaliter minutissime corrugata ; septis ad peripheriam 

 plerumque 48, distinctis, ceqidistantibus, alternatim virescentibus ; ten- 

 taculis numeros is, pr ope peripheriam disci sitis, exterioribus brevissimis, 

 inter ioribus gradatim longioribus, omninis ad basin infatis, versus 

 apicem attenuatis, terminationibus subtruncatis et perforatis instructis ; 

 tentaculis seriem primam formantibus senis ceteris conspicue crassiori- 

 bus, ad basin sospissime rubescentibus, ad terminationes albidis ; apertura 

 transversaliter ovata, angusta ; labio plus minusve prominente, ad 

 marginem undulato, sub-reflexo, tuberculis duodenis instructo ; lenti- 

 ginibus bipartitis, ad utrumque angulum gonidialem sitis, tuberculis 

 ceteris minor ibus ; canalibus gonidialibus parvis, orificiis rotundatis, 

 vice prominulis, albide marginatis notatis ; radiis gonidialibus vix 

 dignoscendis ; gula sulcis virescentibus f areata. 



Ovariis duodenis, bipartitis, folliculis in utroque latere septorum 

 sitis, ctfruleo-purpurescentibus ; craspedis numerosis, sordide luteolis, in- 

 terne supra ovaria suspensis ; acontjis albis,perlongis ; cinclidibus sub- 

 rotundatis, numerosis, paululum impressis, in tegumine irregulariter 

 dispersis, nonnullis prope marginem superiorem columnce positis latis- 

 simis, semper apertis, ceteris minoribus aliquantisper obscuris ; en id is 

 ovato-elongatis, stiliformibus,* ectliorceis brevibas prope rectis instruc- 

 tis ; septis mesenterialibns intus ad basin solidulis, albis ; tegumine 

 corporibus minutis tabulatis siliceis, ac alteris subcylindraceis et varie 

 dentatis calcareis instructis. 



# Gossein his above quoted Treatise on the British. Sea- Anemones distinguishes 

 four kinds of cnidce, all of which have rather long, spirally coiled ecthorcea, except 

 one globular kind, in which no ecthorseum was observable. The cnidce of the 

 present species of Sagartia are mostly, short, straight, or very rarely slightly 

 bent. I shall term this kind of cnidaz which were also observed formerly by 

 Blainville, Leukart, and others, stiliform. Gosse says that the chambered form 

 is the usual one in the Actiniidce, though the present variation seems quite as 

 common.
