32 Anatomy of Sagartia Seliilleriana [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, Stoliczka, 1868. 

 Plates X and XI. 



Char. Sagartia corpore pulposo, transparente, virescente pallido, 

 hasi lata, scepissime rotundata adherente ; colnmna cylindracea, in 

 altiiudine diamatro basis fere aquante, longitudinaliter angustatim sul- 

 cata, transversaliter minutissime corrugata ; septis ad peripheriain 

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

 taculis numerosis, prope peripheriam disci sitis, exterioribus brevissimis, 

 interioribus gradatim longioribus, omninis ad basin infatis, versus 

 apicem attenuatis, terniinationibus subtruncatis et perforatis instruct is ; 

 tentaculis seriem primam formantibus senis ceteris conspicue crassiori- 

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

 transversaliter ovata, angusta ; labio phis minusve prominente, ad 

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

 ginibus bipartitis, ad utrumque angulum gonidialem sitis, tuberculis 

 ceteris minoribus ; canalibus gonidialibus parvis, orifciis rotundatis, 

 vix prominulis, albide marginatis notatis ; radiis gonidialibus vix 

 dignoscendis ; gula sulcis virescentibus f areata. 



Ovariis duodenis, bipartitis, folliculis in utroque latere septorum 

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

 terne supra ovaria suspensis ; acontiisalbis,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 ; cnidis 

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

 ts ; septis mesenterialibus intus ad basin solidulis, albis ; tegumine 

 corporibus minutis tabulatis siliceis, ac alteris subcylindraceis et varie 

 dentatis calcareis instructis. 



* Gosse in his above quoted Treatise on the British Sea- Anemones distinguishes 

 four kinds of cnidce, all of which have rather long, spirally coiled ectlwrcea, 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 cnidce which were also observed formerly by 

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

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

 common.
