5Cf, THE VOYAGE OF H.M.S. CHALLENGER. 



Pacific fauna is therefore not certain. Asterias scaler, Asterias fragilis, 

 and Asterias mollis, from New Zealand. Asterias sinusoida, from 

 Tasmania. * Asterias (Stolasterias) gemmifera, from the Fij i Islands, 

 and extending to Chili. Asterias rodolphi, from the Kermadec Islands. 

 Passing to the northern area on the eastern side, Asterias epi- 

 chlora, Asterias janthina, and Asterias ochracea, from the Island of 

 Sitcha, the first extending to Paget Sound and the coast of Oregon, 

 and the last to San Francisco. Asterias vancouveri, from Vancouver 

 Island. Asterias conferta, Asterias hexactis, Asterias paucispina, 

 and Asterias troschelii, from Puget Sound. Asterias fissispina, 

 Asterias katherinte, and Asterias lilikeni, from the coast of Oregon. 

 Asterias sequalis, Asterias brevispina, Asterias capitata, Asterias 

 sertulifera, Asterias for reri, and Asterias exquisita, from the coast of 

 California. Asterias inermis and Asterias nautarum, from Ecuador. 

 Asterias gelatinosa, Asterias fulva, Asterias germaini, Asterias lurida, 

 Asterias mitis, Asterias spectabilis, * Asterias (Cosmasterias) sulci- 

 fera, Asterias varia, Asterias clavata, and Asterias fulgens, from 

 the coast of Chili. "" Asterias (Cosmasterias) tomidata, from the Gulf 

 of Penas. * Asterias cunninghami, off the coast of Patagonia, and 

 extending- through the Strait of Magellan into the Atlantic as far as 

 the Falkland Islands. Asterias brandti and Asterias neglecta, from 

 the Strait of Magellan. Asterias pliilippi has only the vague record 

 of South America as a locality, and it may not, therefore, be correctly 

 included in the Pacific fauna. 



/3. Bath if metrical range: Shallow water to 1250 fathoms. 



Greatest range of one species: Asterias contorta, 11 to 860 fathoms {fide 

 Perrier). 



The majority of the species are confined to the Littoral zone. Asterias 

 (Leptasterias) miilleri, Asterias (Cosmasterias) sulcifera, Asterias vulgaris, 

 Asterias panopla, Asterias contorta, Asterias fascicularis , Asterias gracilis, 

 Asterias tanneri, Asterias briareus, Asterias richardi, and Asterias (Stolas- 

 terias) stichantha, pass into the Continental zone. Asterias contorta, Asterias 

 gracilis, Asterias fragilis, Asterias vesicidosa, and Asterias {Hydr asterias) 

 opludion, occur in the Abyssal zone ; the last three being at present known only 

 from that zone. Asterias (Hi/drasterias) ophidion is the species attaining the 

 greatest depth, viz. 1250 fathoms. 



y. Nature of the Sea-bottom : The character of the habitat of the older known species 

 is recorded in comparatively few cases. The ground inhabited by the Littoral 

 species varies considerably. The following occurrences are recorded. On
