176 THE VOYAGE OF H.M.S. CHALLENGER. 



[Antipathes] lacerata, Lamk. 



Antipathes lacerata, Lamarck, Hist. nat. anim. sans vert., t. ii. p. 306 ; Milne-Edwards and 



Haime, Hist. nat. d. Coralliaires, t. i. p. 315 ; Dana, Zooph., p. 583. 

 Antipathes lacera, Lamouroux, Encyclop. method., p. 70 ; Polyp, flex., p. 377. 



Lamarck's description is very short : — " A. caule ramoso, spinis ecbinato, ramis 

 sarmentosis, tortuosis, sensim attenuatis ; ramulis lateralibus, tenuibus sublaceratis." 

 Habitat not ascertained, but Lamarck suggests that his specimen probably came from 

 the Indian Ocean. Other authors copy Lamarck's description, and Lamouroux adds that 

 the branches become intertwined as if for the purpose of support. 



[Antipathes] pectinata, Lamk. 



Antipathes pectinata, Lamarck, Hist. nat. anim. sans vert., t. ii. p. 306. 

 Hyalopathes pectinata, Milne-Edwards, Coralliaires, t. i. p. 323. 



"A. in piano ramosa, flabellata, ramis compressis, pinnato pectinatis ; ramulis 

 filiformi-subulatis, subdivisis; spinis raris " (Lamk., op. cit.). Lamarck gives no 

 locality. Milne-Edwards included this species in his genus Hyalopathes, characterised 

 by having a vitreous instead of a horny axis, though on what grounds I am unable to 

 say. The species has not been identified by subsequent investigators, and I am unable to 

 offer an opinion on it. 



[Antipathes] americana, Duch. and Mich. 



Antipathes americana, Duehassaing and Michelotti, Mem. Acad. Torino, ser. 2, t. xix. p. 332. 



" Simple, pinnee ; les ramuscules sont tres minces, et se dichotomisent assez souvent 

 tout en conservant les memes dimensions. Axe noiratre. Les ramuscules fibres et non 

 coalescent." The authors give no figure or further explanation. 



Habitat. — St. Thomas. 



[Ant ipathes] taxiformis, Duch. 



Antipathes taxiformis, Duehassaing, Rev. d. Zooph. et Spong. d. Antilles, p. 22. 



" Eamosa ; ramis sparse pinnulatis, ac inde taxiformibus ; pinnulis tenuissime (oculo 

 armato) echinulatis, nee nodoso-geniculatis." 



In further explanation Duehassaing adds that the species is small, and its ultimate 

 branches are disposed in a taxiform manner, the pinnules being scattered, and diminish- 

 ing in length from below upwards, so that each small branch resembles a yew tree in 

 miniature. 



Habitat. — Off Island of Desirade (Lesser Antilles), in over 100 metres.
