REPORT ON THE ALCYONARIA. 285 



Esper was not acquainted with their habitats, though he thought it probable they were 

 from the "East Indies;" Muricella complanata, Muvicella nitida, Verr., Muiicella 

 perramosa, Eid., have been found at Japan, the last named also occurring at the 

 Mauritius. Muricella flexuosa, Rid., occurs at Hong Kong, Muricella crassa, Muricella 

 umbracticoides (Std.), and Muricella tenera (Rid.), were dredged off Australia and 

 south of Papua, while Muricella gracilis occurs at the Admiralty Islands. 



Elasmogorgia, Wright and Studer. 



The only species known of this genus [Elasmogorgia filiformis) was found in the 

 Arafura Sea, south of Papua. 



Muricea, Verrill. 



The species of this genus, taking it in its restricted sense, seem to be widely 

 distributed in the tropical seas, being found at China and the East Indies; they 

 apparently abound on the Atlantic and Pacific shores of America, from whence very 

 numerous species have been described by Verrill ; one species, Muricea bicolor, was met 

 with by the Challenger in the Atlantic, at Bahia. 



Hypnogorgia, Duchassaing and Michelotti. 

 Hypnogorgia pendula, D. and M., is recorded from Guadeloupe. 



AntJiogorgia, VerriU, 

 Anthogorgia divaricata, Verr., is described as collected by Stimpson at Hong Kong. 



Menella, Gray. 



Menella indica, Gray, is recorded from "Bombay, Back Bay (Captain Thompson)." 

 If, as hinted in the Introduction (ante, p. liv), a species collected by Dr. Ddderlein at 

 Japan belongs to this genus, then the distribution would be thus far extended. 



Menacella, Gray. 

 The habitat for Menacella reticidaris, Gray, is not recorded.
