8. Bathymetrical range: 70 to 2900 fathoms. 
Greatest range of one species: Hymenaster pellucidus, 70 to 1539 fathoms 
(fide Danielssen and Koren). 
All the species excepting Hymenaster pellucidus are confined to the Abyssal 
zone. Five species, Hymenaster pergamentaceus, Hymenaster echinulatus, 
Hymenaster infernalis, Hymenaster geometricus, and Hymenaster gibory,, 
occur in depths greater than 2000 fathoms. Hymenaster infernalis extends 
to 2900 fathoms, the greatest depth at which Asterids were dredged. by the 
Challenger. 
y. Nature of the Sea-bottom: The majority of the species are found on Globigerina 
ooze, viz., Hymenaster nobilis, Hymenaster formosus, Hymenaster sacculatus, 
Hymenaster carnosus, Hymenaster vicarius, Hymenaster celatus, Hymenaster 
crucifer, Hymenaster porosissimus, Hymenaster graniferus, Hymenaster cocci- 
natus, and Hymenaster precoquis; the last is also found on Diatom ooze. 
Hymenaster latebrosus is found on Diatom ooze. fymenaster pergamentaceus, 
Hymenaster pullatus, and Hymenaster membranaceus frequent Blue mud. 
Hymenaster echinulatus, Hymenaster infernalis, and Hymenaster geometricus 
live on Red clay. Hymenaster glaucus is found on Green mud. Hymenaster 
anomalus on Pteropod ooze. Hymenaster pellucidus is found on Biloculina 
clay, sandy clay, and Blue clay. 
The species dredged by the Challenger are indicated in the above list by an asterisk.
