Skandaalso called Kumara (the youth), Karttikeya, or Subrahmanya (in the south) - the six-headed war-lord of the gods; and Ganese, the lord (or leader) of Siva's troupes of attendants, being at the same time the elephant-headed, paunch-bellied god of wisdom; whilst a third, Kama (Kamadeva) or Kandarpa, the god of love, gets his popular epithet of Ananga," the bodiless,"from his having once, in frolicsome play, tried the power of his arrows upon Siva, whilst engaged in austere practices, when a single glance from the third (forehead) eye of the angry god reduced the mischievous urchin to ashes.
1 The EXevoSep,ua, or "urchin-skinned" animals, have long been a favourite subject of study with the collectors of sea-animals or of fossils, since the lime deposited in their skins forms hard tests or shells readily preserved in the cabinet.
Johns Hopkins I Sometimes called "Echinodermata," a Greek name meaning "sea-urchin-skins," which was invented by J.
- Supposed calycinal systems of free-moving Echinoderms. A, regular sea-urchin (Cidaris); B, sea-urchin with a suranal plate (Salenia); C, developing ophiurid (Amphiura); D, young starfish (Zoroaster).
Accepting the homology of these apical systems with the calycinal system, the theory would regard the aboral pole of a sea-urchin or starfish as corresponding in everything, except its relations to the sea-floor, with the aboral pole of a fixed echinoderm.
Neumayr adduced the Triassic sea-urchin Tiarechinus, in which the apical system forms half of the test, as an argument for the origin of Echinoidea from an ancestor in which the apical system was of great importance; but a genus appearing so late in time, in an isolated sea, under conditions that dwarfed the other echinoid dwellers therein, cannot seriously be thought to elucidate the origin of pre-Silurian Echinoidea, and the recent discovery of an intermediate form suggests that we have here nothing but degenerate descendants of a well-known Palaeozoic family (Lepidocentridae).
The echinoids or sea-archins (see SEA-Urchin) may be grouped under the following orders, here named in the sequence of their appearance in the rocks.
