Eledone rotunda, Gunther & Dallas & Carruthers & Francis, 1885

Eledone rotunda , n. sp.

The Body is spheroidal, very little longer than broad, and the ventral groove is not marked. The mantle-opening ex ­ tends one third round the body, ending some distance directly below the eyes. The siphon is slightly tapering, and extends one third the distance to the umbrella-margin.

The Head is short, nearly as broad as the body, and the eyes are round and rather prominent.

The Arms are equal and about twice as long as the body • they are very stout, and taper gradually to blunt points; their section shows a triangle projecting inwards and a rounded surface looking outwards, the former much more prominent than the latter. The umbrella is wide, extending one third up the arms, a little further dorsally than ventrally. The suckers are comparatively small, closely set, and deeply cupped. There is no trace of a hectocotylus.

The Surface is perfectly smooth.

The Colour is dull purple, palest on the body and deepest on the inner surface of the umbrella.
