Conus (Conospira) galensis (Noetling, 1901)

The shell is of small size, elongate and double conical in shape, composed of an elevated spire and a high, acuminated body whorl.

Embryonic whorls not preserved.

Only two and a half spire whorls are preserved, but they prove that the spire was elevated and composed of rather low whorls, which were very canaliculate on the upper side and set with fine granulations along the keel; as each succeeding whorl laves free a considerable part of the preceding one, the step-like profile line of the spire is more pronunced than in any of other species.

The body whorl is rather high, not very broad at its posterior end, accuminate anteriorly; a sharp keel divides a narrow, deeply canaliculate posterior portion, sloping towards the suture from a large anterior one, sloping towards the suture from a large anterior one, sloping in opposite direction.

The profile line is therefore represented by a sharp angle having a short deeply concave posterior and a large apparently slightly concave anterior side.

The surface is smooth, but there appear a few indistinctly visible revolving lines on the posterior portion, while the anterior one bears about 6—7 deeply engraved lines separated by broad flat interstices.

Striae of growth indistinct.
