Navanax sp. #1
Maximum size:  30 mm.

Identification:  This species is superficially similar to Chelidonura fulvipunctata. However, its white patches are more diffuse, it lacks any sign of longitudinal lines and it lacks a central orange spot on the front of its head. It also reaches a larger size and has a more elongate internal shell with a larger protoconch and no brown tint at the apex.

Natural history:  Navanax sp. #1 is a rare species found in moderately exposed rocky habitats. It is known from tide pools and subtidally to 15 m (50 ft). It shows a nocturnal activity pattern when held in a dish and, unlike C. fulvipunctata, produces extensive defensive mucus when handled.

Distribution:  Maui and Lanai.

Taxonomic notes:  First recorded in Hawaii from Maliko Bay, Maui by PF on May 23, 1992.
