Julia sp. 2 is the least commonly seen of the the Hawaiian species of Julia. It has a maximum shell length of 3.7 mm. I know of only a few live animals. All were in rocky habitats at over 4.5 m suggesting that it may be restricted to somewhat deeper water than the other Hawaiian Julia spp. The color is consistent with the light green shell covered by a fine, darker green reticulation. There is no brown pigment with the exception of a small amount of "stain" ventral to the hinge in some specimens. In live animals, the body is densely covered with cream flecks and cream flecks form basal, medial and terminal bands on the rhinophores. The hinge is very large and the central, tooth-like knob has a prominent, "C-shaped" apical depression.
