a firm, cream species. The notum has an intricate network of
papillae surrounding shallow depressions and there is a dorsal crest
that rises to a point in its center. Lobes of the crest bracket the
branchia and the rhinophore sheaths are high. The papillae are
flecked with white and the rhinophores with brown.
Atagema cf. osseosa is a moderately rare
species found in protected to moderately exposed rocky habitats at
depths of < 1 m (< 3 ft).

the species that Kay, 1979 lists as Trippa
osseosa. Although Kay, 1979
suggests that it was first reported from Hawaii in Pease, 1860 as Doris excavata, it seems more
likely that that name refers to Sclerodoris sp. #1. Its
dorsal crest appear to be somewhat different from the animals shown in
the photos of Atagemma osseosa
