Identification:  This is 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. Natural history:  Atagema cf. osseosa is a moderately rare species found in protected to moderately exposed rocky habitats at depths of < 1 m (< 3 ft). Distribution:  Big Island, Maui and Oahu: Atagema osseosa is widely distributed in the Indo-Pacific. Taxonomic notes:  This is 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 texture and dorsal crest appear to be somewhat different from the animals shown in the photos of Atagemma osseosa on the Sea Slug Forum. Photo:  CP: 21 mm: Hekili Point, Maui; Nov. 26, 2003.
