Annandaleum Newman & Ross, 1971
SUMMARY
Sexes separate, capitulum of female with 14 partially calcified plates; tergum forming inverted V-shape; scutum with relatively long apico-lateral arm, about 1/4-1/2 length of tergal margin, basal margin entire; upper latus pentagonal to triangular, with or without additional arm or arms; carinal latus as high as wide, umbo at basi-carinal angle; inframedian latus higher than wide, vase-shaped, umbo submedial or basal; rostral latus wider than high; caudal appendage long, with 5-11 segments.
Type species: Scalpellum subflavum Annandale, 1906.
Composition: 6 species.
Distribution: worldwide. Known depth range 794 to 6810 m.
Remarks. Zevina (1978b) subsequently designated Scalpellum japonicum Hoek, 1883 as the type species of Annadaleum, but Newman & Ross (1971) had already designated S. subflavum as type. Their designation takes priority. However, some later authors such as Young (2007) have followed Zevina's designation.
