Schizellozoon dentatum Calvet, 1931: 107 , pl. II, fig. 16.

Material examined

Holotype

AÇORES • 1 fragment; 38º27′ N, 28º03′25″ W; 523 m deep; on rock; scientific survey from 1895 by Prince Albert I from Monaco exped., st. 597, 23 Jul. 1895; MOM INV-22494-42 0559.

Remarks

This species has never been found again after its description. Calvet (1931) remarked the similarities of S. dentata with S. solanderia , pointing to the distinctive backed zooids and the presence of two avicularia on each autozooid ( Fig. 6A ). We examined the type specimen housed at the MOM that, unfortunately, is badly damaged and does not allow a detailed description or measurements ( Fig. 6B ). There is no further available material for this species. The lack of some features in the described type specimen, which are diagnostic of the genus (i.e., complete ovicell) makes the ascription of this species to Schizoretepora uncertain.
