CIDE DICTIONARY

scutibranchiata, n. pl. [NL. See Scutum, and Branchia.].

An order of gastropod Mollusca having a heart with two auricles and one ventricle. The shell may be either spiral or shieldlike. [1913 Webster]

" It is now usually regarded as including only the Rhipidoglossa and the Docoglossa. When originally established, it included a heterogenous group of mollusks having shieldlike shells, such as Haliotis, Fissurella, Carinaria, etc." [1913 Webster]
