Cephalopoda - Ammonitida - Arietitidae

TYPE SPECIES.-Canavarites discretus Hyatt, under Code Art. 70(b). Ammonites discretus was named by J. de C. Sowerby in de la Beche (1831, p. 320, fig. 63), the illustration being a crude woodcut which is not interpretable. This species was revised by Canavari (1882, p. 60. pl. 21, fig. 9a-c, 10a-d, 11a-c; 1888, p. 187, pl. 7, same figs.) and Hyatt, in setting up the genus Canavarites, cited the type species as "C. (Ariet.) discretum Canav. sp." Hyatt is therefore considered to have employed deliberate misidentification, as there is no means of knowing whether Canavari's interpretation of the species was the same as that of Sowerby. Canavari examined 14 specimens, some of which have been located at Pisa by Dr. G. Pinna.
