I have not encumbered this list with bibliographical references; they will be found in my 
“Catalogue of Recent Cephalopoda” and its “First” and “Second Supplements” (Proc. Boy. Phys. Soc. 
Edinburgh , vol. 9, pp. 205—267, 1886; vol. 13, pp. 363—373, 1897; vol. 17, pp. 254—299, 1909). 
30 Two species were referred by the author to this genus, but as these are now both regarded by him as Syno¬ 
nyms of different species of Teleoteuthis the genus lapses and it is hardly necessary to determine which was the type. 
31 Teleoteuthis Verrill was proposed as a substitute for Onychia Lesueur, which was preoccupied, and therefore 
takes the same type as that genus (0. caribbaea).
