STRUTHIOLARlIDiE. 
Struthiolaria mirahilis (Smith) = costulata (Martens) ; radula dif- 
ferent from that of all other Tmnioglossa in having 4 marginal teeth on 
each side instead of 2, so that each series of the radula contains 13 teeth 
instead of 7. G. Schacko, JB. mal. Ges. iii. pp. 317-323, pi. xi, [The 
radula of the typical species of Struthiolaria from New Zealand is as yet 
unknown ; it will be very interesting to know whether it agrees with 
that of the Kerguelen species ; if not, the latter must become a new 
genus.] The synonymy of the known species, which has been much 
confused by Reeve, is corrected by Paulucci, Bull. mal. Ital. (2) ii. 
pp. 223-232.
