Note 152 — ORDER II.—ABDOMINALIA.
Reading edition
As I have given, in my former volume on the Lepadidæ, p. 286, so many measurements of the antennæ, I may here add those of Cryptophialus,—the length from the end of the disc to the end of the second segment, (formerly called by me, erroneously, the basal,) is 26/6000ths of an inch; the greatest width of the second segment, 9/6000ths; the length of the little ultimate segment, 3/6000ths, and its width under 3/20000ths of an inch.
