[2] Mr. Bond has made a laughable error in his description. Like all of the coleoptera, the Mercurians were hexapoda (six legged). What Mr. Bond continually refers to in his narrative as "upper arms" were really the antenna of the insects which split at the end into four flexible appendages resembling fingers. His mistake is a natural one, for the Mercurians used their antenna as extra arms.—James S. Carpenter.
