TitleUnpublished manuscript, 'Observations on the anatomy of the antennae in a small species of crustacean' by John Denis MacDonald
DateDecember 1852
DescriptionMacdonald shares observations on a small crustacean which was found in considerable numbers in the voyage from St Vincent to Rio de Janeiro. There are several anatomical peculiarities mentioned, but Macdonald suggests the most remarkable is the structure of the right antenna of the male. These organs are in the female perfectly symmetrical, and resemble that of the left side in the male; and although in the very young state of the latter sex the right antenna differs but little in external appearance from the left, yet the peculiar hypertrophied condition of the modified segments in the corresponding organ of the adult male is to be distinctly traced in a rudimentary state.

Includes two pages of figures of the antennae in coloured ink.

Subject: Zoology / Carcinology

Written by MacDonald aboard H M S Torch, Simon's Bay [South Africa].
