Unpublished paper, 'Observations on the anatomy of the antennae in a small species of crustacean' by John Denis MacDonald

Reference number: AP/34/16

Date: December 1852

Description

Macdonald 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

Received 3 March 1853. Read 7 April 1853. Communicated by Sir William Burnett.

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

Whilst the Royal Society declined to publish this paper in full, an abstract of the paper was published in volume 6 of Abstracts of the Papers Printed in the Philosophical Transactions of the Royal Society of London [later Proceedings of the Royal Society] as 'Observations on the anatomy of the antennae in a small species of crustacean'.
