TitleUnpublished paper, 'On the embryogeny of Comatula rosacea (Linck)' by [Charles Thomas] Wyville Thomson
Date1 November 1858
DescriptionThomson details his observations on the development and subsequent changes of the larva of Comatula rosacea. After complete segmentation of the 'yelk', a more consistent nucleus appears within the mulberry mass still contained within the vitelline membrane. The external more transparent flocculant portion of the 'yelk' liquefies and is absorbed into this nucleus, which gradually assumes the form of the embryo larva, a granular cylinder contracted at either end and girded with four transverse bands of cilia.

Includes one illustration of the Comatula rosacea larva. Marked on front as 'Archives'.
