| Title | Paper, 'The early development of Julus terrestris' by F G [Frederick Granville] Heathcote [Frederick Granville Sinclair] |
| Creator | Heathcote; Frederick Granville (1857-1914); Scottish zoologist |
| Date | [1885-1886] |
| Description | Heathcote writes: 'The following are the principal results of my investigations on the early development of Julus terrestris since June, 1882. When laid the eggs are oval in shape, white, and covered with a thick chitinous chorion. The nucleus is situated in a mass of protoplasm in the centre of the ovum. This mass of protoplasm is of irregular shape, but its long axis corresponds with that of the ovum. From it, anastomosing processes radiate in all directions, forming a network throughout the egg. The yolk-spherules are contained within the meshes of this network. The nucleus is not a distinct vesicle but its position is marked by chromatin granules. There is no nucleolus.'
