Abstract
IN the Decapod Crustacea the female possesses characteristically long non-plumose setæ on many of the abdominal, and in some cases certain of the posterior thoracic, appondages. It is to these hairs that the eggs are attached when the animal is in berry. It has been further shown by one of us1 that in Homarus vulgaris ducts from the cement glands, which occur exclusively in the pleopods of the female, pass into the interior of these specialized setæ, “circumstantial evidence indicating that the secretion is discharged through the sides of these”. In other words a direct correlation was postulated between the setæ and the glands, the former providing the surface of attachment of the eggs and the latter the necessary binding cement.
