Spawn and development of Bulla striata (Opisthobranchia, Cephalaspidea) from the Western Mediterranean

, 1998
The egg masses of Bulla striata consist of very long gelatinous and cylindrical cords, irregularly coiled. The egg capsules are ovoid and measure about 161 x 137 μm. As a rule, each capsule contains a single embryo, but sometimes contains two, or rarely three. When freshly laid, the uncleaved eggs measure about 80 μm in diameter.

A Structural Analysis of the Spermatophore of Runcina Ferruginea Kress (Opisthobranchia: Cephalaspidea) [PDF]

Journal of the Marine Biological Association of the United Kingdom, 1985
A spermatophore is defined as a capsule of albuminous matter containing a number of sperm. Among opisthobranchs the families Retusidae, Philinoglossidae, Bullidae, Atydae and Runcinidae are all said to possess a copulatory apparatus which stores sperm and also forms spermatophores (Ghiselin, 1966).
