TWO NEW SPECIES OF GASTROPTERIDAE FROM GUAM, MARIANAS ISLANDS (OPISTHOBRANCHIA : CEPHALASPIDEA) [PDF]
Publications of the Seto Marine Biological Laboratory, 1973 In 1964 Tokioka and Baba established the genus Sagaminopteron to accommodate one species, S. ornatum Tokioka and Baba, 1964. According to Tokioka and Baba Sagaminopteron differs from the Gastropteron in that the former has a radular formula of 9-12.1.0.1.

THE GASTROPTERIDAE OF GUAM, WITH DESCRIPTIONS OF FOUR NEW SPECIES (OPISTHOBRANCHIA : CEPHALASPIDEA) [PDF]
Publications of the Seto Marine Biological Laboratory, 1974 From 1969 to the present the authors have maintained a regular log of the opistho branchs seen on Guam. Most of the study has been done in the area of Bile Bay, near the village of Merizo. During this time over a thousand specimens of Gastropteri dae, representing seven species, have been observed.

The complete mitochondrial genome of Haloa japonica (Pilsbry, 1895) (Cephalaspidea, Haminoeidae) [PDF]
Mitochondrial DNA Part B, 2020 Haloa japonica is a bubble snail species in the family Haminoeidae. In the present study, the complete mitochondrial genome of H. japonica was decoded and analyzed. With the size of 13,797 bp, the mitogenome of H. japonica is the shortest among all known mitogenomes of the order Cephalaspidea. Overall base-pair composition of the mitogenome was 69% A–T

Microscopical study of the crop and oesophagus of the carnivorous opisthobranch Philinopsis depicta (Cephalaspidea: Aglajidae) [PDF]
Journal of Molluscan Studies, 2011 A histochemical and ultrastructural study of the crop and oesophagus was carried out for the first time in Aglajidae. In Philinopsis depicta, the hind region of the crop contains two large folds creating a channel between them, lined by a ciliated epithelium. This ciliated groove continues through the posterior oesophagus.

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).

New Data on Chelidonura Amoena Bergh, 1905 (Opisthobranchia: Cephalaspidea: Aglajidae)
The Beagle : Records of the Museums and Art Galleries of the Northern Territory, 1995 Chelidonura amoena Bergh, 1905 is redescribed, principally on material from Australia. The single extant type specimen is designated as lectotype. Considerable intraspecific colour variation is evident, with that relating to the caudal lobes being greatest.
