| Abstract: | A list of the 21 species represented in the collection by the bottom-net is given. Of these, 5 are impossible to be identified
with the already known species, especially 2 are reserved as their genera are undecided. It is found that there are 2 races
inHolmesiella affinis
Ii, the large-sized and the small-sized, as like as the most related species,H. anomala
Ortmann. As to a species,Pteromysis amemiyai
Ii, the development of the marsupium is discussed on the basis of an adult female collected by the ORI-net. The occurrence of
2 species,Petalophthalmus oculatus
Illig andPseudomma calloplura
Holt andTattersall, is a new record in the Pacific. For the former species, moreover, an ecological property of the habitat is discussed. |
