NOTES ON VELIGERS OF JAPANESE OPISTHOBRANCHS (3)

Abstract

Succeeding my previous papers on the veligers of seven Japanese opisthobranchs, here is presented the third paper of the same series in which the following three species are treated: they are Philine japonica LISCHKE and Doridium gigliolii (TAPPARONE-CANEFRI) of Philinacea, both collected from the Zostera-zone at Tannowa on the southeastern coast of Osaka Bay, and Goniodoris sugashimae BABA of Okeniidae ( = Goniodorididae) caught at Kada situated about 9.5 km southwest to Tannowa. The observations were made on egg-masses spawned in my private laboratory by animals collected at the above-mentioned localities.
