9月22日，一头属于中吻鲸属的喙鲸搁浅。1957年，东京附近相上湾的Oiso海滩。颅骨、脊柱(C7+D10+L10+Ca21=48)和人字形(11个)被完整收集。在分类中特别考虑了颅骨和下颌的4个明显特征，并在此基础上总结了该属的种检索表。作者决定为这一标本定下一个新种，并命名为中层银杏。1935年，小川报道了来自日本的第一个Mesoploden标本，并鉴定为M.densirostris。在目前的工作中，它被再次检查，并被鉴定为与新标本相同的种，即。银杏树。由于本公报篇幅有限，详细报告将刊登在第13号鲸鱼研究所《科学报告》上。
A beaked whale that belongs to the genus Mesoplodon stranded on 22 Sept. 1957 at Oiso Beach, Sagami Bay, near Tokyo. Skull, vertebral column (C7+D10+L10+Ca21=48), and chevrons (11 in number) were collected in a complete set. Four distinctive characters from skull and mandibular are taken into special consideration in classifying the species of Mesoploden, and a key to the species of this genus was summarized basing on these characters. The authors concluded to settle for this specimen a new species and nominated as Mesoploden ginkgodens. The first specimen of Mesoploden from Japan was reported by OGAWA and identified as M. densirostris in 1935. It was examined again in the present work, and identified as the same species to the new specimen, viz. M. ginkgodens. As the space is restricted in this bulletin, the detailed report will be published in the Scientific Reports of the Whales Research Institute No. 13.
