Both evidences are misprint of 騭.

The first evidence 馬牡曰～ indicates ⿱陟鳥 is a name of horse. The text is from 《爾雅·釋畜》which gives 騭. https://ctext.org/library.pl?if=en&file=80276&page=105

The second evidence mentions 桑原 隲蔵（くわばら じつぞう）. 隲 is semantic variant of 騭.

The character is not included in the first evidence. The scholar mentioned the second evidence was a famous historian in Japan. The followings are his books.

All the books are not related to the submitted character, so it is not better to encode it.

Suggest to withdraw this character along with 04814, as the evidence for 04739 suggests that it is a misprint.

Otherwise, if the evidence for the simplified character is accepted, keep both.

We checked books by 桑原隲藏 dated before the publishing of 桑原隲蔵全集 (1968) in the University of Tokyo library. As far as we have found, his personal preference is apparently 隲, as well as the most of its typed representation. In the scope of his Japanese works, 𨽥 appears in limited instances as calligraphic stylized title on the cover or the title page, but we are unable to find it in the text body.





Among those books, 支那の孝道 and 東西交通史論叢 contain photocopy of his manuscript, clearly showing the 隲 variant in his handwriting.




On the contrary, Chinese translations appears to more eagerly employ 𨽥.

《張騫西征考》 consistently uses it:


and 《唐宋貿易港研究》 uses it partially in the colophon and a couple of chapter headings, while 隲 in elsewhere:




Aside from that, the government gazette records his name around 30 times, but except for his obituary, which also uses variant of 桑, no evidence that other variants than 隲 were used during his lifetime.

We did not find any evidence 桑原隲藏 has been written with the 鳥 component.

The fifth image of #9693 is wrong. Please see the following instead:

The former evidences show the wrong glyph of 騭 and 隲, withdraw would be better.
