In 《哥德尔、艾舍尔、巴赫——集异璧之大成》[translation of Douglas Hofstadter's "Gödel, Escher, Bach: an Eternal Golden Braid"] (商务印书馆, 1996) the character is written as ⿱卧龙. 尨 can be used as a variant form of 龍, and no doubt Yuen Ren Chao intended the character ⿱卧尨 to mean 卧龍, but Evidences 1-4 all use 尨 at the bottom, so ⿱卧尨 is the canonical form of the character which we propose for encoding. The form ⿱卧龙 could be considered a unifiable variant of ⿱卧尨, encodable using IVS.

Mimeographed typewritten draft (circa 1950-1966) for a translation of Through the Looking Glass using the Gwoyeu Romatzyh system of romanization for Mandarin, with Yuen Ren Chao's hand-annotated Chinese characters:

Note that the above evidence and the following page include hand-written unencoded characters ⿰犭偷, ⿰豸若, ⿰赤瓦, ⿱不亞, and ⿰赤禾 which are not used in the 1969 printed edition of Yuen Ren Chao's translation of Through the Looking Glass. Because these characters are only attested in a single hand-annotated draft we have not proposed them for encoding.

Evidence 3 also shows the unencoded characters ⿱罒二 and ⿱格兒, which are not attested elsewhere, so have not been proposed for encoding.
