mitsukurii, Chimaera Jordan [D. S.] & Snyder [J. O.] (ex Dean) 1904:224, Fig. 2 [Proceedings of the United States National Museum v. 27 (no. 1356); ref. 20652] Japan. Holotype (unique): CAS-SU 7739 (not found in 1997). Non-type material: ZUMT 1457 (1), 1473 (2 egg cases). Type catalog: Aizawa et al. 2022:210 [ref. 39648] with syntypes. Appeared as above, with a statement, (p. 223), "The latter is a new species, and Dr. Bashford Dean tells us that he has proposed for it, in a paper still unpublished, the name Chimaera mitsukurii. The name we accept in place of one devised by ourselves." Dean's account was published 3 weeks later (Dean 1904:6, Pl. 1 (figs. 1-2) [ref. 15183]) and is based on different specimens; it is a homonym (and presumably a synonym) of Chimaera mitsukurii Jordan & Snyder. •Valid as Hydrolagus mitsukurii but author as Dean -- (Nakaya in Masuda et al. 1984:17 [ref. 6441], Nakaya in Okamura & Kitajima 1984:75, 312 [ref. 8057], Didier 1995:15 [ref. 22713], Nakabo 2000:114 [ref. 25086], Shinohara et al. 2001:286 [ref. 25995], Nakabo 2002:114 [ref. 26001], Ebert et al. 2013:371 [ref. 33045]). •Valid as Hydrolagus mitsukurii (Jordan & Snyder 1904) -- (Choi et al. 2003:48, 468 [ref. 26218], Shinohara et al. 2005:392 [ref. 28370], Compagno et al. 2005:14 [ref. 29145] with author as Dean in Jordan & Snyder, Shao et al. 2008:236 [ref. 29952], Ebert et al. 2013:371 [ref. 33045], Shinohara et al. 2014:231 [ref. 33330], Dyldin 2015:78 [ref. 34524], Weigmann 2016:167 [ref. 34211] see remarks, Walovich et al. 2017:516 [ref. 35113], White et al. 2017:296 [ref. 35860] as cf. misukurii, White & Ko'ou 2018:69 [ref. 35922] as cf. mitsukurii, Miyazaki et al. 2019:122 [ref. 37957], Séret & Quod 2023:3 [ref. 40565]).
