Unfortunately, Ludwig introduced two nomina nova for Holothuria lamperti Sluiter, 1889 [non Holothuria lamperti Ludwig, 1886 a] (see Table 3).
Holothuria bataviae was erected by Ludwig on page 174 (footnote) (= fascicles 5 / 6 of Ludwig 1889-1892 = Ludwig 1889), but is probably a forgotten name since it is missing for instance in the annotated catalogue of Holothuroidea by Smiley & Pawson (1991) or in the World Register of Marine Species. However, Holothuria kurti (introduced by Ludwig in a footnote on page 329 = fascicle 13 / 14 of Ludwig 1889-1892 = Ludwig 1891 b) on the other hand gained acceptance to replace Holothuria lamperti Sluiter (e.g., Meissner 1895; Koehler & Vaney 1908; Sluiter 1914; Samyn et al. 2010). Lately Liao Yulin thought that H. kurti Ludwig, 1891 is probably a young H. (Theelothuria) ocellata (Liao 1980), other authors placed this species in the subgenus H. (Holothuria) and H. (Metriatyla) (cf. Rowe & Gates 1995).] Presently, H. kurti Ludwig, 1891 is considered to be a species of H. (Theelothuria) (Paulay 2014 b).
