 Campylodiscus daemelianus is equally hard to track down. Its first place of publication is usually given as Grunow in Schmidt (1874: fig. 4). While referring to Schmidt’s Atlas der Diatomaceen-kunde, it specifically refers to the ‘Probe-Hefte’ (the trial issue) published just after the first part of the Atlas proper, in July 1874 (the first [‘erstes’] Hefte of the Atlas, with plates 1-4, was published on January 1874, Hanna 1969: 1) comprising just one plate as an example of what one might purchase; it was designed to attract subscribers (see Hanna 1969: 1). This ‘Probe-Hefte’ plate has not been seen nor has any copy yet been traced – it must exist somewhere. Later, Campylodiscus daemelianus was figured again in Schmidt’s Atlas (Schmidt 1877: pl. 54, figs 1, 2, ‘Yarra, Yarra’ [Australia]).   
 There are several specimens in BM of Campylodiscus daemelianus var. comminuta A.W.F.Schmidt (in Schmidt et al. 1875: pl. 17, fig. 11, ‘Bengal’, BM Adams G832, ‘Bay Bengal, Indien’, F.W.Mills. one fragment). Interestingly, Campylodiscus daemelianus is reported as having two further varieties: ‘ Campylodiscus daemelianus var. fossilis Pantocsek’ (noted only in Mills 1933: 337 as ‘Moller’s slides’) and ‘ Campylodiscus daemelianus var. sonderianus ’, named, but not described, also apparently in Möller (1868) – neither name has been located in that particular catalogue. ‘ Campylodiscus daemelianus var. sonderianus ’ may simply be a proposed change of rank for C. sonderianus (see above). Deby included C. daemelianus in his study, and added two varieties as synonyms: C. daemelianus var. comminuta and C. daemelianus var. sonderianus, the latter he appends as ‘Grun. in litt. Möller slides’ (Deby 1891: 22, his figure 53 is a reproduction of Schmidt 1877: pl. 54, fig. 2).
