2. Imam,1996aImam,1996a AGUIRRE (2004) demonstrated that
photomicrograph 3.1 labelled
“Archaeolithothamnium saipanense” was reproduced
either from JOHNSON (1957*: Pl. 37, fig. 10, where
it was called “Lithothamnium sp.”; or from his 1961:
Pl. 2, fig. 1, “Archaeolithothamnium”.
We found that JOHNSON himself re-used this photo
in 1963: Pl. 25, fig. 3, again titled
“Archaeolithothamnium”) and that it was pirated
twice more in IMAM & REFAAT (2000: Fig. 7.5) and
in IMAM (2003: Pl. 3, fig. 1).
3. Imam,1996aImam,1996a In addition, we found that
1) photomicrograph 3.7 labelled “Lithophyllum
prelichenoides” was copied, but rotated 180°, from
JOHNSON & FERRIS (1949: Pl. 38, fig. 4,
“Lithophyllum aff. prelichenoides”), or from
JOHNSON (1961: Pl. 10, fig. 3, “Lithophyllum”, or
1971: Plate 92, fig. 3, “Lithophyllum”)

“Lithophyllum sp.”) and rotated 90° clockwise when
published;

Aguirre (2004) made an excellent re-evaluation of the
most recent Imam publication (2003). He found that:
1) the photomicrographs of red algae in Imam‘s Pl. 5,
figs. 2 and 4 are respectively those of Pl. 10, figs. 1
and 2 of Johnson (1961). He did not mention that
both of these illustrations had been first published,
respectively as Pl. 6, fig. D and Pl. 7, fig. D of Johnson
& Ferris (1950), also re-used one more time by
Johnson himself (1971: Plate 92, figs. 1 and 2).
2) Imam‘s Pl. 5, fig. 9 corresponds to Pl. 26, fig. 3 of
Johnson (1963). He did not mention that Johnson
(1961) had reproduced it from Pl. IX, fig. 2 of
Pfender (1926).
