1920. Holcodiscus faku, v. Hoepen, loc. cit., p. 144, pi. xxv, figs. 3-4, 
pi. xxvi, figs. 1-2. 
1921. Madrasites faku (v. Hoepen), Spath, loc. cit., p. 47, and table 
to p. 50. 
This species is close to the last two, as pointed out by the writer on a 
previous occasion. 
25. Madrasites africanus, v. Hoepen sp. 
1920. Holcodiscus africanus, v. Hoepen, loc. cit., p. 146, pi. xxvi, figs. 3-5. 
1921. „ „ „ loc. cit., p. 23. 
1921. Madrasites africanus (v. Hoepen), Spaeth, loc. cit., p. 48, and table 
to p. 50. 
This was compared by the writer to M. buddhaicus (Kossmat), from 
which it differs merely in proportions. 
26. Madrasites aff. africanus, v. Hoepen sp. 
1921. Holcodiscus africanus ?, v. Hoepen, loc. cit., p. 23. 
A specimen of Madrasites was described by Dr. van Hoepen as being 
relatively thicker than M. africanus and showing other differences. 
27. Madrasites sp. ind. 
1906. Holcodiscus sp., Woods, loc. cit., p. 336, pi. xlii, fig. 2. 
1921. Madrasites sp. ind. (Woods), Spath, Pondoland, p. 48, and table 
to p. 50. 
This form has a smaller umbilicus and finer ornament than M. africanus. 
It was compared to Jacobites anderssoni by Kilian and Reboul,* and shows, 
indeed, close resemblance in the inner whorls to the form -figured by 
these authors on pi. vii, fig. 2, if one may judge by Professor Kilian's casts 
of his Antarctic specimens in the British Museum. Nothing like the adult 
Jacobites, however, seems to have been found in Pondoland, so that Mr. 
Woods's form is here considered to be nearer to the typical Madrasites 
madrasinus (StoL). 
28. Madrasites similis, Spath. 
1921. Spath, Pondoland, p. 48, pi. vi, fig. 1. 
This form was described as standing in the same relationship to (the 
tuberculate) M. faku as Kossmaticeras sparsicostatum (Kossmat) does to 
(the cost ate) K. theobaldianum (StoL).
