44 Professor King on certain Species of Permian Shells 
It therefore appears to be extremely improbable that I was 
able to perceive an identity in the former case and none in the 
latter. It must not be supposed that at that time I was un- 
acquainted with all the varietal forms assumed by the Per- 
mian species. 
I have gone somewhat into detail on the subject of Martin’s 
Anomites crumena, to show that there are strong reasons 
against admitting it to be the same as Camarophoria Schlo- 
theimi. Indeed, all circumstances considered, it appears to me 
that Martin’s shell will have to be put down as an apocryphal 
species. All that can be said with any safety is, that C. 
Schlotheimi existed both in the Permian and the Carboni- 
ferous period. 
Camarophoria globulina, Phillips. 
Very little is stated in my “ Monograph” on the relation of 
this species to any Carboniferous shell, except that it “ has a 
close resemblance” to “the Spirifer nucleolus of Kutorga, 
found in the mountain limestone of Sterlimatak.” Mr David- 
son, having far more materials to work on than Lhad, expresses 
himself as follows in his “ British Carboniferous Brachiopoda:” 
—‘ After a lengthened comparison of numerous specimens of 
Phillips’ Terebratula rhomboidea and T. semiluna, it appeared 
to me evident that the last was nothing more than a young age 
of the first, and that neither could be distinguished from the 
Camarophoria globulina of Phillips. The resemblance was in- 
deed so great, that having mixed several specimens of each it 
was with some difficulty that they could be afterwards sepa- 
rated” (p. 116). 
I cannot but express my agreement with Mr Davidson in 
this case,—of course with some reservation, founded on con- 
siderations elsewhere stated in this paper. At the time my — 
remarks on this species were written, I had not an opportunity 
of consulting Phillips’ figures of C. rhomboidea in his “ Geo- 
logy of Yorkshire: besides, looking at the figures (the only 
ones J was then able to consult) in his “ Paleozoic Fossils” of 
a shell therein identified with this species (Pl. xxxv. fig. 158, 
a b), it will readily be explained how it happened that I had 
not arrived at the same conclusion as Mr Davidson. The —
