The Spirifer nucleolus of Kutorga,' found in the Mountain Limestone of Sterlitamak, 
has a close resemblance to this species. 
Camarophoria globulina occurs in the shell Limestone of Humbleton Quarry, 
Tunstall Hill, Dalton-le-Dale, and Ryhope Field-House Farm ; but not so plentifully as 
the last species: it is also found in the Breccia of Tynemouth.

Diagnosis —* Subtriangular, somewhat poimted behind, rounded in front, and a 
little wider than long. Dorsal valve with a round incurved beak, slightly inclined 
lateral surfaces, and a broad deep flattened mesial furrow. Ventral valve with strongly 
inclined lateral surfaces, and a wide prominent flattened mesial ridge. Both valves 
with numerous small obtuse folds, from five to eight in the furrow, and seven or more 
on the lateral surfaces.’” 
Camarophoria multiplicata is a larger species than C. Schlotheimz, attaining sometimes 
thrice the size of the latter: it is in general more finely and numerously ribbed: in 
other respects both species have a striking resemblance to each other; so that many 
might easily fall into the error of considering one to be an adult form of the other. 
Comparing, however, full grown specimens of C. Schlotheimi with those of corresponding 
size (young) of C. multiplicata, the difference between them will be readily recognised ; 
imasmuch as the latter has a decidedly more compressed form, and its median 
sinus is only slightly produced (vide Pl. VII, fig. 32). Although stated in the 
diagnosis to be subtriangular, as represented in Pl. VII, fig. 28, many specimens are 
found with a subpentagonal outline (vide Pl. VII, fig. 26), and therefore so far 
simulating C. Schlotheimi. Some specimens have the anterior prolongation of the 
perforate valve falling so rapidly below the sides, or, in other words, projecting so 
little in advance of them as to make the shell appear much wider than long. (Compare 
specimens represented in Pl. VIII, figs. 1, 2.)
