282 Notice of Modiolopsis pholadiformis. 



and interesting a subject in the midst of a poi^ulous and inquisitive 

 people, and only an hour's ride from a large and flourishing cit}^ has 

 not hitherto received a greater measure of investigation. 



Nofice of Modiolopsis plioladiformis (Foster and Whitney). 



Since writing the preceding monograph, I found, at Richmond, In- 

 diana, the cast of a modiolopsis, having a small part of the shell near 

 the hinge line, which shows strong folds or ribs starting from the hinge 

 line toward its base, and I believe it is most likely that it is Foster and 

 Whitney's Lake Superior species, Modiolopsis plioladiformis, which 

 they describe as follows : 



" Shell oval obovate, elongate ; base slightly arcuate in the middle ; 

 convex in the middle and compressed toward the posterior extremity ; 

 umbones prominent, hinge line slightly arched, and in some specimens 

 nearly straight ; muscular impression, large and strong, near the an- 

 terior extremity ; surface marked by. strong folds or ribs, which, orig- 

 inating on the hinge line, diverge and curve gradually downward to the 

 base." 



The strata at Richmond, Indiana, are the equivalent of the rocks 

 on the shore of Little Bay desNoquets, where Foster and Whitney pro- 

 cured their specimens. Beside the strong ribs starting from the hinge 

 line toward the base is a peculiar and remarkable feature, which indi- 

 cates with almost unmistakable certainty that our specimen belongs to 

 this species. The subject, however, will bear farther investigation, 

 and if it shall appear that our specimen does not belong to this species, 

 then it will belong to an undescribed species. . 



People who have no Idea of a Supreme Poioer. 



There is a general impression that all tribes of people have possessed 



.some idea of a Supreme Power, that guides and directs all things. But 



this is a mistake. There are many tribes of people even now that 



have no notions upon the subject, as will appear from the following 



extract from Sir John Lubbock's work on prehistoric times : 



" According to Spix and Martins, Bates and Wallace, some of the
