Describes from the Saint John group, the new genus Camerotheca, 

 with the new species C. gracilis as the type. He refers to this genus 

 Hyolithes danianus {Bull. No. 10 U. 8. Geol. Survey). In a note the 

 author states that, after seeing the specific description of Eichwald's 

 typical species S. acutus, he considers it necessary to place Camerotheca 

 as a subgenus of Hyolithes.

 Paradoxides, P. Davidis, in America. Amer. Jour. Sci., 3d ser., vol. 

 XXX, pp. 72, 73. July, 1885. New Haven. 



The author states that he has received from ]\Ir. J. P. Ilowley, direc- 

 tor of the Geologiial Survey of Newfoundland, fragments which appear 

 to belong to the species Paradoxides Davidis. They occur in a hard 

 black silico-calcareous shale at Highland's Cove, Trinity Bay, New- 

 foundland, in company with species of Agnostus, A. punctuosxis Aug., A. 

 Iwvigatus Dalm., A. Acadicus Hartt (var. decUvis Matthew). These fos- 

 sils indicate a new horizon in the Paradoxides beds of America some- 

 what above that of Braiutree, or the known horizons of Newfoundland 

 and New Brunswick. [It may also occur in the Cambrian slate of 

 Saint John, New Brunswick.]
