CifARLES D. Walcott. Descriptiou of new Forms of Upper Cambriau Fossils. 

 Proc. U. S. Xat. Mas., XIII, No. 82i), October 14, 1890, pyi. 267-279, pis. xs, xxi. 

 There is included in this paper the description of a new species of Upper Cambrian fos.sils 

 and the new genus SpirodentaUum. The oi'currence of the latter and the genus Conularia 

 add to the downward range of two types that have hitherto been found only above the Cam.

 Charle* D. Walcdtt. Tlie Fauna of the Lower Cambrian or Olenellus Zone. 



Tenth Annual Report of the U. S. Gmlogl-nl Suroey, 1888 '89 (1800), part I, pp. .509-6.58. (Col- 

 ored map, text illustrations, 69 figures, plates xliii-xcvii). 



This is an extended work upon the geological and paleoutogical rliaracter of the Lower (Jam- 

 briau terrane of North America. 



The scope of the paper embraces (1) a list of titles of the more important books and papers 

 relating to the subject; (2) a historical review of the work on the rocks and fossils now in- 

 cluded in the Olenellus zone; and (li) the general results of the study of the fauna bv the 

 geologist and paleozoiilogist. or its physical and biological history and character as far as 

 known. The geologist considers it as found in certain rocks at a distinct geologic horizon, 

 and studies its geologic relations. The paleozoiilogist treats of it in its relations to the ani- 

 mal world, past and ])resent. 



Under the section of the Lower Cambrian or Olenellus Zone there is a table showin"- the 

 classification of the Paleozoic and tlie subjacent strata, and also one of the detailed classifica- 

 tion of the Cambrian group. Part VI deals with tlie North American continent during Cam- 

 briau time, and pai-t vu with the continent of Europe during the deposition of the sediment 

 now forming the Olenellus zone The geographic distribution of the Cambrian rocks is de- 

 scribed in part vui, and in part IX the relations of the Lower Cambrian fauna to the super- 

 jacent faunas are discussed. In the notes on the genera and species reference is made to each 

 genus and species known, and a description given if it has not been published in any of the 

 Geological Survey reports. All of the species are fully illustrated on the fifty-one plates ac- 

 companying the memoir. A map illustrating the distribution of the Cambrian strata in North 

 America, and one showing tlie typical sections of the Cambrian strata in North .America, ac- 

 company the text.
