154 THE CAMBRIAN. [r.m.L.81. 



olites annularius (p. 34), A gnostus desiderates (p. 39), and Zacanthoides 

 eatoni (p. 45), from Washington County, and Camerella minor (p. 30), 

 from Dutchess County, New York ; Kutorgina cingulata, var. swanto- 

 nensis (p. 30) from northern Vermont. 



In 1890 the following new species were described : l Trachyum vetustiim, 

 Dawson, from Metis, Canada; Phyllograptus cambrensis, from Georgia, 

 Vermont; Stenotheca (?) rugosa var. acuta costa, erecta, and levis, Pla- 

 tyceras dawsoni, from St. Simon, Quebec; Olenoides ellsi, from below 

 Quebec, Canada; 0. desiderata, from Highgate Springs, Vermont; Cono- 

 coryphe reticulata, from Washington County, New York; Ptychoparia 

 metisensis and Agraulos redpathi, from below Quebec. 



SOUTHERN APPALACHIAN DISTRICT. 



NEW JERSEY, ETC. 



The Cambrian fauna of New Jersey, Delaware, Pennsylvania, Mary- 

 land, and Virginia is thus far restricted to the presence of the Annelid 

 boring Scolithus linearis. It is extremely probable that trilobites and 

 other fossils will be found in the Granular Quartzite series, or the basal 

 quartzite and the immediately superjacent shales and limestones. 



TENNESSEE. 



The Cambrian fauna of Tennessee consists of Scolithus linearis tubes 

 found iu the Chilhowee sandstone; while in the shales just above the 

 sandstone occur numerous Annelid trails, a species of Hyolithes like 

 H. americaiius, an Ostracod crustacean, Isoxys chilhoiceana, and a spe- 

 cies of Olenellus closely allied to Olenellus thompsoni and 0. asaphoides 

 in that portion of the head preserved. 2 



From the upper part of the Knox shale Prof. J. M. Safford 3 has 

 named, without description or illustration, several species, as follows : 



Crepicephalus siruilis, Safford. 



roanensis, Safford. 



tennesseensis, Safford. 

 Lonchocephalus fecundus, Safford. 

 AgDOstus arcanus, Safford. 

 Lingula prima ? Conrad. 



Quite a large fauna occurs at this horizon in the collections of the 

 Geological Survey which has not yet been studied with care. As far 

 as examined it appears to be of the type of the Upper Cambrian of the 

 Mississippi Valley.
