T\' niTEAVES, J. F.— Paleozoic Fossils, (vol. iii, part 1, Geol. and Nat 

 Hist. Siirv. Canada. Montreal, March, 1884, pp. 1-43, pis. i-viii.) 

 This part is on some new, imperfectly characterized, or previously 

 unrecorded species of fossils from tlie Guelph Formation of Ontario. 

 The lists of the fossils of this formation in the "Geology of Canada" 

 contain the following names, for the species of which no descriptions or 

 figures have ever been published, and which, consequently, it has been 

 impossible to recognize : Columnaria galtensis, Biphj/phj/liiim irregulare, 

 Am.plexus lascatus, Cyclonema galtcnsis, G. Tliysbe, G. Fsyche^ G. depressa, 

 Pleuroiomaria Iiaroneiisin^ MurchiHonia tulUa, Gijrtoceras jonesi The 

 present author describes two new genera, Pyanostylus ami Coflonocheilus, 

 and the following new species: Fycnostylus guelpliensis, P. eleyans, Mono- 

 merella orata, 3L ovata var. lata, Goitiophora crassa, Anodontopsis con- 

 cinna, Tlionia galtensis, T. f eostulata, tSuhulites compactus, Godoncheilus 

 striatum, Troclionema inornatum, Straparolbis crenulatuH, Pleurotomaria 

 cyclostoma, P. durJiamemis, Murcliisonia lieHpelerensiH, M. constricta, M. 

 soluta, M. tropidophora, Tryhlidium canadense, Scenella conica, EccuUom- 

 phalm circinaius, Ascoceraa townsendi,, EurypteruH boylei. 



Whitfield, K. P. — Notice of some new Specnes of Primordial Fossils 

 in the Collections of the Museum, and Corrections of previously de- 

 scribed Species. (Bull. Amer. Mus. Nat. Hist., February, 1884, vol. 

 I, No. 5, pp. 139-154, pis. xiv and xv. New York.) 

 Mr. Whitfield thinks that the typical New York Potsdam is about 

 equivalent to the lower portion of the Wisconsin areas, and that the 

 Acadian beds of Canada and Vermont and perhaps the other Atlantic 

 areas are not appreciably different in age, but that the difference in 

 faunae is more the result of conditions upon which life depended than 

 a difference in time. Mr. Whitfield was probably unaware of the fact 

 that 3,000 feet of limestone without a break separate the Georgian 

 from the Potsdam fauna in Central Nevada. He describes the following 

 new species : Lingulepis minima, Orthisina orientalis, Nothosoe rermon- 

 tana, Gonocephalltes verrucosii,s, ArioneUus quadrangular is, Angelina 

 hitchcocld, JJikellocephalus? marcoui, Maclurea wadsworthi.

 the Meridian 70° 30' from Tompkins County, New York, to Bra<lford 

 County, Pennsylvania. (Bull. U. S. Geol. Surv., vol. i, No. 3, pp. 

 55-86. Washington, 1884.) 

 This paper is the first of a series ; it contains an interesting discussion 



of the relative positions of the Upper Devonian faunas of the meridian 



of Ithaca, N. Y. Mr. Williams does not always explain clearly where 



his stations, designated by numbers, are located.
