Eyerman, John. Footpriuts on the Triassic Sandstone (Jura-Trias) 

 of i^ew Jersey. (Am. Jour. Sci., 3d ser., vol. xxxi, p. 72. January, 

 1886. New Haven.)

Faber, Charles L. Remarks on some fossils of the Cincinnati group. 

 (Jour. Cincinnati Soc. Nat. Hist., vol. ix, pp. 14-20, PI. i. April, 1886. 

 Cincinnati.) 



Describes the new genus Lepidocoleus as distinct from PJnmiiUies, Barraude, 

 with L. Jamesi (Hall & Whitfield), Faber as the type. Describes also the 

 new species: Ci/cIoc>jsioides nilidiis, Ci/rtoceras tenuiseptitm, and gives a de- 

 scription of the genus Merocrinus, Walcott, and Merocrlnus curtus (Ulrich), 

 Faber. 



FiLHOL, H. Observations sur le memoire de M. Cope intitule relations 

 des horizons renfermant des debris d'animaux vertebras fossiles en 

 Europe et en Amerique. (Ann. Sci. Geol., vol. xvii, pp. 1-16. Ad- 

 denda. PI. vi., 1885. Paris.) 



Considers that Anaptomorphus and Necrolcmur, which Mr. Cope had thought 

 might be identical, although evidently belonging to the same group of 

 Lemuroids, are too different to bo joined zoologically under the same name. 

 Mr. Cope says "that the II>jrach'nis is the American Lophiodon, for there are 

 only slight differences between them; both exist in France, the second in 

 the lower Parisian, the first in the Phosphorites."' The present author 

 thinks it probable that the Ri/rachius, animals descending from the Lophi- 

 odon, lived both on the old and new continent and were represented in 

 France by four species, //. 2»'isctis, II. Donvillei, II. ZeiUeri, and H. interme- 

 dins. 

 Future discoveries will enable us to understand the changes effected in the 

 Hyrachius, which must have modified themselves progressively to give birth 

 to the Ta[)irs. •
