 phy, most of the facts in this brief sketch have been taken. 



That America has produced such a man, and that the govern- 

 ment honors itself by pubHshing his biography is a matter for 

 honest pride and congratulation, on the part both of the scientist 

 and of the citizen. His hoary locks are a crown of glory not 

 only to himself, but also to his country. (Dr. Lea's death, on 

 Dec. 8, 1886; at his home in Philadelphia, has been announced 

 since writing this article.)

NEW CRETACEOUS FOSSILS. 



In the present volume of The West Ajuerican Scientist, pp. 8 

 and 21, we gave an account of the discovery of a new genus of 

 Chamidse, with the description given in bulletin No. 22, U. S. 

 Geol. Survey, by Dr. C A. White. In this number we give two 

 other plates illustrating the same fossil, together with a plate 

 giving the figures of the univalves referred to on page 11, for all 

 of which we are indebted to Prof. Baird and Dr. White. We take 

 the following descriptions by Dr. Charles A. White from the 

 same publication. 



Trochus (Oxystele) euryostomus, White. 



Shell small, depressed-subturbinate; volutions about four in 

 number, rounded, and, at the distol border, more or less distinct- 

 ly appressed against the preceding volution; aperture compara- 

 tively large, and, in adult shells, the inner lip is appressed against 

 the last volution as in callus covering of a portion of the base of 

 the shell, but its margin being a little elevated, it forms, together 

 with the thin outer lip, a continuous margin to the aperture. In 

 immature shells the callus of the inner lip is not formed, and the 

 margin of the aperture is therefore not then continuous. Surface 

 marked by numerous sharply raised revolving, somewhat crenu- 

 lated ridges, separated by grooves of similiar width. Height, 

 ^mm. greatest diameter of the I'ast volution; 8""". Locality: South- 

 ern shore of Todos Santos Bay, Lower California. 



Cerithium Pillingi, White. 



Shell small; spire comparatively short; volutions four and five 

 in number; each volution bearing four or five prominent longitu- 

 dinal folds, which are usually so arranged upon the spire as to 

 form continuous ridges along its whole length. These long ridges, 

 together with the flattening of the sides ot the volutions between 

 them, give a distinctly angular aspect to the shell. Volutions
