THE LOWER CRETACEOUS GRYPH^EAS <>F THE TEXAS RK<;K>N. By 

 ROBERT T. HILL and T. WAYLAXD VAUGHAN. (Bull. 151, U- S. 

 Geol. Survey.) In the introduction to this work there is an ac- 

 count of the great controversy that arose between Prof. Jules Mar- 

 cou and other American paleontologists "concerning the species 

 Gryphcea pitcher i, Morton, and the formation in which it was 

 found." 



"By the erroneous impression given to Dr. Roemer, through the 

 careless preservation of original type specimens, the first confusion 

 of Morton's G. pitcher) with other species of Gryphcea was started, 

 and the nucleus was created for an almost endless misrepresentation 

 and conlusion of forms, which has so permeated all the literature 

 of the country that the task of correcting it at times seemed almost 

 impossible." 



The variations of Gryphwu <-orrti</(t1<t. Say 182;; ( G. pitcher*, Mor- 

 ton, 1834), called by Maroon in 1851 G. f it </<<///;, nrc now known 

 to Ite Lower Cretaceous. 



"Mr. Stanton's (Hull 100. U. S. Geol. Sur. pp <;<>-<;_>). recent 

 studies of Newberry and Schiel's Grj f p/i j (f />/Yr//ov from the Upper 

 Cretaceous of New Mexico and Utah shows it to be a distinct spe- 

 cies (G. If eirbei- r i/i, Stan.), and removes the last vestige of G. pitch 

 en' from the Upper Cretaceous 



" A review and classification of the fossil Oslreidae of the Texas re- 

 gion is given, after which is a historical statement of the discovery 

 of the forms referred to. G pilchei'i, Mort, and the geographical 

 and stratigraphical distribution of the Lower Cretaceous Gry- 

 phseas." 



A description of species follows G, tt-(ii'<li\$ described as new, 

 and for G . i>i1cliet'i, Blake (not Morton) the name of (i . tmircoui is 

 pn>po>ed. The other forms that have been referred to, G pildtcri. 

 etc., by various authors, are here arranged under four species: G. 

 <-<>rnt</<t/(t. Say: G. narfa. Hall; G. ii'iixhituoixix. Hill, and (,'^ 

 /ii/icrotiata,Gsib]). The work contains <!<-; pp. of text and is pro- 

 fusely illustrated by 35 plates.
