404 G. li. Eastman — New Elasmobranclis from Solenhofen. 



Genus Rhinobatub Bloch (Schneider). 



Rhinobatus bugeslacus (Thiolliere). 



As recognized by Dr. A. Smith Woodward, the type of 

 Wagner's so-called Spathobatis mirabilis is only a large 

 variety of this species, which was founded by Thiolliere upon a 

 complete skeleton from the Lithographic stone of Cirin (Ain), 

 France.* The Bavarian specimen serving for the type of 

 Wagner's species is a magnificent example measuring l"7 m in 

 length, with well developed clasping organs, and preserved in 

 counterpart. The original of Wagner's and Zittel's studies is 

 in the Munich Museum, and the opposite half now forms part 

 of the exhibition series of the Carnegie Museum. It is note- 

 worthy as being probably the largest and most perfect example 

 of a fossil ray thus far discovered. 



* Thiolliere's final work, a large folio published shortly before his death, 

 bears the title : Description des Poissons Fossiles provenant des gisements 

 coralliens du Jura dans le Bugey. Lyons, 1854. 



The close affinity between Phorcynus and the type of Wagner's genus 

 Palaeoscy Ilium appears to have been overlooked by students of fossil fishes 

 generally. The former is conjecturally associated with Squatina by Smith 

 Woodward.
