Art. XXXIV. — New Elasmobranchs from Solenhofen in 

 the Carnegie Museum : by C. E. Eastman. (With Plates 

 I-III.) 



Several years ago, through the generosity of Mr. Andrew 

 Carnegie, the Museum founded by him in Pittsburgh received 

 a notable enrichment of its collections illustrative of vertebrate 

 and invertebrate palaeontology, especially from European hori- 

 zons and localities. By its acquisition of the famous Bayet Col- 

 lection, through the gift of Mf. Carnegie in 1903, the Pitts- 

 burgh Museum was at one stroke placed in the front rank of 

 American institutions as regards representation of the ancient 

 life-history of the globe in Old World formations. Remark- 

 able not only for its size and great wealth of fossil species, but 

 also for the excellent character of the material, this collection 

 is one of the largest and scientifically most important that has 

 ever been brought together by a single individual, and in .cer- 

 tain respects it stands unrivalled save by the larger public insti- 

 tutions abroad. 



The great strength of the Bayet Collection may be said to 

 lie in its magnificent series of vertebrate remains, especially 

 fishes, from European Mesozoic and Tertiary strata. Within 

 this category is to be included first of all the splendid suite 

 of fishes and flying reptiles from the Lithographic limestone 

 (Upper Jura) of Solenhofen, Bavaria, and from the correspond- 

 ing deposits of Cirin, France. Next in order of importance may 

 be reckoned the fish and reptilian remains (including at least 

 one complete Pterodactyl) from the Lias of central Europe, 

 and " blue Lias " of Dorsetshire. Nor would any mention of 

 this collection be complete which failed to speak of the large 

 variety of exquisitely preserved marine fishes, crocodiles, and 

 plant remains from the Upper Eocene of Monte Bolca, Italy. 



So much by way of brief comment on the surprising rich- 

 ness of the collection which has found a final resting-place in 

 the Carnegie Museum, and which embraces the material about 

 to be described in the following pages. For an opportunity to 

 study the entire assortment of fossil fishes belonging to the 

 Carnegie Museum, and for many privileges and courtesies 

 enjoyed during his temporary connection with the institution, 

 the writer is greatly indebted to the kindness of the Director, 

 Dr. W. J. Holland, and desires hereby to express his hearty 

 appreciation of the manner in which work upon the collections 

 has been encouraged and facilitated by Dr. Holland and his 

 assistants. 



It is not the purpose of the present article to notice all of the 

 interesting specimens of sharks and rays from Solenhofen
