334 MEMOIRS OF THE CARNEGIE MUSEUM. 



specimens, so far brought to light, have been more or less distorted. One such, 

 preserved in counterpart and cataloged as No. 5317+5317a, is contained in the 

 lot of material from Monte Bolca, which originally formed part of the Bayet Col- 

 lection. Two others, smaller, but better preserved, are cataloged as Nos. 5322 

 and 5323. There are also preserved in the same collection two or three examples of 

 an allied form from the Lower Miocene of Chiavon, Vicentin, in northern Italy.

One is certainly safe in saying that no more perfectly preserved fish from the 

 Monte Bolca locality has yet been made known than the splendid example figured 

 by Massalongo in Plate IX of his work published in 1859. The identical specimen 

 now forms part of the Bayet Collection in the Carnegie Museum, and is cataloged 

 as No. 5305. It bears an original MS. label in an unknown hand reading: " E 

 I'esemplare figurato nella tav. IX. dello Specimen Photogr. di Massalongo."
