EASTMAN: FISHES FROM UPPER EOCENE OF MONTE BOLCA. 337 



D. S. Jordan it seemed preferable to regard it and also the holotype of " Crenila- 

 brus " szajnochoB as pertaining to a distinct genus. This suggestion of Dr. Jordan 

 is now adopted, and the two previously described specimens together with two 

 additional examples belonging to the Carnegie Museum and figured in the present 

 paper, are placed in a new genus, Eolabroides, of which the diagnosis has just been 

 given, and the specific characters of the type-species redefined. 



Both specfmens belonging to the Carnegie Museum are preserved in counter- 

 part. The larger of them is cataloged under separate numbers, one for each half 

 (4340 and 5303). The two halves of the smaller specimen are cataloged as 4331 

 and 4331a respectively. One of the counterparts of each specimen is figured in 

 the accompanying plates, and that bearing the catalog number 5303 has been 

 submitted to Dr. Gill for examination, he having expressed a desire to study its 

 characters, and in particular to compare the skeleton with Agassiz's figure of a 

 unique fish from Monte Bolca, named by him Toxotes antiquus. 



Concerning the type of the last-named form. Dr. Gill is convinced that it has 

 nothing in common with the modern freshwater group of Toxotids or archer- 

 fishes,^" all referable to a single genus, but on the whole is unwilling to speak con- 

 fidently as to its precise systematic position, like Agassiz himself, who was per- 

 plexed to locate the example of the so-called " Toxotes antiquus " which came 

 under his observation. 



Under date of May 28, 1913, Dr. Gill has been kind enough to state for the 

 writer's benefit his conclusions on these matters in the following paragraph of a 

 personal letter: " The specimen figured by Agassiz does not belong to the genus 

 Toxotes, as is evident from the general form, the development of the fins, and the 

 abdominal cavity. The specimen you have sent me is not congeneric with Agassiz's 

 and is, so far as the evidence goes, a Labrid. I cannot identify it with any recent 

 form, however. If my count is correct, it has the fin-formula : 



D. XIV -f 14; A. Ill +6 ; C. 5+13 (branched) +4. 



I will count the rays again. Give my kind regards to Dr. Holland, and explain 

 why I did not acknowledge receipt of the specimen before." 



In a subsequent letter, dated August 21, 1913, the same eminent authority 

 makes the following additional statement: 



" The so-called Toxotes antiquus of Agassiz is entirely distinct generically 

 from the modern genus Toxotes, and I doubt whether it belongs to the same family. 

 The two differ in these respects : —
