172 CATALOG or rOSSIL FISHES IN THE MUSEUM 



In the Buffalo Museum there are a number of fine specunens of this 

 species, collected by Mr. Bryant at the type locahty, the Upper 

 Devonian shales on Scaumenac Bay, near the village of Megouasha, 

 Quebec, in August, 191 5.

E 2521 A small fish, 15 cm. in length, shown in side view. It 

 exhibits the head and all the fins. The head is imper- 

 fectly preserved but shows beautifully the posterior half, 

 represented by the impression of the upper surface. The 

 palatines are moved from their natural position, but 

 show in oral view. The most interesting thing about 

 the specimen is that the entire upper dentition, consisting 

 of both dipterine as well as both vomerine plates, is pre- 

 served. The dipterine plates are broken but agree in 

 their general characters with the description of these 

 plates given by other authors. The vomerines are stout, 

 and somewhat compressed. One, which is perfectly pre- 

 served, has two cusps or serrations; the other, two and 

 the "root" of a third. Each cusp is sculptured by a 

 broad, shallow furrow on the outer face. (PI. 57, fig. 3.) 



The discovery of a specimen of Scaumenacia showing the vom- 

 erine teeth is of very great interest. Another such specimen was 

 described by Hussakof in 191 2 ;8^ and in the same year Dr. William 

 Patten^ published restorations of Scaumenacia in which so-called 

 premaxillaries are indicated. Watson and Day^ have suggested that
