already mentioned. By the vomer furnished witk 

 small teeth it cannot appertain to Saurus nor to Sco- 

 pcles, in which the palate and tongue are smooth. 

 The scales are large, particularly on the sides, 

 and to the lateral line they are higher. Pectoral fin 

 rather large, continued parallel to the half of the dor- 

 sal ; ventral small, situated between the abdominal 

 and the pectoral ; the dorsal fin placed between the 

 pectoral and the anal ; the anal between the two dor- 

 sal, of which the second is very small and adipose. 

 The tail long and slender, terminated by a slightly 

 forked fin. Eyes rather large, silvery and gilded, 

 situated contiguous to the maxillary bones and the 

 snout.

 nicated to me by Mr. T. Nuttall, the botanist, who 

 obtained it in tlie river Arkansa.
