 shields ; supraorbital ridge continued over the tcmpond region ; 

 anterior part of the operculum with a faint ridge. Shields without 

 spines. Lateral line and upper caudal edge not continuous in the

Dr. Kaup's S. agassizii is not the species described by Michahellos 

 under that name, as he describes the latter as S. murcena ; but it is 

 identical with S. huccidentus of Rathke. 



On reading only the diagnoses of Dr. Kaup's S. agassizii and /S. 

 cuvieri, one is compelled to admit that the differences indicated would 

 be quite sufficient for specific distinction : 



S. agassizii is described as having the " snout as long as the head 

 From thirteen to sixteen rings anterior to llie dorsal fin. D. 22.'"
