Habitat. — East Coast of America; South Carolina, Texas, 

 Louisiana, south to Surinam ; chiefly in fresh water. 



As Cuvier and Valenciennes have identified the type of Bloch's 

 Scieena maculata with their Eleotris mugiloides, we adopt the 

 latter name for this species. We are unable to distinguish the 

 somnolentus of Girard from maculatus, and the omocyaneus of 

 Poey is certainly the same. Gill's lineatus is also, doubtless, a 

 young example of the same type. 



We find nothing (unless it be the greater height of the fins) in 

 the description of Eleotris gundlachi Poey, by which it can be 

 distinguished from Dormitator maculatus. Poey 's type was about 

 8 inches in length, and its large size ma}' account for the slight 

 differences indicated. 



The single specimen studied by us is from the West Indies.
