tlier, based on a siu^ie specimen. This description agrees tairly well 

 with S. testudineus in all respects except the color of the curved streaks 

 on the back. These markings are said to be dark, while in all the ex- 

 amples of S. testiidmeus which we have seen they are paler than the 

 ground color. Further comparison will probably show the absolute 

 identity of testudineus, annulatus, poUtus, and formosus. but for the 

 present, the last two may stand in our list as doubtful species.

Type Tetraodon lineatus Linnaeus. 



In the subdivision of the old genus Tctraodan, there is some doubt as 

 to which of the several minor groups should retain the original name. 

 We may therefore glance for a moment at the history of the group. 



The name Tetraodon first appears as a generic term, so far as knowii 

 to us, in Hasselquist's Travels in Palestine, edited by Linuieus, in 1757. 

 We have not examined this work, but our impression is that it is bino- 

 mial in form, and that the name Tetraodon is here associated only with 



* This name, usually and preferably spelled Tetrodon, was originally given as Tetra- 

 odon by Linnseus. The latter form should therefore be used.
