 lay northward. Servius on Virgil fays, that it belonged to

 badly reprefented by the engraver, who miftook the original 

 drawing of the feftion of an anther, for the germen, and 

 altered it accordingly. Capfule ovate, emarginate. Seeds

TETRODON, in Ichthyology, a genus of the Branchiof- 

 tegi order of fifhes, according to the arrangement of 

 Gmelin ; the characters of which are, th.at the jaws are long, 

 divided at the tip ; the branchis or gills have a linear aper- 

 ture ; the body is roughened beneath, and the ventral fins 

 are wanting. The fiihes of this genus, like the Chiodon, 



and had grown up again ; which proves them to be perennial have the power of inflating their bodies at pleafure, by 



plants, though fcarcely (hrubby. The fize of the prefent 

 fpecies, and its general afpcdl, agree with T. ericifolia, but 

 the corolla and antljers zre of a darker tint. The _/?fm is 

 clothed with very fhort clofe down, by no means briftly ; 

 whWe ilie Jlower-flalis and calyx, inftead of being fmooth, 

 are covered with glandular hairs. The leaves are rather 

 broader, and lefs whorled, being often merely oppofite, or 

 even difperfed.
