 longitudinal blackish or violet coloured streak, 

 separating the green of the upper parts, from the 

 M'hite colour of the lower : the inferior edge of this 

 dark lateral stripe is tinged with yellow. The body 

 is smooth above, and moderately short or plump :

 with small glandular granules in such a manner 

 as to fasten closely even to the most polished sur- 

 face : and the animal can adhere at pleasure to 

 that of glass, in whatever position or inclination

 winter it retires to the waters, and there submerg- 

 ing itself in the soft mud, or concealing itself 

 beneath the banks, remains in a state of torpidity, 

 and again emerges in the spring, at which period 

 it deposits its spawn in the waters, like the rest of 

 this genus. The male at this period inflates its 

 throat in a surprising manner, . and exerts a very 

 loud and sharp croak, which may be heard to a 

 vast distance. The spawn is deposited about the 

 end of April, in small clustered masses ; the 

 inclosed globules or embryos being of a pale
