duction, very much developed, and are continuous ; the mar- 

 gin is crenate throughout its length. The colour varies very 

 much in the course of the year, and even in different indivi- 

 duals at the same period. That of the male is also very 

 different from that of the female. The former is brownish 

 grey above, passing into yellow beneath, which in the spring 

 becomes a rich bright orange ; marked everywhere with round 

 dark spots of unequal size, but much larger and less numerous 

 than in the next species L, palmipes. On the head are two 

 longitudinal streaks. The crenations of the crest, in the spring 

 season, are often tipped with bright red or violet. The fe- 

 male is usually light yellowish brown, or even buff with scat- 

 tered brown dots, and the belly often quite plain.
