on a basis of lava. The stage halted for a short time to enable me to 

 examine the shore of the lake. I found it to be lined with a windrow 

 of grasshoppers {Caloptenus spretus) which had fallen into the water 

 and been washed up, some living, otbers dead. Among them I found 

 numerous large fat larvae of Spea homhifrons occupying small spaces 

 which tbey had clearetl, quite out of the reach of the water. Their 

 limbs were nearly fully groAvn, while their tails had suffered no absorp- 

 tion, and their jaws were toothless and cartilaginous ; some quite larval 

 in form, others with wider gape. They were engaged in eating the 

 grasshoppers, and I detected several specimens with the entire insects 

 in their mouths. In some instances the grasshoppers' bodies were too 

 large and projected from their mouths. These precocious larvj© were 

 evidently air-breathers, and hopped about, presenting a curious ap- 

 pearance as they dragged their large tails after them. 1 found some 

 adnlt specimens of Amblystoma mavortium also along the water's edge. 

 These observations were made on the 11th of August, 1870.
