ou 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 sri^sahoitiK'vs (Culoptcnus mmtus) wliieh had fallen into the water 

 and been washed up, some living, others dead. Among them 1 found 

 numerous large fat larvie of S2)ea bombiJ'ronn oecupjing small spaces 

 whieh they had cleared, quite out of the reach of the water. Their 

 limbs were nearly fully grown, while their tails hadsuflered 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 

 grasshopper., and I detected several specimens with the entire insects 

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

 large and projected from their mouths. These precocious larva- were 

 evidently nir-breathers, and hopi)ed about, presenting a curious ap- 

 l)eaiance as they dragged their large tails after them. 1 found some 

 adult si>ecimens of AmbUjstonui mavortinm also along the water's edge. 

 These observations were made on the llth of August, 1870.
