" The appearance of the animal when in this position is wonder- 

 fully like a frog with a very large mouth, the marked division between

horizontal attitude, elongating the body, and propelling itself with 

 a frog-like motion, by opening and contracting its arms. 



" When I poured off the water, it discharged, at two or three jets 

 through the siphons, a small quantity of black fluid, which remained 

 undissolved for some time, in small cobweb-like clouds, floating 

 about on the water. It has the power of contracting the skin above 

 the eyes, so as to make a small horn-like projection ; but this only 

 rarely appears. The belly gives you more the idea of a snout than 

 of anything else ; it is about the size of a full-sized Turkey's egg. 

 It walked high, on the tips of its arms (see fig. 2)."
