[The 10th.] THE VARIOUS EXPLANATIONS. 433 
We only observe that Mr. Gossn is evidently inclined to believe 
that there are “two or more species inhabiting the Northern and 
Southern oceans.” It is not at all plain what circumstance has led 
him to this supposition. 
Curious is the comparison of the flappers, figured by Mr. Brine (fig. 19) 
with the frill of the Chlamydosaurus. | give here a figure of such an animal. 
Mr. Gosse gets clearly entangled in his own considerations of 
the affinity of the sea-serpent with the Plesiosaurus when he comes 
to the fact of the existence of a mane. It is a pity that he has 
not mixed up with his considerations the well-known Jguana tu- 
berculata, a lard belonging to the same family as the Chlamy- 
dosaurus, but which has a comb extending over the whole length 
of the neck, the back and the tail!

Mr. Lee in his Sea Monsters Unmasked, considering the Plesio- 
saurus hypothesis, says: 
“I think this theory is not forced upon us.” 
Of the probability of living Plesiosauri, however, he Says : 
“Only a geologist can fully appreciate how enormously the ba- 
lance of probability is contrary to the supposition that any of the 
igantic marine saurians of the secondary deposits should have con- 
tinued to live up to the present time. And yet I am bound to 
say, that this does not amount to an impossibility , for the evidence 
against it is entirely negative. Nor is the conjecture that there may 
be in existence some congeners of these great reptiles inconsistent 
with zoological science. Dr. J. E. Gray, late of the British Mu-
