the " Transactions of the British Association for the Advancement of 

 Science," 1861, p. 122, et seg., and in the " Geological Magazine," 

 February, 1870, Vol. VII, p. 49, and by Dr. Hector, in the " Trans- 

 actions of the New Zealand Institute," Vol. VI, p. 333 et seq., the 

 latter summing up the main results as follows (page 334) : — 



"The general result is that portions of 43 individual reptiles, 

 mostly of gigantic size and all of aquatic habits, and belonging to at 

 least 13 distinct species, have been discovered. These species repre- 

 sent two distinct groups, the first with flat or slightly biconcave 

 vertebrae, being true Enaliosaurians, belonging to the genera 

 JPlestosaurus, Mauisaurus* {gen. nov. allied to Elasmosaiirus of Cope), 

 and PolycotyJus (Cope) ; and the other having proccelian vertebrae, as 

 in most recent LacertiJia and Crocodiles, but provided with swimming 

 paddles, and therefore representing probably the order Pythonomorplia 

 of Professor Cope.f This order is represented in the collection by 

 two distinct genera, Liodon (Owen), and Ta?iiivhasaurus,i (gen nov. 

 allied to Clidastes of Cope.) In addition there are several fragmentary 

 remains, which, for the present, I only venture to place provisionally 

 under one or other of these groups, and two vertebrae, which appear 

 to belong to an exceptional form of the genus Crocodilus."
