168 Miscellaneous. 



it was made into a skeleton, and then Dr. Giinther discovered that 

 the skull at the College of Surgeons and the skull of the Lizard I 

 had named Hatteria were most probably the same. It should now 

 be called SpJienodon punctahiin. 



I was much struck with the peculiar formation of the skull, and 

 that induced me to describe it ; but I did not then attach the great 

 importance to its structure that Dr. Gihither has since done : I only 

 regarded it as one of the variations of structure that are found in 

 most families. Indeed, when I consider the almost universal dis- 

 inchnation that zoologists have shown, almost up to this time, 

 to admit the distinction of the two great families of Lizards, 

 Agamidae and Iguanida3, which are so well characterized by the 

 teeth and geographical distribution, it would have required more 

 than usual hardihood in 1831, when the genus was described, to 

 venture to form for it even a family ; while an order may now be 

 suggested for the single genus, with every probability of its being 

 adopted— a decided proof of the progress of the science in a few 

 years.

To the Editors of the Annals and Magazine of Natural History. 



Gentlemen, — You will confer a favour on me, and, at the same 

 time, enable me to acknowledge an act of courtesy on the part of 

 my friend Dr. E, Perceval Wright, by inserting in the 'Annals' the 

 following correspondence, which has already appeared in the pages 

 of ' Scientific O^jinion.' 



I remain, Gentlemen, 



Yours very faithfully, 

 Kensington, Jan. 13, 1869. G. C. Wallich. 



" To the Editors of Scientific Opinion. 

 " Deep-Sea Dredging and Dr. Wallich. 



" Sir, — I neglected to read ' Scientific Opinion ' for the 16th inst. 

 until a day or two ago, when I perceived you had done me the ho- 

 nour of transferring to your paper my few brief notes on ' Dcep-Sea 

 Dredging,' published in the ' Annals and Magazine of Natural His- 

 tory for this month. I was, however, at the same time very much 

 grieved to find, from a footnote which you have appended to the 

 first portion of my notes, that I have appeared to yoii to make little 

 of Dr. Wallich's researches. 



" I assure you and my friend Dr. "Wallich that nothing was further 

 from my thoughts. Few arc, I think, better acquainted with the 

 writings of Dr.Wallich than I am, and I yield to none in my appre- 

 ciation of their value. Science has lost a great deal by the delay in 

 the publication of the second part of his ' North-Atlantic Sea-Bed ;' 

 and no matter what may be the discoveries of future investigators, 

 it is to the Rosses and Wallichs that we are indebted for our truest 

 and earliest information on the subject.
