To this paper Biirnieister replied (Arch. f.Natur. xlii. vol. i. p. 1 16), 

 }ind after blaming- Phihppi for uoii-atteutioii to his figures, he

 it ranges from 100 and 107 up to 100 and 130. In 6'. vetulus of 

 Burmeister and the British Museum specimen like it (my C. parvi- 

 dens) it varies from 100 and 155 to 100 and 16(1. But there is in the 

 British Museum a very interesting skull ^ extracted from a skin, also 

 there preserved, which was bought of Claussen from Brazil. On its 

 label is a suggestion, made by an unknown author, that it may be the 

 C. brasi/iensis o( Lui\d (/. c. p. 10, pi. xlii. figs. 1-3), but this it cannot 

 be. Lund gives a side view of the skull (probably life-size), which 

 shows not only a strikingly different configuration, but an extremly 

 contrast as to the dimensions of the teeth. In his species the last
