THE " GENUS PUSA" OF SCOPOLI. 685 



actly wliat he meant, in spite of his inept diagnosis; his name 

 Pusa therefore holds, and cannot be subsequently used by 

 Oken in a different connection." * 



An examination of the case, however, shows that Miiller's 

 plate is not "recognizable with certainty" as that of any par- 

 ticular species of Seal. Scopoli's diagnosis is simply an ab- 

 surdity, as the subjoined transcript t sufficiently shows, his 

 reference to M tiller's description and plate affording the only 

 real basis for his genus Pusa. As already stated, the figure 

 cannot be positively referred to any particular species of Seal. 

 The description given by Miiller { records few characters that 

 are not applicable to any species of Earless Seal. Those which 

 are not thus applicable appear to relate to Phoca grypus, Fa- 

 bricius, and I so at first interpreted the description, but later I 

 found it necessary to go further back in the history of the sub- 

 ject. The plates of Miiller's work, so far as the mammals are 

 concerned, prove on collation to be very close copies of those 

 given by Houttuyn (with the exception of three that appear to 

 be here for the first time published) twelve years earlier, if, in- 

 deed, some of them were not actually printed from the same 

 etchings. Miiller says (1. c., p. 201), " Der Professor Albinus in 

 Leiden zergliederte den 24. Februar, 1748. in Gegenwart des 

 Herrn Houttuyns einen Seehund, welcher Tab. XI. fig. 6. ab-
