156 MR. OLDFIELD THOMAS ON THE MAMMALS 



" ( i!rouia.nd.swal " respectively, so that the Greenland species of 

 Iliijht Whale may be at once accepted. 



Type locality ; Greenland seas. 



Mr. True, in his ' Nomenclature of the Whalebone Whales ' *, 

 comes to the same conclusion, for the same reason, after two 

 pages of discussion of what I venture to consider negligible 

 synonyms. 



2. PHYSALUS. p. 75. Balcenoptera. 



Linnean references : Faun. Suec. no. 265 ; Syst. ISTat. (6) 

 p. 39, no. 2. 



In both these places the reference is to Artedi (Gen. 77, 

 Syn. 107), to which alone validity should be attached. 



On reference to Artedi, we find Ray (Syn. Pise. 9) quoted 

 primarily, who in turn gives an abbreviated account of Martens's 

 " Finfisch." This has been shown by Mr. True to be a Common 

 Rorqual, to which, in agreement with him, I think the name 

 physalus should be applied. 



Type locality : Spitzbeig'en seas. 



The result is therefore the same as Mr. True's, but the steps are 

 formal, strict, and inevitable, and do not involve any balancing 

 of the importance to be attached to different synonyms. 



3. BOOPS. p. 76. BcdLBJioptera. 

 Linnean reference: Mus. Ad. Frid. i. p. 51 (misprinted 50). 



But this reference is wrong as to page, and the diagnosis is a 

 repetition of that of the succeeding species, B. mtisculus. 1 1 may 

 therefore be ignored. 



The next reference is to species iii. on p. 107 of Artedi's 

 ' Synonyms,' where in turn Ray's " Balsena tripinnis nares 

 habens ....'"' is quoted. The latter is based on Sibbald's 

 account of a whale which Mr. True shows to be the same as 

 the last species, B. physalus, of which, therefore, B. hoo])s is a 

 synonym. 



Type locality : Firth of Forth, Scotland. 



4. MUSCULUS. p. 76. Balcenoptera. 

 Linnean reference : Syst. Nat. (6) p. 39, no. 3. 



Here we get Artedi, Syn. p. 107, whence come references to 

 Ray (Pise. p. 17), and, at last, the real basis of all, Sibbald's 

 ' Phalainologia.' 



Sibbald's Rorqual. 



Type locality : Firth of Forth, Scotland.
