370 * Analytical Synopsis of the Order of Squali. 



purposely arranged species with the design of placing a typical 

 one at the head. In the present case, for example, the Pristis 

 antiquorum is stationed as the first of the genus, yet it not only 

 entirely disagrees with the generic character, but is happily the 

 only one that does so ! On the other hand, the generic charac- 

 ters assigned by Artedi to the genus Raia are entirely appli- 

 cable to it. I can scarcely conceive that any one should seri- 

 ously apply the above-mentioned maxim to the name in question, 

 and urge the acceptance of the Squalus pristis as the type of 

 the genus.

 order of Squali among four genera which were essentially dis- 

 tinguished as follows : —

3. O. rostro brevi. 



II. Gale us S. Mustelus capite rostrato ; ore traiisversali, prono. 



1. G. acaniA2ffs = Squalus acantbias L. 



2. O. teyis^ Mustelus Isevis Flem.
