Linuasus (Syst. Nat. i. 397) formed the sharks into three sections : 

 — 1. Dorsal-fin spinous, anal-fin none. — S. Acanthias. 2. Dorsal- 

 fin unarmed ; anal-fin distinct ; teeth acute. — S. Zygoma. 3. Teeth 

 granulated. — .S'. mustellus. 



Schneider (Syst. Ichth. 1801) divides them thus : — 1 . Spiracle 

 and anal-fin distinct. — S. canieula. 2. Spiracles none; anal dis- 

 tinct. — .S'. Zygoma. 3. Spiracles distinct ; anal none. — S. centrina. 



Rafinesque (Caratteri Nuovi Generi, 1810, 8vo.) described and 

 figured the following new genera and species of sharks : — I. Car- 

 charias Taurus, 10, t. 14, f. ]. — 2. Delatias sparophagus, 10, t. 13, 

 f. 4. — 3. D. noctunius, 11, t. 14, f. 3. — 4. Tetroras angivora, 1 1.— 

 5. Isurus oxyrhinchus, 12, t. 13, f. 1. — 6. Cerictius macrourus, 12. 

 — 7. Alopias macrourus, 12. — 8. Heptranchias cinereus, 13. — 

 9. Galeus melastomus, 12. — 10. Squalus uyato, 12, t. 14, f. 2. — 

 11. Hexanchus grissus, 12. — 12. Etmopterus aculeatus, 14, t. 13, 

 f. 3. In his ' Analyse de la Nature,'' 1815, he quoted these genera, 

 and added the following, but without characters or quoting types: — 

 13. Sphyrnias. — 14. Oxynotus. — 15. Squalina, hum. — 16. Pristes, 

 Lath. — 17: Anodon, Lac. 



M. De Blainville (Bull. Soc. Phil. 121, 1816, and Jour, de 

 Pltys. 260, 1816) divides the Squali in nine sub-genera, thus: — 

 1. Scyliorhinus (canieula). — 2. Echinorhinus (spinosus). — 3. Mo- 



nopterhinus (griseus). — 4. Galeorhinus (mustelus). — 5. Acanthorhi- 

 nus (acantheus). — 6. Heterodontes (Philippii). — 7. Carcharhinus 

 (Lamia). — 8. Cestrorhinus (Zygaena).— 9. Cetorhinus (Gunneri).
