The above works were all written by De Lamark, who, in the 
first, divided animals into, 1. Those with vertebre. 2. Those 
without vertebra. 
In the second work he has arranged animals into— 
J. AVERTEBROSA. 
* Apatuiques. Class 1. Infusoria. 2, Polypi. 3. Radiata. 
4, Vermes (Epixoarie ?). . 
** SensIBLEs. Class 5. Insecta. 6. Arachnides. 7. Crus- 
tacea. 8. Annelides. 9. Cirrhipedes. 10. Mollusca. 
IJ. VERTEBROSA. 
#** INTELLIGENS. Class 11. Pisces. 12. Reptilia. 13. Aves. 
14, Mammalla. 
In his last work he proposed to have followed this arrangement ; 
but in the supplement to the first volume (which is principally oc- 
cupied with a second edition of his Philosophie Zoologique in the 
form of an introduction) he has thus arranged animals, with two 
additional classes :— 
Tnarticules. Articulés,
