178 ON SYSTEMATIC ZOOLOGY. 
that we deem it unnecessary to cite particular in- 
stances. The best, indeed, which the experienced orni- 
thologist can possibly have, is the preceding table of 
the series of genera, containing a full exposition of 
the ornithological system of the Régne Animal, which, 
except in the primary divisions, and with reference to 
the maierials possessed by each, is inferior to that of 
Linneus. 
228.) The Cuvierian arrangement of the Reptiles 
and Fishes need not be here enlarged upon ; for, inde. 
pendent of the space which the details of these divisions 
would occupy, our own arrangement of these classes 
will be nearly the same as that of the Régne Animal. 
With the class of insects M. Cuvier had no acquaint- 
ance, that having been entirely written by the celebrated 
Latreille, of whose system we shall subsequently speak. 
M. Cuvier’s great merit lies in the anatomical investiga-~ 
tion of those soft animals, placed by Linneus in the 
class of Vermes. Here his discoveries and observations 
are so original and valuable, that we feel assured the 
student will be desirous of seeing them noticed some- 
what more in detail. 
(229.) II. The Motxusca, with M. Cuvier, form the 
second of his great divisions of the animal kingdom ; 
and he divides them into the six following classes : — 
1. Cephalopoda, or cuttle-fish ; 2. Pteropoda, or wing- 
footed Mollusca ; 3. Gasteropoda, or univalve shell- 
fish ; 4. Acephala, or bivalve shell-fish ; 5. Brachiopoda, 
or parasitic shell-fish ; and, lastly, 6. the Cirripeda, or 
barnacle shell-fish. The following table, which enu- 
merates most of the family groups, will give a good 
idea of the system pursued : — 
OrpneER I. CEPHALOPODA. Cuttle- Ammonites, 
Jish. Nummulites. 
Sepia Z. 
Loligo Lam. Ozper II. ITERopopa. 
Nautilus Lam. Clio. 
Belemnites. Cymbulia,
