INDIAN CYPRINID&. 237 
valent to eutting teeth ;* but in the Cirrhins even this is quite deficient. Nor 
does the analogy between these fishes and proboscidian quadrupeds end here ; 
the presence of cutting teeth implies a strong solid union of the two bony limbs 
‘of the lower jaw at the symphysis for their insertion, but in the Hdentates and 
Elephants the symphysis is remarkably feeble ; the two sides of the jaw being 
nearly separated by a deep fissure almost detaching its limbs from each other, 
as actually occurs in the Cirrhins, with which I include Labeos, which are also 
furnished with similar prehensile organs in the form of thick pendulous lips. 
So many corresponding circumstances between animals so remote from each 
other in the scale of affinity, cannot be referred merely to coincidence, but 
rather to a law of symbolical representation, by which the same type appears 
throughout an infinity of forms in the several classes. 
34. If Cyprinide be a rasorial group, as the above analogies of their most 
perfect forms with rasorial quadrupeds would seem to indicate, the same rela- 
tions should appear on contrasting them with other classes, the corresponding 
points becoming more striking or faint in proportion as the groups with which 
they are compared are contiguous or remote from them ; therefore, as birds are 
nearer to fishes than quadrupeds, the comparison of analogous types between 
these classes should afford more striking results than those I have cited. 
The most remarkable characteristic of rasoria] birds is their shortness 
of wing, terrestrial habits, and consequent strength and size of their legs, 
which are formed for the principal support of the body, and in some almost 
* Mr. Evans pointed out to me a peculiarity, for which he could see no object, in our skeleton 
of an Indian Rhinoceros, consisting of two minute incisors scarcely larger than those of a Rabbit, 
and hardly projecting from the alveolar; yet these teeth, so small as to be utterly unfit for any 
useful purpose, are found in every individual of the species. We can only regard these, and all such 
organs of which the animal kingdom presents innumerable examples, as the characters by which 
nature distinguishes her various types.
