is called white-bone porgy, and the small Calamus arctifrons 
the grass-porgy. 
The Chopa spina, or pinfish, Lagodon rhomboides, is a little 
porgy with notched incisors, exceedingly common on our South 
Atlantic coast. 
In some of the porgies the front teeth instead of being canine- 
like are compressed and truncate, almost exactly like human 
incisors. These species are known as sheepshead, or sargos.
