PLATE VII. 
Dinichthys gouldi, Newberry ; < }. A specimen showing vertebral axis, 
ventral armoring and bases of dorsal and of ventral fin. From the collection 
of Dr. William Clark, Berea, Ohio. AV, Anterior ventral. C, Coprolite. 
DF, Basalia of dorsal fin. HA, Haemal arch. HS, Haemal spine. LP Y, 
Left posterior ventral. NA, Neural arch. NC, Notochord. RPV, Right 
posterior ventral. U, Plates of unknown position ( perhaps posterior laterals 
(Traquair) of Coccosteus). V F, Basalia of ventral fin(?). VG, Pelvic 
girdle. VM, Ventro-median. 
(The plates L P V, RPV, and portions of ©, U and V F were attached to 
the right half of the concretion. They are here shown as if attached to the 
opposite half of the concretion : they thus appear in their actual position, but 
in reversed aspects. )
