Dinichthys gouldi, Newberry; X I- A specimen showing vertebral axis, 

 ventral armoring and bases of dorsal and of ventral fin. From the collection 

 of Dr. William Clark, Berea, Ohio. A V, Anterior ventral. C, Coprolite. 

 D F, Basalia of dorsal fin. H A, Haemal arch. H S, Haemal spine. L P V, 

 Left posterior ventral. X A, Neural arch. N C, Notochord. K P V, Eight

 (Traquair) of Coccosteixs). V F, Basalia of ventral fin (?). V G, Pelvic 

 girdle. V M, Ventro-median. 



(The plates L P V, R P V, and portions of C, 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 ) 



(The Plate is repeated from Vol. XV., Plate VII.)
