In another rather larger specimen, which agrees with that above 

 described, the lateral line is well preserved. 

 From the South Park, Colorado. 



Amyzon fusiforme, s}}. nov. — Eepresented by a very small fish, which 

 exhibits fully ossified bones, but may be immature. It exhibits characters 

 quite distinctive, although the caudal pednncle, anal fin, and opposite 

 parts of dorsal are wanting. The head is very perfectly preserved, and 

 is of a regularly short-conic form, with equal lips. The attenuated muz- 

 zle shows none of the obtuseuess characteristic of the other Amyzons. 

 Another peculiarity is seen in the ventral fins, which stand below the 

 eighth instead of the first articulated ray. They are evidently in their 

 normal position, and the ribs are undisturbed. The pectorals extend 

 more than half-way to the ventrals. There are seven neural spines in 

 front of the first interueural, and sixteen between the latter and the first 

 interhpemal. In this, as in the other species, the postclavicle is rather 

 elongate and acute, and the parapophysial element of the anterior ver- 

 tebral mass extends as far down as the line of the middle of the orbit.
