FAMILY XVII. HYPS#IDA&,* Srorer. 
The jaws of this family are provided with lips; the intermaxillaries and 
lower jaw are armed with minute, slender, and slightly recurved teeth, most 
abundant a short distance from the median line ; upper maxillaries destitute of 
teeth. The intermaxillaries form the borders of the mouth above, and extend 
nearly to its angles. No eyes to be seen on dissection. Body covered with 
circular scales, which are so imbedded in the cuticle as not to present free 
edges. No adipose dorsal. Intestinal canal shorter than the body ; stomach 
cylindrical, terminating posteriorly in a short triangular cul de sac ; pylorus 
situated near the posterior extremity of the stomach, has a distinct valve which 
projects into the cavity of the duodenum ; two short, pyriform ccecal append- 
ages open by distinct orifices on opposite sides of the intestine. Air-bladder 
cordiform, deeply cleft anteriorly. 
This family, which I have formed in a great measure from the dissection 
of the only known species (Amblyopsis speleus) by my friend, Jeffries Wy- 
man, M. D., published in Silliman’s Journal, appears to be more nearly 
allied to the Cyprinide than to any other family of the Malacopterygii. It 
differs, however, from it, in the existence of a cul de sac to the stomach, and
