FAMILY XVII. HYPS.EIDiLV Storee. 



The jaws of (his 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 dc 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 spekus) by my friend, Jeffries Wy- 

 man, M. D., published in Silliman's Journal, appears to be more nearly 

 allied to the Cyprinidce 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
