broad, maxillaiy reaching vertical from middle of e3^e. Teeth very 

 coarse, trilobed, the lateral lobes stout, nearly as long as the middle 

 lobe, the teeth arranged in broad bands, not decreasing regularly in 

 size outward; eight or nine oblique series in half of either jaw. GUI 

 opening extending down in front of three pectoral rays (in cotype, 

 the type mutilated). 



Origin of dorsal slightly behind base of pectoral ; the anterior rays 

 increasing gradually in length. Caudal rather slender, the tips of 



the rays coiled and apparently free, 

 its union with, anal equal to one-third 

 its length. Pectoral notched, the 

 lower lobe elongate, longer than the 

 -^^' " upper lobe, reaching nearly to the

Color in spirits, dusky, jet black anteriorly, where the peritoneum 

 and lining of the gill cavity show through. In life, the head, body, 

 and fuis rose red or brick red, brighter anteriorly, except where 

 underlaid by black. Pectoral blackish on inner face proximally. 



A well-marked species, distinguished in part by the very coarse 

 teeth and the elongate lower lobe of the pectoral.
