these much larger and others gradually decreasing in size towards 

 rictus, where quite larger still than very small externals. Long teeth 

 uniformly larger in lower jaw, and when jaws close alternate so that 

 their tips fit in sockets in opposite jaw. Front of upper jaw with 

 4 rather small teeth in transverse series and mandible with 1 enlarged 

 tooth at each corner in front, also a smaller one unsymmetrically on 

 front of left ramus. Osseus palatine ridge externally with an elongated 

 narrow asperous area and along its inner edge a series of small pointed 

 teeth, much larger than asperities, though quite inconspicuous. An 

 inner elongated area of palatine asperities, becoming wider poste- 

 riorly. A narrow median area of vomerine asperities. Tongue broadly 

 expanded, free, deeply notched in front and upper surface well asper- 

 ous. Nostrils 2 small pores, lower inferior and posterior superior, 

 near snout tip, distance between anterior and posterior about 1^ 

 in anterior internasal. Interorbital broadly depressed, very slightly 

 convex. Opercle almost deep as long, and lower edge convexly 

 curved forwards. Bones of head all with rather conspicuous and 

 coarse rugosites or striae. 



Gill-opening forward about half-way to eye, forming rather broad 

 fold over isthmus. Rakers about 5 + 10 short rounded asperous 

 stumps, filaments about half of horizontal eye, and pseudobranchise 

 about f of filaments. Xo osseous scutes along inside edge of gill- 

 openings. 



Most all scales entirely smooth. Series of enlarged scales along 

 gill-opening above, and down to pectoral base, lower slightly roughened. 

 L. 1. nearly median along side, sloping down little low along caudal 

 peduncle side, and each scale in its course with slight notch at pos- 

 terior apex. 



Dorsal origin near last -^ in total length (caudal damaged) or about 

 opposite base of fifth branched anal ray. Anal similar, inserted well 

 before. Caudal elongate, rounded, and upper median rays appar- 

 ently (damaged) longest. Pectoral pointed, about 2\ to ventral. 

 Ventral trifle larger than pectoral, about 2 to anal, inserted about 

 midway between pectoral and anal origins. Vent close before anal. 



Color in alcohol uniform brownish, upper surface scarcely paler. 



Length 418 mm. (16^ inches).

The above is the only example I have seen, and seems to be most 

 closely related to Lepidosteus grayi Agassiz, which is said to have 

 smooth scales, snout not longer than rest of head, and a series of
