seale: new species of apodal fishes. 83 



series of graduated teeth extending back on the shaft. MancHhuhir 

 teeth uniserial, of about fourteen conical teeth of moderate size. 



Snout 4.9 in head; anterior nostril in tul)e shghtly anterior to tip 

 of lower jaw; posterior nostril a slit on under side of upper lip, on a 

 line with anterior margin of eye; the eye is mid-way between tip of 

 snout and angle of jaws, its length 1.7 in snout. 



Gill-openings large, slit-like located low on the sides, their openings 

 but little less than their distance apart. Lateral line is distinct, but 

 pores not obvious. Dorsal and anal fins low but distinct; the pectoral 

 is microscopic, easily overlooked, its length less than e^e, represented 

 by a small membraneous flap; origin of dorsal posterior to gill-open- 

 ing by a distance contained 4 times into head. The dorsal and anal 

 end very near the tip of the tail. 



Color in alcohol: — body grayish with nineteen or twenty wide black 

 bands over the back extending down to the lateral line; the bands 

 as wide as the interspaces and alternating with large round black spots 

 on the sides below the lateral line. A black bar over the head and 

 through the eyes like a mask, a yellowish space in front and behind 

 this mask; cheeks and top of head with large black spots ocellated with 

 whitish; lower jaw with fine black specks, nuchal region with, the first 

 black bar. A few black dots on upper lip and on tip of snout; ven- 

 tral surface and fins uniform. 



Total length 595 m.; length to origin of anal fin 327 m.; to origin 

 of dorsal 58 m.; length of head 53 m.

Quassiremus parvipinna, sp. nov. 



This species has distinct, but low dorsal and anal fins. The ante- 

 rior nostril is in a tube near the end of the snout. Teeth all pointed ; 

 maxillary teeth uniserial, twenty-one, sharp, pointed, compressed, 

 becoming smaller posteriorly; premaxillaries uniserial, consisting 

 of five backwardly directed, conical, sharp, curved teeth, the largest of 

 the upper jaw. Vomer with a cluster of four large sharp teeth ante- 

 riorly, plus a single series of fine small rounded teeth on the shaft. 

 Lower jaw uniserial with about twenty-one curved conical teeth of 

 moderate size. Origin of dorsal posterior to gill-openings. The 

 pectoral fin is reduced to a small flap about equal to ^ length of eye. 

 Gill-openings lateral. Head in total length 12.1; head in trunk 5.
