diameter of eye. Dorsal and anal low; distance of origin of 

 dorsal from gillopenings about half the distance of gillopenings 

 from corner of mouth. Pectorals 4 4.5 times in length of head, 

 with ii 12 rays. Teeth acute, rather long, uniserial, on jaws and 

 vomer few in number, widely set ; on vomer about three, on 

 intermaxillary plate four (or more?) depressible teeth, somewhat

longer than the others. Gillopenings vertical, somewhat cres- 

 centic, slightly shorter than snout; about 25 branchiostegal rays 

 shining through the skin (see figure). Coloration uniform yellowish 

 gray with a silvery hue. Length 218 mm. [Type of the species 

 in the zoological Museum of Amsterdam]. 



Habitat: Java (Bay of Batavia), a specimen of 129 mm. 

 collected by Mr. P. BuiTENDljK. We found an other specimen 

 of 218 mm. in an old collection made by Mr. V. D. HUGT, 

 formerly secretary of the Government of Ambon and presented 

 by him to the Royal Zoological Society of Amsterdam. The 

 specimen is therefore most probably from the Moluccos.

Body scaleless, elongate, more or less compressed. Tail ending 

 in a slender tip or filament. Anus far behind gillopenings, in 

 anterior half of length. Lateral line present. Dorsal, anal and 

 caudal confluent. Pectorals absent. Snout elongate, pointed, 

 the upper jaw the longer. Nostrils superior or lateral, the poste- 

 rior slit-like, above or just in front of eye, the anterior tubular 

 or not, not far behind tip of snout. Tongue not free. Cardiform 

 bands of recurved teeth in jaws and on vomer; the lastnamed 

 not separated from those on the intermaxillary plate. Gill-
