seale: new species of apodal fishes. 89 



depth at anal pore 2.5 in head; the tail is but little longer than head 

 and trunk. 



Head moderately pointed, its length in total 9.3; in trunk 4; 

 mouth rather wide, the lower jaw somewhat curved, so that probably 

 in life, the jaws do not close completely; length from tip of snout to 

 angle of jaws 2.1 in head. 



Teeth in maxillary biserial, the outer row of twenty sharp com- 

 pressed teeth directed backwards, the inner row of four larger conical 

 teeth; premaxillary with six large canines plus four or five small 

 teeth pushing up among them. Vomer with large canines anteriorly, 

 plus a single series of six short, thick, but pointed teeth on the shaft; 

 mandible with teeth in a single series of fourteen acute teeth on sides, 

 plus two interior canines forming the inner series in front. Snout at 

 its posterior base about as wide as high; its length 5.5 in head. 



Anterior nostrils in short tube near tip of snout; these are scarcely 

 equal to length of pupil; posterior nostrils with a short tube or rim, 

 distinct, but might be easily overlooked without a lens. The nostril 

 is located above the anterior margin of eye. The eye is 1.5 in snout 

 and is located mid-way between angle of jaws and tip of snout. 



Lateral line and mucous pores not distinct. 



Gill-openings slightly larger than eye and located on middle of sides. 



No pectoral fin; dorsal and anal fins distinct but not especially 

 elevated, they meet around the end of tail; origin of dorsal directly 

 above the gill-openings. 



Color in alcohol: — uniform seal-brown, fins darker, without any 

 white margins; black at angle of jaws and at gill-openings; the fins 

 when the specimen was first received, according to a note, were green. 



Total length 211 m.; to anal pore 93 m.; length of tail 118 m.; 

 length of head 23 m. 



Type.— M. C. Z. 6146. Mauritius. Nicholas Pike. 



Mauraena acutis, sp. nov. 



Body elongate, cylindrical, somewhat compressed, the head rather 

 sharp pointed, the jaws of equal length, tail evenly compressed from 

 the anal pore to tip; dorsal and anal confluent. The length of the 

 head and trunk slightly greater than tail; head 2.75 in trunk and 7 

 into total length. Mouth of moderate size and closing completely; 

 the under jaw being strongl}' curved ; length from tip of snout to angle 

 of jaws 3 in head.
