III. DESCRIPTION OF A NEW SPHAGEBRANCHUS FROM 

 THE BAHAMAS. 



(Plate IX.) 



By C. H. Eigenmann. 



The genus Sphagebranchus is characterized by the absence of all 

 fins and the small inferior gill-slits. Snout very sharply pointed, 

 mouth large, horizontal, inferior, the lower jaw sharply pointed; 

 gular region somewhat expanded, and with longitudinal grooves; 

 gills large, gill-slits small, converging forward along the inner edge of a 

 pair of comma-shaped depressions, the bottom of the depressions with a 

 thin membrane ; -nostril inferior, not completely divided into anterior and 

 posterior; lateral-line pores prominent. About twenty-three recurved 

 teeth in the lower jaw, about twenty-seven similar teeth in a compact 

 row along each side of the upper jaw, those in front smallest, four 

 similar, but much larger, teeth on the snout in front of the regular 

 series; about ten recurved teeth on a median line in the roof of the 

 mouth. No tongue. 



Sphagebranchus conklini sp. nov. 



6710, C. M. Type, 235 mm. From coarse sand in ten feet of water, 



just inside the bar at entrance to harbor, New Providence, Bahamas, 



April 27, 1907. Collector, E. G. Conklin. 



Tip of snout to anus 88 mm., to gill-opening 18; tail 147 mm.; gape 

 of mouth 4 mm.; snout to eye 3.3 mm.; eye .66 mm.; width of body 

 4 mm. Over no pores in the lateral line; eye covered, but visible, 

 the pupil a horizontal slit. 



This species is evidently related to S. anguiformis Peters, the type 

 of which was taken in the open Atlantic 15° 40' i" north, 23° 5' 8" 

 west. The location of Nassau is 25° 5' 6" north and 77° 21' 2" west. 

 The differences may be tabulated as follows:
