18 Dr. A. Giinther 07i Deep-sea Fishes 



ScylUum canescens. 



The nasal valves are separate from each other, the distance 

 between them being less than the length of a nasal opening ; 

 each is provided with a cirrus. Length of the prajoral portion of 

 the snout much less than its width or than the width of the 

 mouth. Labial fold very short. The posterior dorsal slightly 

 longer than the anterior. The anal terminates below the 

 middle of the second dorsal, its base being longer than that 

 of the latter fin and equal to its distance from the caudal. 

 Uniform greyish ; all the fins, except the caudal, tipped with 

 white behind. 



South-west coast of South America (Station 310), 400 

 fathoms. 



Bathydraco, g. n. Trachin. 



Body elongate, subcylindrical ; tail tapering ; head de- 

 pressed, with the snout much elongate, spatulate ; mouth wide, 

 horizontal, with the lower jaw prominent ; eyes very large, 

 lateral, close together. Scales very small, imbedded in the 

 skin. Lateral line wide, continuous. One dorsal fin ; ven- 

 trals jugular ; the lower pectoral rays branched. Teeth in 

 the jaws in villiform bands ; none on the vomer or the pala- 

 tine bones. Opercles unarmed; ten branchiostegals ; the 

 gill- membranes free from the isthmus and but slightly united 

 in front. Air-bladder none. 



Bathydraco antarcticus. 

 D. 36. A. 31. P. 23. V. 1/6. 

 ■ South of Heard Island (Station 152), 1260 fathoms. 



Haloporphyrus rostratus. 

 B. 7. D. 4 I 51-56. A. 38-39. V. 6. 



This species is readily distinguished by the peculiarly pro- 

 duced snout, which forms a short, triangular, pointed lamina, 

 sharply keeled on the sides, and overreaching the cleft of the 

 mouth. 



Deep sea, midway between the Cape of Good Hope and 

 Kerguelen's Land ; east of the mouth of Rio Plata. (Stations 

 146\and 320.) 600 and 1375 fathoms. 



This fish differs in some important points from Halopor- 

 phyrus, as the form of the snout, backward position of the 

 vent, imperfect division of the anal, in which latter respect it 

 approaches Mora ; therefore it may be regarded as the type 

 of a distinct subo^enus Antimora.
