2. There are only seventy-three scales in the hiteral line. 



3. The anterior of the two nostrils is relatively lar<^er. 

 The scales of the lateral line are large, measuring as much 



as i inch in length. 



Ihe total length of the single specimen is 14 inches. 



In the middle and hinder parts of the fish, one inch of the 

 lateral line contains six scales, hut in the front these scales 

 overlap one another to a much further extent, so that one 

 inch contains eight or nine scales. 



In the anterior half of each scale of the lateral line is the 

 wide opening of its tube; the margin of this opening is 

 completed in front by a semicircular notch in the hinder edge 

 of the scale which lies next in front. 



Colour almost black ; head and lining of gill jet-black. 



One specimen, 14 inches long, from 1005 fathoms in the 

 (xulf of Oman. 



It is notable that N. pluriseri'alis (Gorm.), which this 

 species resembles in many ways, came from 1010 fathoms in 

 the Gulf of Panama. 



Rata PhiJipi, sp. n. 



The greatest breadth of the disk is equal to the greatest 

 length, including the ventral fins. 



The ends of the snout and tail are equidistant from the 

 c'loacal orifice. The snout is slender and prominent. The 

 interorbital space is 3§ in the length of the snout, measured 

 from an eye or the middle of the mouth. 



The anterior borders of the pectoral fins, which are some- 

 what sinuous, together form an angle of about 85°. 



The lateral angles are rounded. The spiracle is large, its 

 greatest diameter equals that of the eye. 



Numerous small spinules occur on the upper surface of the 

 tip of the snout and close to the antero-lateral margin in its 

 posterior half only. 



The superciliary ridge bears four spines in front and three 

 behind. 



There are five mid-dorsal spines in the branchial region. 



Between the ocellus and the margin of the pectoral fin is 

 a group of lanceolate denticles pointing inwards (probably 

 characteristic of the male). 



The whole lower surface of the snout is covered with fine 

 denticles. 



On the dorsum of the tail are three somewhat irregular 

 rows of spines. The tail is naked below, the sides of the tail 

 are spiny.
