Distance of pectoral from snout (0.048 meter) 4 times width of interorbital area; its 

 length (0.029 meter) twice the lengtli of mandible. Insertion above the middle of the depth 

 of the body, on a level with center of orbit, its third ray loiigest, its tip reaching to vertical 

 from base of fourth anal ray. 



Insertion of ventral bchiiul pectoral and almost under tliat of first dorsal; its distance 

 from snout (0.053 meter) slightly exceeding twice its length (0.025 meter). Tip of ventral 

 filament reaches to base of tliird anal ray. 



Radial formula: D. ii, 11, 137; A. 120; P. 15; V. 7. 



Color: Ground color, light brownish gray; under parts, silvery; belly, darker, bluish. 

 Under surface of snout, pinlv, as is also the first dorsal except spines. Spines of dorsal, 

 ventral and anterior anal rays, blackish. Throat, branchiostegal membrane and isthmus,

The species was dedicated to Prof. Spencer F. Baird, and was tlie first deep-sea fish 

 obtained by the Fish Commissiou or described by an American ichthyologist. It ranges 

 from 150 to 1,255 ftithoms. 



This species is distinguished by Giinther from his Macrnrus wqualis, which it closely 

 resembles, (1) by its longer snout, which is nearly equal to the diameter of the eye; and (2) 

 the smaller number of the ventral rays (7).
