Eulophias tanneri, new species. 
Body elongate, eel-like, cylindrical anteriorly, compressed posteriorly; tapering gently back- 
ward and terminating in a blunt point; greatest depth about 0.05 total body length. Head rather 
long, conical, not larger than body, its length 0.12 body length, terminating posteriorly in a rounded 
flap. Eye large, directed slightly upward, rather less than 0.33 length of head; interorbital space con- 
tracted, not wider than pupil. Snout short, rounded, 0.5 length of eye. Mouth rather large, terminal 
slightly oblique, jaws equal, maxillary extending to vertical of anterior edge of pupil; nostrils tubular, 
midway from eye to end ox snout; gill membranes broadly united, not attached to isthmus. Anal 
orifice 0.4 distance from snout to end of body. Dorsal fin low, continuous, beginning slightly in 
advance of posterior edge of opercle and extending to caudal fin, gradually increasing in height from 
before backward; composed of 121 stiff spines and 13 simple soft rays; anal fin long and low, begin- 
ning under thirty-sixth dorsal spine and extending to caudal; consists of 1 spine and about 75 simple 
rays, the length of the spine being about twice that of the adjoining rays; caudal fin blended with 
dorsal and anal, composed of 7 simple rays; pectoral fins short, pointed, and narrow, less than half 
length of head. Length of specimen, 45 mm. 
Colors: Underparts whitish; a series of brownish elongated blotches, about 20 in number, extends 
along side from head to tail; above these a series of smaller blotches of same color, about twice as

Type (No. 49798, U. S. National Museum) collected by Albatross, in about 67 fathoms, at station 
3715, in Suruga Gulf, Japan, May 11, 1900. 
This interesting species is named for Commander Z. L. Tanner, U. 8. N., com- 
mander of the Fish Commission steamers Albatross and Fish Hawk from 1879 to 
1894, the foremost exponent of the methods of modern deep-sea exploration, whose 
intelligent and zealous investigations have led to most valuable contributions to 
oceanic biology and physics.
