DESCRIPTION OF A NEW SPECIES OF BLENNY FROM JAPAN. 
By HUGH M. SMITH. 
Among the miscellaneous zoological collections made by the Fish Commission 
steamer Albatross on the coast of Japan in 1900 is a small blennioid fish belonging to 
a species not heretofore met with by ichthyologists and representing a new genus. 
The specimen was dredged at a depth of 67 fathoms, at the head of the Suruga Gulf, 
island of Nipon. 
ETJLOPHIAS, new genus of Blenniidse. 
Generic diagnosis: Body very elongate; dorsal fin low, extending entire length 
of body and consisting of numerous rigid spines succeeded by a few simple rays; 
anal tin long and low, composed of one spine and numerous simple soft rays; caudal 
fin small but distinct, blended with the dorsal and anal; pectoral fins short and 
pointed; ventral fins absent; scales absent; no lateral line; gill membranes broadly 
united, free from the isthmus; nostrils tubular; ventral opening in advance of middle 
of body. 
Eulojphias, from t v, well; Ao^zag-, one having a bristly back; in allusion to the 
very long spinous dorsal fin. 
Eulophias tanneri H. M. Smith, new genus and species. (Enlarged about 2^ times.) 
This genus falls within the limits of the heterogeneous family Blenniidoe , but 
must there be placed in a separate subfamily (Ealophiasince) based on the very 
elongate form, the shape and size of the pectoral fins, and the few soft rays in the 
dorsal fin, combined with the presence of a pre-anal spine and the absence of a 
lateral line. 
This genus seems to be nearly related to no other genus. From Gebedichthys 
(represented by a single species from the Pacific coast of the United States), which 
it appears most closely to resemble, it differs in being much more elongated, with 
lower fins, more numerous dorsal soft rays, more anterior origin of the dorsal and 
anal fins, absence of lateral line, absence of a prominent longitudinal cephalic crest, 
etc. From Neozoarces , the type of which is from Okhotsk Sea, this genus may be 
distinguished by its more slender form, the presence of a caudal fin, the absence of a 
tentacle above the nostril, etc.
