3. MYXINE GARMANI Jordan and Snyder, new species. 



Mijxbie inhstralis GtiXTiiEH, Challenger Fishes, 1887, p. 2H7, not type, Hyalonema 



"Ground off Enoshima. 

 M(/xine sp. Garman, Deep Sea Fishes, 1900, p. 345. 



Teeth in upper series ten in number: the anterior three continent 

 at base but not enlarg-ed, rather narrow and not longer than the next 

 teeth; labruni or tip of snout above narrowly triangular, pointed at 

 tip, resembling the })arl)els. and searc-ely shorter than the barbel 

 standing next; pectoral pores about thirty; nasal barbels well devel- 

 oped, the upper somewhat shorter; buccal barbels prominent, the 

 iiuier pair short and thick, the lower longer than the rostral l)arbels. 

 Gill openings moderate, inserted a little before end of first third of body; 

 vent a little before middle of dorsal tin; anal scarcely as deep as borsal. 



Color dark purplish l)rown or plum color, slightly paler below; 

 barbels pale; dorsal and anal not edged with paler, no pale ridge 

 along back. 



Described from three specimens, the largest 19i inches long, in line 

 condition, the others injured, all taken oli' Misaki, where the species 

 is rather connnon. 



It was first noticed by Dr. Giinther who had half a dozen specimens 

 from the Hyalonema grounds oil' Enoshima. at a depth of 345 fathoms. 

 Dr. Giintber identities these specimens with Myxme australis eTenyns, 

 from Patagonia, and further ''believes" on rather scanty evidence 

 "that Ileptatreiiia drrhatnni of '^(^XAq^qX {Eptatretushurgeri) ^\\o\\\^ 

 be referred to the same species.'' 



As to this Mr. Garman very properly observes: "The results of 

 comparisons of representatives of the genus from other parts of the 

 world are such as to raise doubts concerning the specific identity of 

 the Japanese species with either of the species of ^fyxinc from other 

 regions.'' 



The Japanese form is in fact distinct, allied to M. trldentlger Gar- 

 man, from Sandy Point, Patagonia, in its dentition, and to M. acuti- 

 frons Garnian, from the same region, in the form of its labrum, or 

 front of snout. 



Named for Samuel Garman, of Harvard University, in recognition 

 of his excellent work on the species of Myxine.
