Dorsal, 65; anal, 53; pores, 80. Another specimen from Ebisu, 

 Dogo Island. 



This species is possibly the same as L. schrenki Schmidt (misspelled 

 L. schrencki by Jordan and Starks). L. herzensteini Jordan and 

 Snyder, is a very doubtful synonym. 



Genus LIOPSETTA Gill. 



Liopsetta Gill, Proc. Acad. Nat. Sci. Phila., 1864, p. 217 (glaber=putnami). 

 Euchalarodus Gill, Proc. Acad. Nat. Sci. Phila., 1864, p. 222 (putnami). 



This genus differs from Limanda in the broad appressed pharyn- 

 geals, with blunt teeth, and in lacking the semicircular arch in the 

 lateral line, although a high curve may be present. Liopsetta is also 

 very close to Pleuronectes , but that genus has a single row of teeth on 

 each side of the lower pharyngeals. The males of all known species 

 have much rougher scales than the females. Difference in the char- 

 acter of the lower pharyngeals and of the arch in the lateral line seems 

 to separate two natural groups, which are here described as subgenera. 



GARETJS, new subgenus. 



This subgenus includes only Liopsetta obscura (Herzenstein) and is 

 characterized by the high curve in the lateral line, its height about 

 five in straight part, and by the broad lower pharyngeals, closely 

 appressed for half of their length, each side with two rows of large 

 blunt teeth. 



Type of the subgenus. — Pleuronectes obscurus Herzenstein. 1 



" Garei " is the Japanese word for flounder. 



LIOPSETTA Gill. 



This group includes Liopsetta glacialis, L. putnami, and L. pinni- 

 fasciata. It may be characterized by the straight lateral line, and 

 by the massive lower pharyngeals, closely appressed for more than 

 half their length, and nearly triangular in form, the blunt teeth of 

 which are arranged on each side to form an inner, an outer, and an 

 upper row, with one or more series between these. 



LIOPSETTA OBSCURA (Herzenstein). 



Pleuronectes obscurus Herzenstein, Melanges Biologiques, 1890, p. 127. Che- 

 mulpo; Vladivostok. 



Liopsetta obscura Jordan and Gilbert, Rep. Fur Seal Invest., vol. 3, 1898, p. 

 492.— Jordan and Starks, Proc. U. S. Nat. Mus., vol. 31, 1906, p. 217. 



This species is superficially very similar to Limanda yolcoJiamae, 

 the low arch of that species closely approaching the high curve of 

 Liopsetta obscura. The long, slender pharyngeals in the former 

 species (as usual in Limanda) not being appressed, and with two 

 rows of conic teeth, easily separate it from Liopsetta obscura.
