Three specimens from Mororan, Japan, collected by Jordan and 

 Snyder, have the gill-rakers on the eyed side in each case 4+10; 

 2 specimens on the blind side have 4 + 10, the third 4+12. The 2 

 larger specimens collected by the Albatross have a few rudimentary 

 gill-rakers on the anterior end of the lower arch, increasing the num- 

 ber on the eyed side to 4+12 or 13, on the blind side to 4 or 5+ 13 

 or 14; 1 specimen has other rudimentary gill-rakers between the 

 developed ones on the lower arch. If these are counted, the num- 

 ber becomes about 4+18. 



The 6 longitudinal rows of bony tubercles are less evident in the 

 larger specimens than in the smaller, or in Jordan and Snyder's 

 specimens from Mororan, 1 of which is figured by Jordan and Starks. 



This species has a long dorsal branch to the lateral line, the pores 

 on the eyed side opening on large papillae, those on the blind side 

 present, but usually filled with mucus, rather difficult to see. 



MICROSTOMIA STELLERI Schmidt. 



Microstomus stelleri Schmidt, Pise. Mar. Orient., 1904, p. 247. — Jordan and 

 Starks, Proc. U. S. Nat. Mus., vol. 31, 1906, p. 225. 



Albatross stations 4807 and 4808, Tsugaru Strait, between Hondo 

 and Hokkaido (Yezo). 



Albatross station 5031, Yezo Strait, northeast of Hokkaido 

 (Yezo). 



Albatross station 5041, off south coast of Hokkaido. 



Lower pharyngeals slender, as in M. MtaJiarae and in Limandaj 

 with two rows of conical teeth. 



The young are beautifully colored, as shown by two young speci- 

 mens from Albatross station 4808, and one collected at Hakodate by 

 Jordan and Snyder. A large dark spot on the lateral line just be- 

 hind the pectoral and another between this and the base of caudal 

 are ocellated with light (probably yellow in life), each of these spots 

 surrounded by a pale area; about Hre large pale markings along 

 base of dorsal, four along base of anal; dark mottlings below dorsal 

 in broad zigzag lines bordering the pale areas; base of caudal pale, 

 caudal darkly mottled; dorsal, anal, and pectoral of eyed side finely 

 mottled, other fins pale; body mottled elsewhere. Only traces of 

 these spots are found in adult specimens.
