JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 291 
Schlegel’s Sicydium obscurum is probably the same as T'ridentiger squami- 
strigatus of Hilgendorf, with which Jordan and Snyder have identified it. The 
description fits the Sicyopterus almost equally well, and the drawing diverges from 
both. 
314. Clariger cosmurus Jordan & Snyder. 
Misaki, No. 6075a-b. 
A double row of papillze below eye, continuous anteriorly with a row along 
upper orbital edge. Two sharp dermal ridges extending posteriorly from tip of 
snout as faras eye. Double serrated folds diverging from tip of lower jaw. Nasal 
tubules prominent. Two pairs of longitudinally set dermal flaps on tip of lower

jaw, one behind the other, these not true barbels, but parts of the dermal folds. 
Median line of body with about twenty-five pores. Scales in four or five rows on 
caudal peduncle, one row extending forward to middle of dorsal. Second and third 
dorsal spines wide-set. 
This rare species is one of the most peculiar among the gobies. Its color- 
pattern is variable, the opposed saddles on caudal peduncle very shallow in young; 
lateral stripes along body much narrowed; caudal nearly plain dark; eight spots 
along upper edge of stripes in one adult, in the other represented by a ragged edge; 
white areas coarsely punctate, with small brown dots. 
315. Leucopsarion petersi Hilgendorf. 
Kobe, No. 6068a—b (Coll. Manabe). 
Fie. 65. Leucopsarion petersi Hilgendorf. (From Proc. U.S. N. M., Vol. XXIV, p. 126). 
316. Luciogobus elongatus Regan. (See Fig. 66, p. 292). 
Misaki, No. 6052a; Lake Biwa, No. 6226a-g.
