Schlegel's Sicydium obscurum is probably the same as Tridentiger 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 papillae below eye, continuous anteriorly with a row along 

 upper orbital edge. Two sharp dermal ridges extending posteriorly from tip of 

 snout as far as 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 coarselj^ punctate, with small brown dots. 



315. Leucopsarion petersi Hilgendorf. 

 Kobe, No. 6068a-b (Coll. Manabe).
