Scales minute, lobate, ends in point behind, with 6 to 10 marginal 

 denticles. 



First dorsal inserted opposite inner hind angles of depressed pec- 

 torals, front edge 1% to 1% in head; second dorsal inserted nearly 

 opposite hind basal end of anal, front edge 5I/2 to 6 in head; anal 

 origin nearer that of subcaudal than ventral, front edge 4 to 4% 

 in head; subcaudal with front edge 2, or 2 in its own length; least 

 depth of caudal peduncle 5% to 6% in head; pectoral II/2 to 1%, 

 width 1% its length; ventral 2% to 3 in head. 



Gray above, under surfaces paler or whitish.

 Indochina, China, Formosa, Japan. This species seems to be well 

 figured by Day, though this is apparently overlooked or ignored by 

 Garman. Day says, "A w^ell marked groove at the angle of the 

 mouth extending on to both the upper jaw and along a portion of 

 the mandible," His figure shows this and agrees Avith my materials. 

 Garman says "labial folds short, extended more on the lower jaws 

 than on the upper." His Scoliodon intermediiis seems to differ in 

 that the "labial fold on upper jaw about two sevenths of its length, 

 that on lower jaw little shorter, partly hidden at angle." His dis- 

 tinction for Scoliodon toalheehmi that the "distance between outer 

 angles of nostrils and between them and end of snout about equal" 

 and for Scoliodon intermedms "snout rounded, length from nostrils 

 little less than the distance between their outer angles" is a variable 

 condition. Though my specimens all show the condition for Scoliodon 

 intermedins, Day's figure shows these proportions equal.
