mens examined, 3 inches long, have 17 hnes between the pectorals; 

 a specimen 5 inches long has 10 lines; and the largest specimen 

 examined, 10 inches long, has 12 lines."" My larger example, 155 

 mm. long, has 21 lines between the pectorals; the smaller example, 

 132 mm. long, has 10 lines between the pectorals. Their general 

 color-pattern is similar, even to the disposition of the black blotches, 

 though these are quite variable, likewise the armature. The fins 

 are pale or whitish, and uniform in color.
