appear as if covered with blood, when the fish is 
suddenly darting through the water, with this spine

This species I also received from Mr. Russell, 
who found it with the preceding. The general de- 
scription of the “pungitius”? answers to this species 
—but the appearance of the two varies in some

Length of species two inches and three lines; 
greatest depth two lines. Color grayish, with from

After death, this and the preceding species be-

measure disappear, and the careless observer would
