1 1'bc. fifteen spined Stickleback or Great Stickleback. 

 This fish, which is the largest species of the sticklebacks, 

 is slender, being only an inch thick, and nine in length: 

 the snout is long ; and the body of a pentagonal figure 

 towards the tail, which is flat, the mouth is small, and 

 the upper jaw projects beyond the lower. Tne gills and 

 the bony plate on the belly are brown upon the upper 

 part, silvery and streaked upon the lower. It has two 

 pectoral fins, one dorsal, rising in a triangular form from 

 the middle of the back: between this and the head are 

 fifteen distinct spines inclined towards the tail, which, 

 when depressed, are insensible to the touch. The fins 

 of the belly consist of two spines, the foremost of which 

 is the longest. In the fin at the anus there is also a 

 covered spine, but the other fins are soft and ramified. 

 The fifteen-spined sticklebacks, like the last mentioned 

 species, are found in the Baltic sea and the German 

 ocean ; they are very common in Holland, and also near 

 Lubeck in the duchy of Holstein. M. Bloch says, that 

 their ordinary size does not exceed seven inches, and 

 that he has found small crabs in their stomach. The 

 great stickleback does not ascend the rivers like the other 

 kinds, never leaving the sea, where it is taken among 

 other fish. Large quantities are sometimes taken by 

 kindling a fire on the shore, which draws them in shoals 

 to the nets. A kind of lamp oil is extracted from them 



and slender ; the head terminating in a beak; 

 the fin covering the gills with ten rays; the 

 opening to the gills pipe- fashion, placed near 

 the pectoral fins; the tins of the back, the anus, 

 and the tail, united in one. 2
