FISHES OF NEW YORK 345 



sticklebacks in structure, but with prolonged snout and different 

 ventral fins. A single genus, with three species. 



The bony shields, characteristic of this genus, are the 

 following: 



1 A narrow strip along the median line of the back behind 

 the skull (confluent neural spines). 



2 The pair of broader lateral dorsal shields are peculiar bones, 

 separated processes of the occipital bone. These shields are the 

 longest, provided anteriorly with a ridge, which is prolonged 

 and extends far backward between the muscles of the back. This 

 ridge is flexible, and does not interfere with the lateral move- 

 ments of the flsh; it appears to serve as a base for the attach- 

 ment of muscular fibers. 



3 The narrow shield on the side is the postclavicle, its pos- 

 terior part being dilated and fixed to the lateral dorsal shields. 



4 The ventral shields are the interclavicles; their posterior 

 half is broadest, much pitted infeiiorly; they are narrower before 

 the middle, leaving a free lanceolate space between them, and 

 are again a little widened anteriorly, where they join the 

 clavicle and urohyal. These plates extend as far backward as 

 the ankylosed vertebrae. (After Jordan and Evermann)
