189I.] NEW-YORK MICROSCOPICAL SOCIETY. 93 



" The Pipe-fish, Sytignathus aciis, belongs to the Teleostei, or 

 bony fishes. It is the most common and widely propagated fish 

 of its family. The body is cylindrical, laterally compressed, and 

 covered with a mailed skin. The elongated, tubular snout has 

 no teeth, and opens in front at the top. There are four tufts of 

 gills on each side, and the gill-openings are narrow. The males 

 have brood-pouches on the abdomen. The dorsal fin shows 

 forty rays, but the pectoral and anal fins are small. The tail 

 appears like a fan on a long handle at the end of the long body. 

 Thus the propulsion of the fish is done mostly by the undulating 

 movements of the dorsal fin. The Pipe-fish is found between 

 ^-. -weeds at the bottom of shallow waters, and feeds on small 

 c astaceae and worms."
