The horseflsh inhabits the seas of tropical America, ranging- 

 from Maine to Brazil and from Lower California to Peru. In 

 summer it is sometimes abundant as far north as Saco Me,, and 

 at Woods Hole Mass., in Buzzards bay and Vineyard sound, but 

 sometimes it is rare in those waters. When present, it appears 

 in August and remains till September. The fish is also reported 

 in western Africa. Mitchill calls it the bristly dory. He records 

 it from New York bay. De Kay states that it appears in New 

 York waters in July and August, and that it is esteemed for 

 food. An individual was brought from Gravesend bay Oct. 21, 

 1896, and a young example, known there as dollarfish, was re- 

 ceived from the same locality Oct. 22, 1896. 



The species reaches the length of 1 foot. It is esteemed an 

 excellent article of food. It finds its way to New York in con- 

 siderable numbers every year but is rarely seen in other markets. 

 Nothing is known of its breeding habits. 



The horsefish has several additional common names: sunfish, 

 jorobado (Cuba), blunt-nosed shiner, pug-nosed shiner, and hump- 

 backed butterfish.
