Under the name Diodon pilosus De Kay describes and 

 figures a specimen 2 inches long which he considered identical 

 with the Diodon pilosus of Mitchill, but which may be 

 the young of Diodon hystrix, a species not yet recorded 

 in New York waters.

Body broad, depressed, moderately inflatable. Dermal spines 

 short, stout, immovable, triangular, each with three roots; 

 nasal tube simple, with two lateral openings; the tube some- 

 times rounded, sometimes flattened, and with the partition 

 feeble and easily torn so that the tentacle appears divided; 

 caudal peduncle short; fins small, formed as in Diodon; jaws 

 without median suture. Species numerous, of smaller size than 

 those of Diodon, the spines broader and lower, their bases 

 forming a coat of mail.
