366 REPORT OF NEW JERSEY STATE MUSEUM. 
Genus ‘T’RICHODIODON Bleeker, 
The Hairy Fishes. 
Trichodiodon pilosus (Mitchill). 
Balloon Fish. 
This differs from the other members of the family in the 
very small dermal ossifications, each of which is 2-rooted with 
a fine flexible spine or hair-like bristle. 
This species, very imperfectly understood, has been recorded by 
Dr. Abbott, who states that it is occasionally met with, a state- 
ment, however, which needs verification. Its capture within our 
limits is certainly to be questioned as yet.
