of Aplodactylus live on the coasts of Chile and Australia. They 
are herbivorous fishes, with flat, tricuspid teeth, and except 
for their pectoral fins are very similar to the Kyphoside.

The San¢dfishes: Trichodontide.—In the neighborhood of the 
Latridide, Dr. Boulenger places the Trichodontide or sandfishes, 
small, scaleless, silvery fishes of the northern Pacific. These

are much compressed in body, with very oblique mouths, with 
fringed lips and, as befits their northern habitat, with a much 
increased number of vertebre. They bury themselves in sand 
under the surf, and the two species, Trichodon trichodon and 
Arctoscopus japonicus, range very widely in the regions washed 
by the Japan current. These species bear a strong resemblance 
to the star-gazers (Uranoscopus), but this likeness seems to be 
superficial only.
