the base of the dorsal and anal fins. Ventral fins composed of 1 spine and 5 rays. Minute 

 teeth in the jaws and on the vomer, none on the pahitine l^oncs. Branchiostegals 5; air- 

 bladder large. Pyloric appendages in small number. {Giintlwr.)

A Capros with upper and lower profiles of the snout concave, with small scales, with 

 strong spines in the dorsal and ventral fins. Adults usually brownish red ; young, some 

 grayish, others red approaching vermillion on the upper parts, silvery white below; iris 

 golden, with some red spots.

The Boarfish of English authors is said to be common in the Mediterranean, and lias 

 also been found in the waters of Madeira ; stragglers have a few times been taken on the 

 south coast of England and Ireland ; the French explorers found it at various depths from 

 30 to 175 fathoms in the Gulf of Gascogne, on the coast ot Morocco, Soudan, and Spain, 

 and on the Banc D'Arguin. It is one of those forms which, while more especially charac- 

 teristic of the shore fauna, descends into moderately deep waters adjacent, and is by 

 courtesy admitted to the deep-sea lists, e.specially since the other members of the same 

 family are characteristic deep-water forms, and, in the opinion of Dr. Giinther, but rarely 

 come to the surface.

Antigonia capros is a cosmopolitan form, first linowii from the mid- Atlantic, off Bar- 

 bados and Madeira; since obtained in Japan, near the Ki Islands and Manado. The 

 greatest depth at which it has been taken is 129 fathoms, off the Ki Islands.
