EEPORT ON THE DEEP-SEA FISHES. 25 



more differentiated from the soft. The scales are small; abdominal scutes ten. 

 The height of the body is. less than one-half of the total length without caudal; the 

 diameter of the eye two-ninths of the length of the head. No projecting suprascapulary 

 spine. The third and fourth dorsal spines are the longest, and the seventh is shorter 

 than the eighth. 



Only one specimen, 19 inches long, w\as obtained off Madeira in the month of April. 

 Mr. Johnson adds that from the protruded stomach and inflated membranes about the 

 eyes it may be inferred that the fish came from a great depth. Like so many other 

 Madeiran fishes, this species occurs also in Japan, where it was met with by Doderlein, 

 who seems to have been unacquainted with Johnson's description. 



Anoplogaster, Gthr. 



Body compressed and deep, covered with minute asperities ; abdomen without enlarged 

 dermal scutes; head large, with thin bones deeply sculptured to receive wide muciferous 

 cavities. Mouth very wide and oblique; jaws armed with bands of small teeth which 

 are somewhat larger and of unequal size in the lower jaw; no teeth on the palate. Eight 

 branchiostegals ; gill-openings very wide. Suprascapulary and angle of the prasoperculum 

 armed with a spine. One dorsal fin, without spinous division ; ventrals with six soft 

 rays. Air-bladder small, pear-shaped.

 Of this singular fish only very few specimens are known, and, with the exception of 

 one, all were taken from the stomachs of pelagic fish of prey, one in lat. 2G°, three in lat. 

 31° N. and long. 40° W., and one in lat. 25° N. and long. 31° W.; all in the Atlantic. 

 The largest of these specimens is only 77 mm. long. Lutken has made the interesting 

 observation that in very young specimens (10 mm. long), no ventral fins arc 

 developed, and that the spines on the head are much elongate, forming a very effectual 

 armature. 



Caulolepis. 



Caulolepis, Gill, Proo. U.S. Nat. Mus., 1884, vol. vi. p. 258. 

 Closely allied to Anoplogaster, which it also resembles in the form of the body. 

 Body covered with pedunculated leaf-like scales. A pair of very long teeth in front of
