 Head 3|; depth 2f; D. I. -i!!; A. 51, Body oblong, much com- 

 pressed, and skin with a lino velvety touch. Head very deep, convex 

 both above and below; snout slightl}^ produced upward; eye small, 

 not much above the mouth, 5 in snout, 5| in head, If in space between 

 its upper margin and origin of spinous dorsal, and 1 in space between 

 its lower margin and upper margin of gill opening; teeth broad, emar- 

 ginate, the middle mandibular pair pointed; lips thin and narrow, 

 smooth; nostrils small, in front of upper part of eye; gill opening 

 rather long, oblique forward till a little anterior to the nostrils, 2f in 

 snout and equal to pectoral; origin of spinous dorsal over the anterior 

 edge of eye, and midway })etween the tip of the snout and the origin 

 of the soft dorsal; soft dorsal and anal with the anterior rays the 

 longer, the longest in both of the lins equal; caudal damaged; pectoral 

 inserted below the mouth and a little behind the middle of the eye; 

 caudal peduncle compressed, equal to one-third the distance from 

 posterior margin of eye to tip of snout. 



Color, in alcohol, uniform brown, mottled with darker, and the lins 

 all plain-colored and pale. Here described from a specimen lOi inches 

 long, obtained by Professor Otaki in the market at Toln-o. Tropical 

 seas, ranging widely, recorded from Cape Cod, throughout the East 

 and West Indies, and from Nagasaki in Japan, where it must be rare. 

 The original Alutera monoceros came from China. The American 

 species, Alutera guntheriana Poey, will ver}^ likely prove different.

14. OSBECKIA Jordan and Evermann. 

 OshecUa Jordan and Evermann, Check List Fishes N. A., 1896, p. 424 (scrlpla). 

 This genus is very close to Alutera, differing in the longer snout, 

 concave anterior profile, and very long caudal fin, in which the outer 

 rays are much shortened. Size large. From the American genus, 

 Ceratacanthtis, a very near relative, OshecMa difi'ers in the longer 

 dorsal and anal fins, there being about 36 rays in Ceratacanthus. 



(Named for Per Osbeck, a pupil of Linnseus and an excellent natu- 

 ralist, who explored the coasts of China about 1750.)
