D. VII, 11; A. ca. 10. The head and body suborbicular ; the body posteriorly is 

 abruptly compressed. The mouth is moderate, the jaws with narrow bands of villifonn 

 teeth. The maxilla reaches to below the anterior margin of the eye, its length being 

 contained 2 times in that of the head. The gill opening is small, as long as the diameter 

 of the eye, which is contained 3 times in the length of the head. The disk is about as 

 long as it is broad, f of the length of the head. The interorbital width is greater than \ 

 the length of the head, and not quite twice the diameter of the eye. Length of head 

 contained 3 times, greatest height of body 2 times, in total length. The body is covered 

 with conical plates of various sizes, those of the pectoral region being the largest, about 

 as large as the eye. The plates are studded with small tubercles, and the larger ones 

 have the centers elevated and pointed. Color in spirits, light brown, with traces of 

 punctulations on the skin between the plates.

Head 2|; depth U. D. VII, 9; A. 10; caudal 10; branchiostegals 6. 

 Body compressed, thick, short, and high; head short, higher than wide, 

 flattened ; supraorbital angles prominent. In the specimen described, badly 

 shrunken by drying, the height of the head is contained in the distance 

 from the snout to the base of the caudal nearly twice. Eye large, about 

 34- times in the length of the head. Teeth numerous, small, subconical, 

 in pavement, 4 or 5 series. Anterior dorsal much as in a specimen of 

 C. lumpus of 3 inches in length, the sides of the fin covered with spines 

 of moderate size, the spinous rays 7 in number. The upper outline of 

 this fin is much like that of the Lump, in being arched backward, or 

 crescentic. The 10 rays of the second dorsal are very distinct; the 

 membranes are not so tuberculate as those of the first. Entire body and 

 head covered with spiny conical tubercles, the largest in a group of 7 or 8 

 on the flank behind the pectorals, another on the forehead, and those on 

 the supraocular ridge. A single large one stands at each side of the 

 space between the dorsals. Those on the flanks are in contact, and on an 

 example 4 inches in length there are several that exceed \ inch in diame- 

 ter. The sides of the tubercles are roughened by multitudes of fine sharp 

 spines. Under chin and throat the tubercles are smaller, close together, 

 and very numerous. The origin of the first dorsal is above and a little in 

 front of the gill opening. The latter is above the base of the pectoral, 

 behind the eye ; its width is hardly as great as that of the orbit. Profes- 

 sor Collett gives a good figure of C. spinosus; to compare the specimen 

 from which these notes are taken with it, the Pacific representative is 

 higher and more arched in front of and over the first dorsal, the depth of 

 the body is greater in proportion to the length, and the spines above the 

 lateral line, from the space between the dorsals to the back of the skull, 

 are a great deal smaller. These differences are such as may obtain on
