DISCUSSION OF SPECIES AND THEIR DISTRIBUTION. 247 



that of the first; the length of the third (22 millimeters) is about one-third the length of the 

 head; the fourth is about eijual to the third, the fifth is broken off, the sixth is slightly 

 shorter than the third, and the rest decrease gradually in size to the penultimate spine, 

 whose length (11 millimeters) is a little more than one-half the length of the last (19 milli- 

 meters). The longest ray of the soft dorsal (20 millimeters) equals one-half the length of 

 the base of the spinous dorsal. Length of the middle caudal rays (32 millimeters) is nearly 

 one-half the length of the head. The caudal is slightly rounded when expanded. The 

 anal origin is under the last spine of the dorsal. The length of the anal base (17 millimeters) 

 e([uals one-half of the postorbital part of the head. The spines are all stout, the length of 

 the first (10 millimeters) is about one-half of the second (21 millimeters) and exactly one- 

 half of the third (20 millimeters.) The length of the longest ray (2-4 millimeters) is about 

 one third the length of the head. The ventral does not quite reach to the vent; its length 

 (31 millimeters) slightly greater than that of the maxilla. The pectoral extends to the verti- 

 cal from the tenth spine of the dorsal. It reaches, also, to above the vent. It has the 

 lower 8 or 9 rays simple ; the first ray, also, is simple, and the intervening 13 rays are 

 divided. 



liadial formula:— U. xii, 9; A. iii, 5; V. I, 5; P. 23. 



Scales in 8 rows between the origin of the second dorsal and the lateral line, and in 15 

 rows from the origin of the anal upward to the lateral line. About 35 tubes in the lateral 

 line. About GO rows of scales can be counted from the upper angle of the gill-opening to 

 the caudal. 



Color (in alcohol) light orange yellow ; a faint dusky blotch on the upper part of the oper- 

 culum. An irregular area of dusky under the second half of tlie spinous dorsal extending 

 downward about to the middle of the body; another ill defined blotch two-thirds as long as 

 the eye on the basal half of the soft dorsal. The membrane of the spinous dorsal beginning 

 behind the foui'th sx)ine is vaguely intermingled with dusky. 



The type of the description is an example measuring 150 millimeters to base of caudal.

The greatest height of the body (32 millimeters) is about one- third of the standard 

 length. The least height of the tail (9 millimeters) equals one-half the length of the third 

 dorsiil spine and nearly one-half the length of the maxilla The length of the head (38 

 millimeters) equals the length of the base of the spinous dorsal. 



The greatest width of the liead (21 millimeters) equals one half its length without the 

 postorbital part. The width of the interorbital area (8 millimeters) is half the length of 

 the liostorbital part of the head. The length of the eye (15 millimeters) is contained 2§ 

 times in the greatest length and times in the standard length. The supraocular ridge is 

 elevated above the^ general profile, and the snout is abruptly declivous and very short; 

 its length (6 millimeters) is less than one-half the length of the eye. The maxilla reaches 

 to the vertical from the i)osterior nitirgin of the orbit, its length (20 niillimeters) is one-half 

 the length of the head and two-ninths of the standard length. The mandible reaches 

 behind the vertical from the posterior margin of the orbit; its length (22 millimeters) 

 equals nearly one-fourth of the standard length; it has a prominent knob at the symphy- 

 sis. The strong preorbital spines overhang the supra-uiaxilla. The nasal spines small. 

 Three spines at the top of the oi'bit, one in front and two behiTid. Two spines on each 

 side of the vertex and one on each side of the nape; a tympanic and a humeral spine. 

 Two spines on the operculum and five behind the border of the preoperculum, the first 

 with a small supplementary spine at its base. Suborbital carina feeble, with three small 

 spines. Top of head seal eless; si<les of head incomi)letely scaled. Cephalic filaments all 

 small, the longest one above the orbit about one-third as long as the eye. Six gill rakers 

 above the angle and seven below. The distance of the spinous dorsal from the snout (37 

 millimeters) equals the length of its base. The length of the first spine (7 millimeters) is
