DISCUSSION OF SPECIES AND THEIR DISTKIBL'TIOX. 247 



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

 head; the fourth is about equal to the third, the tifth is broken oft', the sixth is slisihtly 

 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 tlie last (I'.l milli- 

 meters). The longest ray of the soft dorsal (2(i millimeters) ('(juals one half the length of 

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

 one-half the h'ugth 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) 

 equals one-half of the postorbital part of tlie head. The sjiines 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 (24 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 tlie 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. 



Kadial formula: — D. xii, 9; A. iii, 5; V. i, 5; P. 23. 



Scales in S 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 3,~) tubes in the lateral 

 line. About 00 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 theoper- 

 culuni. An irregular area of dusky under the second half of the 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 fourth spine is vaguely intermingled with dusky. 



The type of the description is an example measuring l.")0 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 iniiiiuieters) ecpials one-half the length of the third 

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

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



The greatest width of the head (21 millimeters) e(iuals one half its length without the 

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

 the postorbital part of the head. The length of the eye (15 millimeters) is contained 2g 

 times in the greatest length and times in the standard length. The su])raocular ridge is 

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

 its length (0 millimeters) is less than ime-half the length of the eye. The maxilla reaches 

 to the vertical from the posterior margin of the orbit, its length (20 millimeters) 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 siipra-maxilla. The nasal spines small. 

 Three siiines at the top of the orbit, one in front and two behind. 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 i)reoperculum, the fir.st 

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

 spines. Top of head scaleless; sides of head incompletely 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 

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