the membrane entire; ventral spine minute, the rays united by mem- 

 brane for about half their length, outer ray shorter than the inner. 



Color of female; body yellowish white, crossed by 6 nearlj^ vertical 

 dark brown bands, verj^ irregular in outline, not extending on ventral 

 surfaces, the first passing downward from between the first and second 

 spinous dorsals, behind liase of pectoral, the second below anterior 

 part of second dorsal, the third below the posterior part, the fourth 

 and fifth below the soft dorsal, the sixth near base of caudal; the first 

 to fourth bands more or less divided l\v light lilotches within their 

 boundaries; nape with a small poorly defined cross-l)and; head irregu- 

 larly blotched with brownish; first dorsal with elongate dusk}' clouds; 

 second dorsal with slightly oblique dusky bands anteriorlj-, which 

 branch and intercept, becoming reticulations posteriorly; spines and 

 rays of soft dorsal, anal, and caudal with alternating dusky spots and 

 clear spaces, appearing like oblique bands on the dorsal and anal and 

 vertical bands on the caudal; pectoral faintly clouded with dusky. In 

 the males the ground color is much darker except a narrow white 

 space behind the second and another behind the third dorsal fin, form- 

 ing vertical bands in liold contrast with the rest of the body. The 

 dark bands described in the female can easily be traced, though they 

 are not so prominent. The fins, except caudal, are nearly black, the 

 second dorsal narrowly edged with white, the soft dorsal and anal with 

 a large white spot on posterior ends. The caudal is colored as in the 

 female. The fins of the male are higher than those of the female, the 

 first dorsal spine al)out 2 in head, membrane with a broad, deep 

 scallop between second and third dorsal spines.

Table showing fin-ray and scale counts of seven specimens from 

 Misaki. 



We have many specimens from Misaki, 2 from Wakanoura, and one 

 from Atami, province of Izu. These beautiful little fishes are found 

 in the rock pools at the ends of the promontories. They cling close 

 to the rocks with their paired fins, even to vertical walls of cliffs.
