ASTRABE LACTISELLA Jordan and Snyder. 



Misaki and Tanegasliima pools. 



Four specimens closely resembling the type were taken at Misaki. 

 A broad flap of loose, naked skin extends along the sides of the base of 

 both dorsal and anal fins. One specimen only was taken at Tane- 

 gashima. It is somewhat more slender than those from IVIisaki and 

 a little lighter in color. In life the spots on the head and fins were 

 bright orange; those on body pale lemon yeUow, except the one 

 extending across base of pectoral which was white; dark areas, deep 

 brown. 



CLARIGER COSMURUS Jordan and Snyder. 



Hakodate, Aikawa, and Msaki pools. 



Thirty specimens were secured at Misaki. They agree closely with 

 the type, except that in some individuals the lateral stripe is some- 

 what wider, and there are occasionally 11 rays in the dorsal and 

 anal, the usual number being 12. A more careful examination of 

 the teeth than was possible with the single type specimen shows 

 that they are arranged in two series, an outer single row of stronger 

 teeth which gradually increase in size posteriorly, and an inner broad 

 band of weaker teeth, the posterior of which are larger than the others. 

 In the upper jaw the posterior teeth of the upper band are almost as 

 large as those of the outer row, while the others are very minute 

 and weak. In the lower jaw of some specimens the most posterior 

 tooth is somewhat larger than the others. 



Individuals from Aikawa are somewhat Ughter in color than the 

 others.

Clariger exilis Snyder, Proc. U. S. Nat. Mus., vol. 40, 1912, p. 544. 

 Ten specimens from Tanegashima range in size from 20 to 32 milli- 

 meters in length. They were found in the more outlying pools and 

 appeared only after the water had been thoroughly poisoned.
