V^hile lately (middle of September) using the large mid- 

 water net, which has proved so valuable in regard to the 

 life-histories of marine forms, a young wrasse, about 11 millim. 

 in length, was captured, which, from the length of the anal 

 fin and other characters approaches Lahrus mixtus, but appears 

 to be only a post-larval example of Lahrus maculatus, though 

 further examination is necessary on this point. 



This young wrasse shows boldly marked white touches on 

 a greenish ground variegated with brown pigment. The 

 general hue, indeed, is greenish brown with various bands and 

 patches. Thus the head has two white touches (each some- 

 what crescentric in form) over the brain, and a transverse one 

 in front of the dorsal fin. A brown band passes from the middle 

 of the eye forward on the snout and in line with the brown 

 bar on the tip of the mandible. Another brown bar extends 

 from the eye downward and forward, a third touch occurs on 

 the hyoid, and two or three bars exist elsewhere on the 

 head. The eyes are pale greenish with golden arches supe- 

 riorly, and a band of brownish red surrounds the pupil^ except 

 inferiorly, where it is almost absent. This reddish belt has 

 a process anteriorly and posteriorly. 



The body is conspicuously marked with eight white spots, 

 the first being near the pectorals, the last in the centre of the 

 base of the tail. These spots are situated above the lateral 

 line. Five opaque white spots again occur above the former, 

 two sending prolongations to the tip of the dorsal fin, and a
