MYOXOCEPHALUS ENSIGER (Jordan and Starks.) 



. Several examples of the young of this species were collected in 

 the pools at Hakodate by Jordan and Snyder and also by members of 

 the Bureau of Fisheries steamer Albatross expedition. Tliey measure 

 about 80 miUimeters in length. In life they were briUiant in color, 

 like the coralline algre, with three dark bands passing over the body; 

 the first crosses the back beneath the spinous dorsal and passes 

 downward and forward, enveloping the base of the pectoral fin; the 

 second passes over the tail at the base of the soft dorsal, being nearly 

 as broad as the fin is long, and extends downward to the anal; its 

 lower anterior part is cut by a more or less definite large white spot ; 

 the third band covers the greater part of the caudal peduncle; its 

 posterior edge has a deeply shaded concavity, which appears to be 

 peculiar to the species. Tlie color pattern here described is vaguely 

 outlined in the type and cotypes. The young specimens have a 

 smooth head, wliile only a trace of the strong occipital ridges and the 

 elevated bony crest of the suborbital stay appear. The third pre- 

 opercular spine is present in all.
