264 MEMOIRS OP THE CARNEGIE MUSEUM. 



Body colorless, probably light red or yellowish in life, save on membranes of 

 spinous dorsal, on which is a row of spots of black; smaller spots are present at 

 the same level on the spines; peritoneum colorless. 



199. Iniistius dea (Temminck & Schlegel). (Plate XXXI, fig. 7). 



Sagami Bay, No. 6008a; Misaki, No. 6296a-d; Yokohama, No. 6287a, 6377a-b. 



A young specimen from Sagami Bay, but eighty-four millimeters in total 

 length, shows the juvenile coloration well, and a figure is given on Plate XXXI. 

 In the adults the bands are very faint and the coloration of the fins has entirely 

 changed. At a length of one hundred and thirty millimeters the bands are slightly 

 stronger in coloration. The closely allied species, Iniistius pavoninus of the Hawaiian 

 Islands, shows an exactly similar change, the bands, however, being distinct in 

 specimens reaching as much as one hundred and fifty-five miUimeters in length. 

 The pre-orbital depth is very much less in the young than in the adult. These 

 changes we have followed in detail in Iniistius pavoninus and partially in Iniistius 

 dea. The species are so closely allied that there is no question that the same laws 

 of change in color apply. A careful comparison of a large series of specimens and 

 measurements taken in hundredths of body-length showed no prominent differences 

 between Iniistius dea, I. pavoninus, and /. niger, the principal differences being 

 those of color.
