the corresponding part of the anal, and the third connecting the 

 posterior part of these fins. These bands are as wide as, or slightly 

 wider than the interspaces, embracing from three to five scales. 

 There is also a dark band at the base of the caudal rays ; this is 

 connected with the last body band by a less indistinct median 

 streak. Each scale has a broad, slightly darker margin, immedi- 

 ately within which is a vertical line of light blue. This line is 

 much broader on the scales, covered by and above the pectoral, 

 and on the ground colour posterior to this fin is a large sulphur- 

 yellow blotch. Beneath the sixth and seventh dorsal spines, on 

 the row above the lateral line, two scales have the margin quite 

 black, and the light blue lines within are very broad ; they thus 

 form a conspicuous feature. The first dorsal, or occipital fin is of 

 bluish grey colour, its membrane diagonally crossed by dark green 

 lines, and its filamentous portion black. The dorsal proper is 

 greenish, with darker margin, and a blue submarginal band ; 

 below this is another darker broken band, which gives off irregular 

 diagonal lines to the base of the fin. The anal is reddish at the 

 base, greenish towards its free edge ; it has a dark margin and 

 blue intramarginal band, within which are a number of blue 

 spots. The first ray of the pectoral is light, followed by a dusky 

 streak, which suffuses the posterior margin of the fin, leaving the 

 lower base pale. The ventral is bluish-grey, has a dusky margin, 

 and the produced portion of the first ray black. The caudal is 

 greenish, and the markings are similar to those of the anal, a 

 broad dark margin and some blue spots within ; the upper and 

 lower rays are also blue. 



Total length 320 mm. • 



The intestines contained small shells, including a Trochus, 

 pieces of coral rock, and bladders of a seaweed (Sargassxim). 



A consideration of all the characters leads me to regard this 

 specimen as allied to, but distinct from, the fish obtained on the 

 coast of California, and described by Gill as Iniistius mundi- 

 corjyusP Not having the original description, my comparison is 

 made with the account published by Jordan and Evermann,'^ 

 from which it will be seen that some differences occur in the 

 relative proportions, particularly of the pectoral fin. The American 

 examples taken at Cape San Lucas (at the entrance to the Gulf 

 of California) and the adjoining coast of Mexico, do not exceed 

 eight inches in length, whereas ours measures nearly thirteen 

 inches. 



In deciding to regard this fish as distinct from /. viundicoiyus, 

 I have also been influenced by a consideration of geographical 

 conditions. Unlike the surface or deep-sea fishes, which have
