Calotomus irradians Jenkins, new species. Fig. 15. 
Head 3.33 (in total 3.9) ; depth 2.33 (2.9). D. ix, 10. A. hi, 9. Scales 25. Teetli pointed, both tips 
and margins free, posterior surface adnate to dental plate, of about equal size in both jaws; at least 
one strong tooth at posterior angle of each upper jaw, curved backward and downward; teeth in 
oblique series of about 5 series in each half of upper, and of about 8 series in each half of lower jaw ; 
3 to 4 teeth in each series. Scales on cheek in a single series, 6 in number, 4 scales in median line 
before dorsal, 3 scales before ventral, this line continued by 2 scales between bases of ventrals, form- 
ing a sort of appendage in this position; scales not reduced on breast; one and one-half series of 
scales between lateral line and base of dorsal, the half series only slightly sheathing base of dorsal 
fin. Dorsal spines flexible; origin of dorsal, base of pectoral, and base of ventral fins in a vertical 
line; posterior margin of caudal a straight lino, except moderate prolongation of upper rays, longest 
ray 2.4 in head; ventrals reaching halfway to vent; pectoral fin broad as long, longest rays (second 
and third) 1.5 in head. Posterior margin of fin slightly convex. 
Color in life: General color of body and fins blue; head, chin, and throat bright-blue, marked 
with pink, arranged as follows: About 8 bands radiating from eye and a number of hands and irregu- 
lar figures on snout, face, and occiput, and a few small spots on chin ; of the pink bands radiating 
from eye 2 reach region of angle of mouth, 2 join the irregular markings on face and occiput, and 4 
radiate over the region of cheek and behind eye ; a vertical bar of pink on each scale ; in some regions 
this bar is partly concealed by overlapping scale; vertical fins bright-blue, with reticulations and 
spots of pink; ventrals blue; pectorals blue, olive, and pink. 
This very beautiful fish is somewhat rare and is very highly prized by native fishermen for 
virtues they suppose it to possess. They usually ask an exorbitant price for it. The description is 
based on two specimens, one obtained by me in 1889 and one by the Albatross in 1896. Type No. 12142, 
L. S. Jr. University Museum. The measurements of the two are given below:
