Scams paluca Jenkins, new species. Native name, Palnkaluka. Fig. 18. 
Head in body to base of caudal 3, in total to tips of middle caudal rays 3.68. Depth in body to 
base of caudal 2.8; in total to tips of middle caudal rays, 3.5. D. ix, 10. A. II, 9. P. 14. Scales 
24; lateral line interrupted ; tubes mostly many-branclied, a few single. At interruption two scales 
with tubes stand immediately above first two of series following interruption; scales very slightly 
roughened by radiating lines of granulations extending to margins of scales. Body moderately deep. 
teeth at posterior angle of upper jaw, one at angle of lower jaw. Cheek with two rows of scales, 
seven in upper row and 4 to 5 in lower, the margin of one or two scales of lower projecting over anterior 
limb of preopercle; a series of scales along margin of opcrcle; a series of 4 scales along median line 
before first dorsal siiine. Dorsal spines flexible; caudal .fin middle margin straight, the lobes pro- 
duced nearly the length of middle portion of fin in longest specimen, less so in smaller ones. Caudal 
peduucle 2 in head. Pectoral 1.3 in head, its breadth about two-thirds its own length; ventral 1,6 
in head, not reaching vent by one-half to one-fourth its length, inserted but slightly back of a vertical 
from anterior insertion of pectoral. 
Color notes from freshly collected specimens not obtained. Specimens in alcohol (evidently much 
faded) are pale, with upper parts of body somewhat dusky ; upper lip greenish-blue, margin of same 
color. This color from each lip unites behind angle of mouth into a band which extends to anterior 
margin of eye and passes along lower margin of eye, ending in a small, indistinct (in alcohol) area 
behind eye; transverse bar of same color across the chin. Back of this, on the throat, are markings 
of bluish-green; outer margins of dorsal and ventral and upper and lower margins of caudal fins 
bordered by same color, also anterior margins of pectoral and ventral lius; indistinct markings of 
same color appear on caudal. 
Fig. 17. — Scarus gilberti Jenkins, now species. Type, 
This species resembles Scants octodon Bleeker. Five specimens were obtained by me in 1889, and 
one by the Albatross in 1896. Type 6140, L. S. Jr. University Museum. The measurements of three 
are given below :
