FIJI-NEW ZEALAND EXPEDITION 61 
these natural aquaria, or the festoons and fronds of vivid green, 
pink and purple sea-weed of various sorts that add to the charm. 
But there is more than this; one would have to_hear the booming 
roar of the nearby surf, feel the rush of fresh sea air and ex- 
perience the tang of excitement furnished by the occasional high 
breaker that sweeps suddenly and most unexpectedly over the 
slippery rocks on which one stands, before the picture could be 
completed. 
As to the fishes in these larger pools, the most conspicuous and 
numerous are colored the deepest most vivid blue imaginable, the 
deep blue of stained glass. They were so wary that we failed to 
secure specimens and so could not identify them, but they ap- 
peared to be blue parrot fishes. An ‘‘angel fish,’’ grayish with 
sharp longitudinal markings, yellow tail, eyes and gills a brilliant 
blue, was rather common. Then there were gaily decorated butter- 
fly fishes (Chetodon) mainly yellow but with sharply contrasting 
bands and dots of black. Balistide of several kinds add their gay 
reds, yellows, greens, black and white to the general color scheme. 
Many visitors come from Suva to Makuluva to enjoy these wonder- 
ful tide-pools and their gaily decorated inhabitants, which certain- 
ly furnish a sight well worth seeing. 
Several species of these reef fishes stay between tides in re- 
cesses of the rock entirely out of the water. Alfred found an 
angel fish and a trigger fish in one of the big coral rocks at least 
two feet above the general surface of the flats that were at the 
time well above water level. 
One of the most interesting fishes we secured does not occur on 
Makuluva but is found in the mangrove swamps that line the 
shore of Vitilevu opposite our little island. It is the Pertoph- 
thalmus, or climbing fish, allied to the gobies. This little creature 
has very pronounced goggle eyes, raised considerably above the 
level of the top of the head, which it moves independently as it 
surveys the scenery from a mangrove root well above the water. 
The pelvic fins are far forward just below the pectorals and unit- 
ed at their bases. They are strong and their inner surfaces can 
oppose each other in a firm grip. These fins are probably the 
main agents by which they climb out, hitch themselves along a 
root or branch and then hold on while they contemplate the world 
above water. The pectoral girdle is remarkably strong and solid 
and the pectoral fins ean be bent in an abrupt angle which doubt- 
less helps them in working their way between stones or even grass
