FIJI-NEW ZEALAND EXPEDITION tf! 
and plate-like, biramous, the exopodite being the broader and 
edged with hairs. They appear to be much more powerful swim- 
ming organs than those of Squilla, the common member of the 
family on our coasts. The last abdominal segment has a very 
heavy tergum which is strongly corrugated longitudinally; the 
telson has three similar corrugations proximally and ends in two 
strong points, one on either side of the median line, with two 
shorter lateral points on either side of these. The inner borders 
of the two central points are very finely serrate. The last swim- 
meret extends backward beyond the telson. 
Gonodactylus, much more heavily built and less delicate than 
Squilla, is an inhabitant of the shallow pools on the surface of the 
flats, and is one of the most common and conspicuous of the ecrus- 
taceans that we found at Makuluva. . 
A large erayfish, or spiny lobster, lives in the rocks and shal- 
lows around the reefs, but we did not succeed in securing spec- 
imens. I suppose it belongs to the genus Palinurus which is 
common in the West Indies and a much prized dainty when 
properly cooked and served. Crayfish are caught at night by the 
Fijians who use torches whose bobbing lights could be seen around 
the island on calm nights at low tide. 
One of the notable things about the crustacean fauna of Maku- 
luva is the scarcity of Cirripedia or barnacles. I find no reference 
to them in my notes nor do I recollect seeing them. These almost 
universally distributed forms are familiar on all American coasts 
both East and West, as well as in the West Indian region. We 
found them later, rather abundantly, on the New Zealand coast. 
A very remarkable slender-legged macruran, found in one of 
the crannies of a coral rock mass, was preserved, but I have been 
unable to locate it since our return. It was pure white in general 
color but with blood-red transverse markings on the carapace and 
appendages. There were blue blotches on the red bars or annula- 
tions and the exceedingly attenuated walking legs had numerous 
thorny processes. 
Owing to the searcity of hydroids and bryozoans on the Maku- 
luva flats, the crustaceans are cleaner than those usually found in 
such places, not being overgrown with symbiotic organisms. 
MOLLUSCA 
Here again we find few really unfamiliar forms, a great ma- 
jority appearing to be generically identical with those found in
