AMPHIPODA. 
R. Buciiiiolz makes some general observations on the structure of this 
order, chiefly on the peculiar appendages of the antennae in the males ; 
he points out that these are generally formed of three cup-like pieces, 
placed somewhat obliquely above each other, and suggests that they may 
serve as prehensile or clasping organs. Zweite deutsche Nordpolarfahrt, 
ii. pp. 294-298. 
S. I. Smith has found that a large portion of the third and fourth 
pairs of thoracic legs is filled with a peculiar opaque glandular sub- 
stance in some tube-building Amphipoda, and occupied by muscles in 
those species which do not build tubes ; the greater part of this gland is 
situated in tlio basal joint in the genera Xcmolea, Amphithoe^ and 
Ccrapus, and in the basal and meral joints in rUlochiriis^ Ampdisca^ 
and Byhlis. The terminal joint of these legs is truncated at the tip 
and tubular ; and there can be no doubt that these are the glands 
which secrete the cement with which the tubes are built. Am. J. Sci.
