AMPHIPODA OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 509 
Hyale saldanha, sp. nov. (PI. II. figs. 24-29.) 
South Africa, entrance to Saldanha Bay, Station 483; 25 fathoms. 21st May 
1905. Several specimens, males and females, the largest about 9 mm. long. 
Specific Description.—Male.—-Back rounded, not carinate, and without dorsal teeth. 
Pleon segment three, with postero-lateral corner quadrate with slightly produced point. 
Hyes of moderate size, round. ‘The first antenna (fig. 24) reaches to the middle of the 
flagellum of the second ; peduncle with first joint much longer and broader than the 
second, and produced below at its distal end into a rather broad expansion, which appears 
to have a vertical flange, and at the lower part of this a thicker conical portion tipped 
with two setz ; second joint with a smaller similar expansion ; flagellum of sixteen joints 
all bearing a fairly distinct tuft of long setze at the lower distal angle. Second antenna 
(fig. 24) about one-third the length of the body; last two joints of the peduncle sub- 
equal; flagellum of about thirty-five joints. First gnathopod (fig. 27) with the basos 
rather broad except at the base; the carpus short, triangular, its posterior margin pro- 
duced into a rounded fringed lobe ; propod oblong, widening slightly distally, front margin 
convex and smooth, hind margin straight or very slightly concave, with a group of 
spinules at the centre; palm oblique, slightly convex, shorter than hind margin, defined 
by two stout spinules, the finger fitting closely up against the palm. 
Second gnathopod (fig. 28) with basos expanded distally into a flange on the outer 
margin, ending in a rounded lobe at the extremity ; ischium with a similar rounded pro- 
cess; merus short, its apex subacute ; carpus very short, fitting closely into the emargin- 
ation on the base of propod; propod large, oval, slightly narrowing distally, its anterior 
border regularly convex and smooth; palm oblique, longer than the hind margin, 
straight except for a rounded process near the base of the finger, fringed with a double 
row of short spinules and defined by two stout spines ; finger stout, fitting into a small 
pocket at the end of the palm. Perzeopoda one to five robust; propod slightly curved, 
especially in the last three pairs, its concave margin bearing at regular intervals three 
stout spinules of about equal size, all minutely serrated towards the end, but without 
a specially large serrated spine; posterior border of propod unarmed; finger strong, 
about half the length of the propod, much curved, inner setule very small; in the third 
perzeopod (fig. 29) the basos is rounded, projecting inferiorly as far as the end of the 
ischium, in the fourth and fifth similar, but in the fourth the basos is slightly narrower 
than in the third and fifth ; hind margins of basos in all either smooth or only faintly 
erenulate. Uropoda short, the first with peduncle about as long as the branches, and with 
two or three spinules along its lateral margins and a stout curved spine at the distal end ; 
branches subequal, with lateral and terminal spinules. Second uropod similar, but with 
peduncle shorter than the branches. Third uropods with the branch rather shorter than 
the base, both with stout terminal spinules. ‘Telson with a stout spinule on each half. 
Female.—Similar to the male, except in the gnathopoda, which are shown in 
figs. 25 and 26.
