AMPHIPODA OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 465 
These agree well with the descriptions and figures given by STEBBING, except that 
the larger ones contain rather more joints in the flagella of the two antenne. In the 
second antenna of the male the flagellum is long, about two-thirds the length of the 
animal, and the last joint of the peduncle is longer than the preceding joint, which is 
rather short. In the second maxilla the inner lobe is specially broad and has the inner 
margin pretty strongly convex. The second gnathopod has the palm a little projecting 
so as to approach towards the chelate character. ‘The uropods agree well with the 
description ; the character of the peduncle of third uropod seems fairly characteristic, 
and is shown in fig. 5. Its outer margin is produced upwards into a vertical flange 
above the general body of the jomt; it curves upwards at the end into a subacute 
point, and bears three short spinules on the distal half of the upper margin. The two 
branches are similar in shape, both tapering to the extremity; the outer is slightly 
longer than the inner, and bears a few long hairs at a little distance from the end. 
The species was originally described from specimens in the Copenhagen Museum, 
coming from the Gulf of Mexico. 
Genus ALICELLA Chevreux, 1899. 
Alicella scotiz, sp. nov. (Pl. L figs. 6 and 7.) 
Station 468, South Atlantic, lat. 39° 48’ S, long. 2° 33’ E.; 2645 fathoms. 
29th April 1904. One specimen, 20 mm. long. 
Integument soft, the body greatly swollen about the middle, tapering considerably 
posteriorly. ‘he hinder half of the body somewhat compressed, with a slight dorsal 
ridge, but hardly carinate. Side plates 1—4 increasing in depth, the fourth with its 
posterior lobe extending about one-third along the fifth, which is shallower than the 
fourth and broader than deep. Lateral plate of the first pleon segment angular in 
front but rounded behind, its lower border fringed with long sete; that of the second 
sepment with both angles rounded; the third with the anterior rounded, posterior 
angle quadrate, both bearing plumose setze on the lower margin. Sides of the third 
segment of the urus upraised alongside the telson. yes indistinct, apparently forming 
a narrow crescentic band along the lateral sides of the head. 
Antenne slender, first shorter than the second, about as long as the head and the 
first seement of the perzeon, the first joint short and thick, as long as the second and 
third together, the third very short; flagellum of about twenty joints, the first as long 
as the next five and supplied on the inner side with dense tufts of long sete, similar 
setze being present also on a few of the succeeding joints. Accessory flagellum nearly 
half as long as primary ; of six joints the first as long as the next two. 
Second antenna with third joint well exposed; the fourth with long, rather stout 
setules on the lower margin; fifth slightly longer than the fourth, with long slender 
setze on lower margin; flagellum many-jointed, of about thirty-five joints, all except 
the more distal ones bearing a small tuft of long sete at the lower distal angle.
