566 DR THOMAS SCOTT ON THE 
Habitat.—Scotia Bay, South Orkneys; collected in June 1903; Station 325, 
60° 48’ 42” §., 44° 38’ 33” W. 
Remarks.—The present form has at first sight a superficial resemblance to Lao- 
phonte minuta, Boeck, but a closer examination reveals certain differences in the 
structure and armature of the first and fifth pairs of thoracic legs, as well as one or two 
other anatomical details sufficient to exclude it from that species. 
Laophonte wiltont, new species. (Pl. VII. figs. 7-15.) 
Female.—Body slender and elongated and somewhat similar to the species described 
above in its general appearance. Length of the specimen represented by the drawing 
is about 0°9 mm. } 
The antennules are composed of seven joints, and the first three are tolerably large 
and subequal; the fourth and fifth are very short, while the next two, which are nearly 
of equal size, are each about one and a half times as long as the fifth. Antenne and 
mouth organs nearly as in the species previously described. 
The first pair of thoracic legs are tolerably slender, the outer ramus, which reaches 
to the middle of the first joint of the inner ramus, is three-jointed, and the middle joint 
is rather longer than the first or third. The next three pairs are somewhat similar to 
those in Laophonte australis. 
In the fifth pair, the basal jomt is somewhat narrow and subtriangular in outline, 
and reaches to beyond the middle of the second joint; it is provided with six sete, 
three of which spring from the inner margin and two from the outer margin, and one 
is articulated close to the apex. The second joint is moderately expanded, the greatest 
width more than half the length ; distal end produced, triangular in form and provided 
with one seta on the inner margin, one at the apex, and five on the outer margin. 
Caudal rami as long as the last segment of the abdomen. 
Habitat.—Scotia Bay, South Orkneys, in some siftings from dredged material 
collected in June 1903 ; Station 325, 60° 43’ 42” 8., 44° 38’ 33” W. 
Remarks, —This species is rather smaller than any of the other Laophontes described 
here, and it may be distinguished from them not only by its size but also by the 
structure of the first pair of thoracic legs, and by other, though perhaps less obvious, 
differences. The species is named in compliment to Mr D. W. Witton, one of the 
naturalists who took part in the Scottish National Antarctic Expedition. 
Genus Laophontodes, T. Scott, 1894. 
Laophontodes whitsoni, new species. (PI. VILL. figs. 1-8.) 
Female.—Body narrow, elongated, and tapering slightly towards the distal extremity ; 
the animal has a general resemblance to the female of Laophontodes typicus, T. Scott, 
but is rather more slender, and the caudal rami are short, whereas in the species men-—
