4 IVAR TRÄGÅRDH, (Schwed. Südpolar-Exp. 
Stigmata situated behind eoxæ IV ; peritremata long, extending closely along 
the outer side of the coxæ and very nearly meeting on the dorsal side above the 
pseudocapitulum. 
The legs. The legs long, the first pair measuring o, 72 mm, the 3rd o, 53 , and 
the 4th o, 5 s mm. 
The cuticle coarsely granulated by short 
irregular, raised ridges arranged transversally. 
Legs I (PI. I, fig. 1); coxa and trochanter 
with fine hairs of ordinary shape; femor, genu, 
tibia and tarsus on the dorsal, exterior and 
interior side with short clavate hairs, generally 
inserted in small tubercles; on the ventral side 
they are provided with two straight bristles 
each, situated in the middle and at the same level, 
one directed obliquely outward, the other inward; 
on the ventral side of the tarsus about 6 sharp bristles and on the dorsal side at 
the end a bundle of fine sense hairs of which 3 — 4 are longer than the others. 
Femur with small, distinctly demarcated basifemur. Telofemur and genu of equal 
length, a litte shorter than the tibia and the narrow, slightly curved tarsus, which 
are also both of equal length; no basitarsus. 
Claws and caruncle very small. 
Legs II (PI. I, fig. 3) thick, with long, narrow, horn-shaped calcar femoralis ; 
no processus axillaris , only a sharp bristle inserted in a small tubercle; processus 
genualis rather long, sharply pointed, directed obliquely forward; on the outer side 
of the femur far back one large, clavate hair, on the ventral side of the tibia in the 
middle one bristle and on the ventral side of the tarsus 4 straight bristles; other 
hairs clavate. Distinct basitarsus. 
Legs III and IV with long tarsi, gradually narrowing towards the end; basi- 
tarsi long, measuring more than z / 3 of the whole length of the tarsi. 
Ambulacres with bilobated caruncle and two subunguinal, narrow slips. 
Epistoma (Text-figure 2) short, triangular, with slightly convex edges, 
projecting in a short narrow, cylindrical spine, bifurcated at the top; the edges with 
4 — 5 sharp teeth. 
Styli present, rather long and narrow. 
Hypostoma (Text-figure 1) three pairs of the hypostomatic hairs situated near 
the front margin; maxillary lobes single-jointed, rather long and narrow and only 
slightly curved. 
The mandibles (PI. I, fig. 6); the lower jaw curved at right angles at the end, 
with large, sharply pointed terminal tooth; the ventral edge of the jaw concave; 
Heterogamasus claviger. Tgdh.
