594 IVAR TRAGARDH 
hairs; anal aperture wider and more rounded, situated close to the posterior 
margin and as far from the genital aperture as its own length. 
Legs. Legs I and II (fig. 79) with clavate femora with thin ventral edge 
and two stout dorsal bristles in the distal Is; genu short, curved, with stout 
dorsal bristle, one dorsal perpendicular tactile hair, one ventral bristle and one 
hair exteriorly. Tibia clavate, widening from a very slender base towards the 
top where it is widest and coalesced, apparently without any movable joint, 
with the tarsus which is almost pyriform in outline and has numerous but 
short hairs; claws stout. 
Legs II (fig. 78) and IV with flattened femora, with ventral narrow thin 
blade; tibia and tarsus of the same shape as in legs I and II but longer.

14. Cepheus corpulentus n. sp. — Fig. 83—86. 
Length 710 », width 500 %; length of proterosoma 230 uw. 
Colour dirty greyish brown. 
Mesziure: 
Propodosoma (fig. 84) of the same general shape as in C. crénztus, as 
are also the lamellae, which are, however, united by a narrow translamella. 
The interlamellar hairs are short but stout and slightly serrated as the hairs 
of the hysterosoma. Lamellar hairs short, pointed, curved inwards and inserted 
on the dorsal edge of the lamella at the base of the cusps which are of the 
same shape as in C. crinitus. Rostral hairs of the same size as the lamellar 
hairs, inserted in front of the translamella. Rostrum blunt, with a median 
rounded depressed area. 
The semispherical projections are larger than in C. crinitus and in the 
posterior part there are about 12 circular depressed areas. 
Pseudostigmata large, tube-shaped, fused with the base of the lamellz. 
Pseudostigmatic organs slightly s-curved, with lanceolate heads, covered with 
fine raised points. 
Mouthparts. Hypostome (fig. 83) of the same general shape as in C. 
crinztus but comparatively shorter and broader. 
Hysterosoma (fig. 85) with well developed shoulder, sloping gently 
downwards towards the posterior margin, where there are about 30 circular 
areze porosz. There are two longitudinal rows of short but stout and slightly 
serrated blunt bristles, one median row of 5 pairs and one lateral row of 4 
pairs; besides there is one shoulder bristle, three pairs at the posterior margin 
and one pair further ventrally near the median line.
