538 IVAR TRAGARDH 
Pseudostigmata circular, pointing straight upwards, with the inner part 
of the trumpet directed straight forwards and with numerous radiating septa. 
Pseudostigmatic organs with very short, thin peduncle and large, pyri- 
form head. 
The posterolateral angles of the propodosoma are thickened and project 
backwards as broad, conical teeth. Between them, exactly behind the lamelle 
there is a second pair of larger, more elongated and obtuse teeth. 
The hysterosoma has at the anterior margin a pair of large triangular 
teeth opposite to the lateral teeth of the propodosoma and between them the 
anterior edge seems to be thickened to 
a narrow ridge, behind which there are 
two rather indistinct, low projections. The 
hysterosoma is extremely finely punc- 
tured, but along the sides there is a 
band where it is finally transversally 
striated. There are two longitudinal rows 
of 7 hairs near the median line, about 
twice as long as the interlamellar hairs, 
and 3 pairs of submarginal hairs in the 
posterior half. 
On the level of the anterior median 
hair there is on the marginal band one 
oblique, narrow, slit-like pore and an- 
other in front of the anterior submarg- 
inal hair.

and anal shields of typical shape. Legs

Loc.: Juan Fernandez, Masatierra, Puerto Ingles about 4oo m. a. S., 
among dry leaves in dense forest. Aug. 1917. One specimen. 
11. Odontocepheus curtipilus n. sp. — Figs. 63—65. 
Amongst the dry leaves already mentioned numerous specimens of a 
fourth species occurred which is closely related to but quite distinct from O. 
longipilus. 
Length 880-900 ».; width 340—370 wu; length of propodosoma 320— 
330 wu, width 200 uw. 
Colour light brown. 
Texture very finely punctured except at the sides of the propodosoma 
where these in the same scaly texture as in Osocepheus pacificus and O. longipilus. 
Propodosoma (fig. 63) of the same general shape as in O. longipilus 
and O. sexdentatus, but the lamella are narrower, the lamellar and rostral hairs
