MR. H. R. HOGG ON 



It is hollowed for each coxa, between which and itself is a 

 marginal space. The base of the lip joins it on the upper edge 

 but not the maxillae. The rough upstanding hair thereon is 

 thicker near the edge than in the centre. 



The abdomen is longer than broad, truncate in front, broadest 

 about the middle and pointed at the rear end, where the 

 spinnerets are terminal. It is moderately thickly covered with 

 shoi-t upstanding and finer downlying hair. Tlie ventral tracheal 

 fold is rather close behind the spinnerets. 



The inferior spinnerets are one-jointed and conical, close 

 together and rising from a membranous base ; the superior are 

 longer, flatter and broader, with a short pointed second joint. 

 There is a large well-formed colulus in front of the inferior pair. 



The legs are moderately stout, the tarsi and metatarsi cylin- 

 drical. On the two latter joints of all legs is a scopula with claw- 

 tufts of flat pointed bi^istles. The two claws have about five pectin- 

 ations. There are numerous long spines on the upper side of the 

 femora and on the tibial and metatarsal joints. 



The palpi are rather short and fine, the femoi'al joints incurved, 

 and spines on the tibial and distal joints. The tibia is longer 

 than the patella. 



The measurements (in millimetres) are as follows : —

This would appear to belong to M. Simon's genus Fhilisca 

 from Tierra del Faego etc. It difi'ers from P. navarinensis TulL, 

 to which it approximates, in having the side eyes quite 1| dia- 

 meters apart instead of 1 diameter ; in having the i-ear median 

 twice as far from one another as from the side eyes instead of 

 equidistant, and the row procurved instead of straight ; the front 

 median decidedly less than three-fourths of the laterals ; the 

 second pair of legs as long as the first, instead of shorter ; at the 

 rear end of the dark median line on the back three black arrow-- 

 headed cross markings instead of testaceous spots ; and the fourth 

 pair of legs longer in proportion to the others ; the epigyne is also 

 apparently different.
