margin of falx-sheath instead of three; three on superior 

 margin. About five pectinations on superior tarsal claws 

 instead of about nine. 



The trochanters of all four pairs of legs are slightly but 

 clearly hollowed on the underside. This, with the mandibular 

 fringe and shape of lip and maxillae, breaks down the last 

 quotable distinction between the Agalenidae, Pisauridae, and 

 Lycosidae. 



Pacijicana Cockayni, sp. n. 



The colour of the cephalothorax is dark brown, the cephalic 

 part being bounded by a pale yellow marginal stripe. A 

 similar pale yellow area extends round the thoracic part 

 almost to the margin, where there is again a narrow streak 

 of brown. The mandibles are dark brown. Lip and maxilla? 

 paler brown, yellow on the outer edges of the latter. Sternum 

 pale brown on each side, with a longitudinal central yellow 

 streak. The legs and palpi are yellow, with brown rings, 

 one near the anterior end of the femur, one on the patella, two 

 on the tibia, two on the metatarsus, one at the anterior end of 

 the tarsus. In the front pair the whole of the tarsus and 

 metatarsus is brown. The abdomen on the upperside has a 

 series of transverse scolloped stripes yellow and black alter- 

 nately. The underside is greyish yellow. 



The shape of the cephalothorax is a long oval, truncate at 

 the slightly narrowed anterior end. The cephalic part is 

 considerably raised above the thoracic; a short, shall 3 w, 

 longitudinal fovea extends from behind the cephalic part to, 

 but not down, the rear slope. 



The pattern of the eyes is quite unique. The front laterals 

 are large, one and a half diameters apart, and one third of 

 their diameter from the margin of the clypeus. Four small 

 intermediate eyes one fourth of the diameter of the above are 

 situated between them at the coiners of a trapezium, the rear 

 pair, their diameter apart, slightly above the line joining the 

 upper edges of the laterals; the lower pair, rather farther 

 apart, are below the line touching the lower part of the laterals. 

 The lateral eyes of the rear row, rather more than their 

 diameter apart, are about three fifths the diameter of the front 

 laterals and the diameter of the latter away from their own 

 median. The small front median eyes are their diameter from 

 the margin of the clypeus. 



The mandibles are nearly twice as long as the front 

 patellae, much kneed at the base, and taper to the anterior 

 end, the fangs being rather long, slightly curved, smooth for 

 the first half and striated longitudinally the second. The
