middle ; a very distinct white line from the anterior angle of the ce- 

 phalothorax, continuing down the side and carried along each side of 

 the abdomen ; the cephalothorax and abdomen on the inner edge of 

 the white line of a deeper brown colour ; the legs and palpi of a pale

This species, which is described from a male, differs from the Dolo- 

 medes mirificus, Walck. Apt. i. 355, and the Dolomedes sagittiger, 

 as well in markings as in size. 



Dolomedes sagittiger. 



Cephalothorax of a very deep brown ; the extreme edge of the sides,, 

 where the legs are inserted, pale ; a wide yellowish longitudinal line 

 from the anterior angle of cephalothorax; the outside edges with 

 some brown points ; the inner edge with some sinuations ; the band 

 does not reach the end of the cephalothorax ; the middle of the cepha- 

 lothorax with a narrow white line extending from behind the second 

 line of eyes, almost to the end ; on each side of it in front a short 

 interrupted line, somewhat rounded in front. 



Abdomen deep brown, the sides of a palish hue as far as the middle. 



The eyes of the first row very small. 



Legs deep brown, with darker coloured hairs. 



Hab. New Zealand. 



This species seems to be closely related to Dolomedes mirijicus, 

 Walckenaer, Apteres, i. 355. 



Attus Darwin ii. 



Chelicera black, with greenish reflexions, punctured and striated in 

 front, and somewhat impressed at the end ; palpi pale brown. 



Cephalothorax deep blackish brown, highly polished, considerably 

 paler in the middle of the back ; front part projecting very consider- 

 ably over the chelicera ; the front edge behind the first row of eyes 

 with several tufts of short close-set black hairs. 



Eyes with the middle pair of first row very large ; the lateral eyes 

 of first row placed somewhat behind the middle pair, and larger than 

 the two hind eyes ; the eyes on the second line very small, nearer the 

 lateral eyes of first row than those of the third. 



Legs : First pair very long, deep blackish brown ; femoral joint 

 rather longer than the tibial, which is double the length of the genual 

 joint ; the tarsal joint pale at the end ; a small spine near the end of 

 the femoral joint on the inside ; a longer spine about the middle of 

 the genual joint ; three spines placed after each other on the inner 

 edge of tibial joint ; second, third and fourth pairs of legs of a 

 pale yellow, smooth, with a few short bristly hairs on the inside and 

 outside. 



Abdomen small, at the base projecting slightly over the cephalo- 

 thorax with a broad pale line down the middle ; an impressed dark 

 longitudinal line in the middle.
