Powell. — On the Spiders of New Zealand. 281 



The spiders seem to be fairly represented in this country. My collecting 

 has been performed in a very desultory manner on occasional holidays, and 

 has been confined almost entirely to the neighbourhood of Christchurch. I 

 have now in my possession specimens belonging to over sixty species of more 

 than twenty genera. The number of genera is very large in proportion to the 

 number of species, and affords an indication of the very wide field which lies 

 open to the collector. 



Genus Salticus, Latreille. 

 PL XIX. 



Eyes disposed in three rows, constituting three sides of a square, in front 

 and on the sides of the cephalo-thorax ', the two intermediate eyes of the 

 anterior row are the largest, and the intermediate eye of each lateral row is 

 much the smallest of the eight ; maxillae short, straight, enlarged at the base, 

 where the palpi are inserted, and at the extremity w^hich is rounded ; lip oval, 

 obtuse at the apex ; legs robust, varying considerably in their relative length 

 in different species. 



Of the genus Salticus, a very numerous genus in all parts of the world, I 

 have eight species, which are, I believe, undescribed. Of seven of these I 

 append minute descriptions, the eighth is a solitary immature specimen which 

 I shall not at present describe. 



1. Salticus appressus, n.s. Fig. 1. 



Length "8 inch. 



Cephalo-thorax oblong ] body remarkably flattened or depressed, nearly 

 quadrilateral, about twice as long as broad ; caput scarcely defined from the 

 thorax, exceedingly flat ; eyes of middle row rather nearer anterior laterals 

 than posterior row ; thorax about two and a half times as long as caput. 



Colour in some specimens uniform grey, produced by a coat of close short 

 grey hair on a black ground. In adult males longitudinal black stripes on the 

 grey ground, varying much in distinctness. 



Legs, order of length, 4, 1, 2, 3 ; fourth pair rather long and slender. 

 First pair very broad, flattened out, especially the femoral joint j second pair 

 robust and flattened, but far less so than first pair ; third pair far the smallest 

 and slenderest. Colour brownish grey, clothed with short grey hair. 



Palpi not very large or long ; palpal organ tumid, with a slightly curved 

 short filament at extremity ; a strongish slightly crooked spine on outer aspect 

 of radial joint ; radial and digital joints clothed with long greyish hairs. 



Falces most remarkably small, corresponding in width to anterior middle 

 pair of eyes, and no deeper than they are broad, inclined forwards. 



Maxillse small, slightly inclined towards lip, dilated at extremity. Lip 

 oval, rather longer than broad.
