Plate XII. 



Aganippe rainbowi, n. sp. 



9 • Described from living specimen. Cephalo-thorax, 

 5 mm. long, 4'5 mm. broad. 



Cephalo-thorax : — Obovate, nearly as broad as long, 

 black or very dark brown, shining, entirely devoid of hairs 

 except two or three stiff ones between the eyes. 



Pars cephalica: — Elevated, arched, distinct segmental 

 groove. 



Ocular area: — Twice as broad as long, raised, arched, 

 and provided with bristles. 



Clypeuz:— Narrow, sinuate, sloping forward, weakly 

 indented at middle. 



Pars thoracica: — Broad, fully curved at sides, sloping 

 backwards, well-marked radial grooves. 



Fovea: — Deep, short, procurved. 



Marginal band: — Hardly sinuate, bare of hairs. 



Eyes: — Front row very slightly recurved, the laterals 

 equal in size or slightly larger than medians, are elevated 

 on black bases, looking forwards and outwards. The medians, 

 separated by rather more than their diameter from the 

 laterals, are not elevated, and are separated from each other 

 by one-half the diameter of a median eye. Posterior row 

 procurved. The laterals are the larger, nearly equal in size 

 to the antero laterals. They also are raised on elevated 

 bases, looking backwards and outwards. The medians are 

 small and not elevated, their inner border is convex, and 

 their flat outer border is in contact with the base of the 

 corresponding postero lateral. The distance between the 

 postero medians is exactly that of the extreme outward limit 

 of the antero medians. 



Legs: — Similar in colour to thorax; relative lengths, 

 4, 1, 2, 3; the two anterior pairs armed with long black 

 spines, 5 metatarsi, and tarsi of 1 and 2 scopulate. Tarsal 

 claws well developed. Two posterior pairs less robust, clothed 

 with long stiff hairs and an occasional spine. 



Palpi: — Concolourous with legs, robust, clothed- with stiff 

 hairs and bristles, tarsal joint scopulate.
