higlily developed, of great size and complicated structure. 

 Any minute description was rendered impracticable, owing to 

 the specimen being gummed upon a piece of card — a circum- 

 stance which also prevented any observation of the maxill^i, 

 labium, and sternum ; the falces also were almost entirely 

 hidden : they appeared, liowever, to incline strongly backwards 

 towards the maxilla. 



Abdomen so much shrunk as to make it difficult to describe 

 it with any accuracy ; apparently it was long, narrow, oval in 

 form, of a blackish colour, clothed with white hairs on the 

 sides, and some greenish-yellow, metallic-lustred, scale-like 

 hairs on the upperside ; two of the spinners were apparently 

 much longer than the rest, and curved strongly upwards. 



A single adult ^ in the Hope Collection, Oxford, received 

 from Ceylon, where it was captured by Mr. G. ILK. Thwaitcs. 

 It is probable that, upon a revision of the Salticides, the genus 

 Lyssomanes, established by Mr. Hentz, in his ' History of 

 American Spiders' {loc. cit. sup.), will sink into a subgenus 

 of the genus Salticus. 



Family Salticides.

Excepting the legs, the wliole of this curious little spider is 

 of a jet-black colour, with a scmicorn(>ous integument, Avhich is 

 shining and marked thickly with minute punctures. Cephalo- 

 thorax, looked at from above, nearly square, and arched on all 

 sides ; normal furrows, defining caput and thoracic segments, 

 quite obsolete ; the profile of the abdomen and cc])halothorax 

 describes almost a semicircle ; the fore margin of the abdomen 

 slightly covers or overlaps the hinder ])art of the ccphalothorax ; 

 and from the structure of these parts it seems probabk' tliat, when 

 alive, the s])ider has the power of raising its ccphalothorax so 

 as to throw it almost com})letely back beneath the semicorneous 

 integument of the abdomen. 



L('(/s short, pale yellowish in colour, apparently not greatly 

 diffl'ring in length, those of third })air shortest. The speci- 

 men, however, ])eiiig dry, it was inqxissible to be certain upon 

 this ])()int. 



I\(/pi so concealed as to be incapable of description, and, in 

 fact, to leave the sex of the spider doubtful. 



Eyes in three rows, occupying the greater area of the ccphalo- 

 thorax ; their position is similar to that of the Saltlci in general,
