which I have had the opportunity of examining (a c? and ? from 

 Paris, with which I have heen obligingly favoured by Simon), 

 no white spots are visible on the abdomen, nor are any such spots 

 mentioned as distinguishing this species either by Walckenaek, 

 C. Koch or Simon, whereas C. Koch has described what he con- 

 siders as a separate species, Pyroph. tijroliensis (loc. cit. , p. 29, 

 figg. 1097, 1098), in which the abdomen in front of the black half 

 of the back has two white spots. But also in "Pyrod. formicarius" 

 the colour of the abdomen appears to be variable: Simon says that 

 in the female it "presente souvent une ou deux taches fauves trans- 

 verses au dessus des filieres"; Blackwall's figure of his Salt, formi- 

 carius exhibits a white band broken in the middle just in front of 

 the dark posterior portion of the abdomen ; and I have received from 

 Mr L. v. Kempelen two specimens, preserved in spirits, of a Salticus 

 from Austria, which agree far better with De Geer's description and 

 figure than my French specimens of Pyrod. formicarius , without 

 however appearing to me specifically different from these. 



In these Austrian specimens (probably imperfectly developed 

 females) the abdomen is of a pale reddish grey colour, and has be- 

 hind the middle a broad, dark, transverse band almost geminated 

 by a pale transverse line or patch; lower down, on the sides of the 

 abdomen, this dark band is dilated in front, and there sends out a 

 dark tooth upwards and inwards: between the band itself and these tooth- 

 like portions, the abdomen seems to have been covered with white hair, 

 which probably formed a patch on both sides (as in "P. tyroliensis" , 

 according to C. Koch). Behind the broad transverse band, the abdomen 

 is of the same pale colour as in front of it, with two dark patches 

 or angular lines , one immediately behind the band and one just above 

 the anus. In the large pale field before the transverse band, a dark 

 patch appears on each side (an angular band interrupted in the middle). 

 The legs are yellowish, with black lines and the metatarsi of the 

 first pair black. In one of the specimens the thighs of the 1 st pair 

 have a dark line on the upper side, and a short similar line on the 

 inside, at the base; the thighs of the succeeding pairs have a black 

 line on the fore side; the thighs and patellae of the 4 th pair are at 

 their apices blackish; the tibiae and metatarsi of the 4 411 pair have 

 a dark line on the outer side, and (the metarsi at least) a similar 

 line on the inner. In the other specimen the dark lines on the legs 

 are partly effaced and not so distinct. Both specimens appear to 

 me very similar to the spider described by C. Koch as a c? jun.
