C. Koch in Die Arachn., loc. cit. , mentions "gebogenen" spines 

 on the legs of Dufour's Dol. spini manus ') , and accordingly does not 

 accept the identity of that species, or D. Dufourii Walce. 3 837 2 ), 

 with his Zora ocreata Or D. Dufourii Walce. 1841. This however 

 arises from a misunderstanding, for neither Dufotjr nor Walckenaer 

 says that the spines are curved, but oppressed ("tout a fait couches"), 

 when the animal does not spontaneously erect them. Nevertheless 

 it appears to me very uncertain whether D. spinimanus Dof. (Z). 

 Dufourii Walce. 1837) be the same species as Z ocreata C. Koch, 

 for in D. spinimanus the 1 :st pair of legs is said to be the longest, 

 then the 2:nd pair, and "afterwards the hind legs". The colour of 

 the abdomen appears also to differ : it is in fact described as "blond, 

 picotte de noir et marque de deux taches dorsales , I'une vers son 

 tiers anterieur, V autre a, son extrSmite". There would therefore seem 

 to be reason to retain, for the present at least, the specific name 

 ocreata C Koch for the spider which Walceenaer in Vol. II of his 

 H. N. d. Ins. Apt. has described under the -name of D. Dufourii. 



In Z. ocreata, both cT and ?, the 1 :st and 4:th pairs of legs 

 are so nearly equal in length , that I dare not decide which is the 

 longer. In a J (from Algeria), whose cephalothorax is near 6 mil- 

 lim. long, these pairs are about 19 millim., the 2:nd pair 17 and 

 the 3:rd pair 13'/ 2 ; in a cf , whose cephalothorax hardly exceeds 4 

 millim., the l:st and 4:th pairs are 18'/ 2 millim. long.
