specimens), which I have received from Dr L. Koch; and I have 

 found that they are alike in every respect. The real T. domestica 

 and T. intricate, certainly much resemble each other, but may ne- 

 vertheless be distinguished without difficulty: the latter is not only 

 larger than T. domestica, but has also comparatively much longer 

 legs. In 1\ domestica ? the 1 st pair is not more than four times 

 the length of the cephalothorax, in T. intricate, judging from a spe- 

 cimen which I met with at Nice (and also according to the state- 

 ment of C. Koch), five times. In both the Greek and English spe- 

 cimens of T. intricate d 1 the first pair of legs is 8 1 /,, times as long 

 as the cephalothorax, in T. domestica d 1 ad. not fully 6 times that 

 length. (In a cf jun. of r T. intricate, that I captured at Florence, 

 the cephalothorax is 8 millim. and the 1 st pair of legs 47 millim. long, 

 accordingly the legs longer than in $, but considerably shorter than 

 in the fullgrown male). The palpi, especially their last joint, are in 

 the cT of 1\ intricate much slenderer than in 1\ domestica cT. In 

 this last, the tibial joint is only double as long as it is broad, the 

 tarsal joint or lamina v bulbi tapering and pear-formed, broader than 

 the mandible (about Vj 2 millim. broad nearer the base and about 3 '/ 2 

 millim. long); the long, compressed appendage, that runs parallel 

 to the lamina, under the bulbus, reaches with its anterior extremity 

 almost to the extremity of the lamina (the distance is less than a milli- 

 metre). In T. intricate or Guyonii, on the contrary, the tibial joint 

 is three times as long as it is broad, the lamina not so broad as the 

 mandible (circa 1 millim. broad and 3 millim. long.): the appendage 

 under the bulbus reaches with its anterior extremity only to about 

 the middle of the lamina. (Compare Blackwall's figure of the male's 

 palpus in his 1\ domestica). 



Walckenaee and others, who believe that At. domestica Linn. 

 is the same as 2eg. domestica Walck., C. Koch, are widely mista- 

 ken. Only a single specimen of this last mentioned species, that 

 namely, which was figured by Clerck, has hitherto been found in the 

 northern or central parts of Sweden: here in Upsala, where Linn^us 

 lived and taught, during my whole residence of 22 years I have never 

 once met with it, whereas T. civilis is here plentiful. T. domestica 

 is not, as Sundevall (loc. cit.) supposed, common over the whole of 

 Sweden, but at most only in the southern and perhaps some of the 

 western provinces ')• 



l) T. domestica (Clerck) has not been found either in Finnland by v. Nord- 

 MANN (see his "Erstes Verzeichn. etc.", p. 22), nor in the Russian Baltic Pro- 

 vinces by Grube (Verzeichn. d. Arachn., Liv-, Kur- u. Ehstl, p. 443 (29)).
