402 Mr. Templeton on certain Spiders. 
Eyes, the anterior pair approximate, leaving no open space, and much 
larger than the other pairs. 
Dysdera Latreillit ?, Blackw. 
Dysdera —————, mihi. 
Being by no means an advocate for the unnecessary establishment of 
new genera, I have merely removed these Spiders into separate divisions, 
the differences being too striking to admit of their being associated to- 
gether, though in habit and form they bear a strong analogy. As I am 
not certain that my species is that described by Dufour or by Blackwall 
I am undetermined as to which division their specimens may beiong. 1 
have however given adrawing and description of mine, so that those 
who may have opportunities of meeting with the Dysd. parvula of Du- 
four and the Dysd. Latreil/ii of Mr. Blackwall may be enabled to 
combine the synonyms, if they all belong to the same species. Dufour’s 
description is “* Thorax smooth, depressed, livid black ; mandibles, palpi 
‘* and feet testaceous rufous; abdomen griseous, hispid,’? which might 
apply to mine; but in his drawing the mandibles are represented of 
half the length of the thorax, and the eyes differ from mine slightly in 
position and magnitude : how far these differences may have arisen from 
hasty examination I am unable to determine, but if the drawing be cor- 
rect, it unquestionably refers to another species. 
In the examination of Spiders a source of inaccuracy arises, which 
requires to be pointed out, and which has perhaps led to the slight dif- 
ference between Mr. Blackwall’s description and that given below. If 
the Spider be examined in the air, the silky hairs lie over each other so 
as to prevent the abdominal macule being at all or clearly distinguish- 
able, and to obviate this, I have uniformly placed the species I sketch 
under water between two plates of glass separated by rings of card, thus 
each hair assumes its natural position and the macule are easily seen. 
Dysdera Templetoni*. 
Dysdera Latreillit ?, Blackw. 
~ Mr: Templeton having omitted to affix a trivial name to this species, the 
Editor has supplied the deficiency by applying to it that of its able observer.
