HORIZONTAL SNARES AND DOMED ORBS. 
In this connection it should be remembered that there is a general resem- 
blance in structure between the Orbweavers and Lineweavers; and it may be 
stated, moreover, that this resemblance is more marked in the case of the 
genus to which Basilica is closely related, Meta; and also in some of those 
species which have the habit of making a composite snare. This is so strik- 
ing in Koch’s genera Meta and Zilla that they have been classed with both 
sections. On this point Dr. T. Thorell has remarked, “As Zilla shows an 
analogy with Steatoda of the Lineweavers, so does Meta form a transition 
to Linyphia of the same tribe.”! These relations may be more fully con- 
sidered in the systematic part of this work, but in the meantime we are 
justified in saying that in the case of the above named species, we find the 
tribes of Orbitelarize and Retitelarie approaching each other in structure 
as well as in the interblending of their spinning habit.
