1006 REY. 0. P. CAMBRIDGE ON NEW [Dec. 15, 
5. On some new and little-known Spiders (Araneidea). 
By the Rev. O. Pickarp Camprineg, M.A., F.R.S., &c. 
[Received October 16, 1896.] 
(Plate LIT.) 
The four Spiders described below are from widely separated 
localities—Ceylon, Borneo, and South America. For two of them 
(of the families Myrmecide and Gasteracanthide) it seems to me 
that two new genera are needed. Of the other two the females 
have already been described, but the males, now described and 
figured, are new. The Spider on which one of the new genera is 
based—Friula (Gasteracanthide)—is of exceptional interest; it 
was received by me many years ago from the collection of the late 
Mr. Wilson Saunders, with an almost illegible, and to me wholly 
unintelligible, little ticket attached to it, so that I neither knew 
the name of the captor nor the locality. Not long since I had an 
accidental clue to it which on being followed up resulted in these 
particulars being cleared up, and there is no doubt that this 
Spider was found at Sarawak by Dr. A. R. Wallace. It is with 
much pleasure that I have now conferred upon this singular 
form the name (so well known and valued by every biologist) of 
its captor. 
Order ARANEIDEA. 
Gen. nov. Arrius (fam. Myrmecide). 
Cephalothoraz much longer than broad; lateral marginal 
impressions at the caput slight; fore margin broadly but slightly 
roundly truncated. Posterior extremity rather drawn out into 
a somewhat tapering but truncated covering to the fore part of 
the connecting pedicle, which last is long, cylindrical, and corneous. 
Upper convexity moderate, profile slightly and uniformly curved ; 
normal grooves and indentations very slight. 
Eyes widely separated, in two transverse curved rows; the 
anterior row much the shortest and very slightly curved, the 
convexity of the curves of both rows directed forwards; the 
posterior row is double the length of the anterior and strongly 
curved. The four central eyes form a quadrangle broader than 
long, and its fore side shortest. The four laterals form a very 
large quadrangle whose relative proportions are similar to those 
of the central one, and the line formed by the laterals on each 
side is rather longer than that of the anterior row. The fore- 
central eyes are largest, the hind-laterals (apparently) the 
smallest. . 
Legs not very long; rather slender, not very unequal in size, 
4,2,1,3. Spines few and slender. Tarsal claws 2, with a small 
claw-tuft on a supernumerary or claw-joint. 
Palpi short, slender; digital joints as long as, or a little longer
