IG Mr. F. r. Cambrlcljre — A Revision 



(9) Z. genisUe, C. L. Kocli, Germany ; (10) Z. antriada, 

 "Walck., France. 



Ot' these, /"uscrt, Walck., and antriada, Walck. (whicli are, 

 sec. Tliorell and Simon, identical), are no longer available for 

 selection, the former being the tj'pe of Muta ; while albimacu- 

 lata, C. L. Koch, a misquotation for albiviacula, is the type 

 of Zilla and is identical with Z. diodia (Walck.). I am not 

 able to find that any of the remaining six species have been 

 withdrawn under new genera (Jov (]enist(.e,Vj. L. l\..,:=acaluphj, 

 Walck., was not originally included under Mangora, 0. P. 

 Cambr.), or that any type has ever been selected for the 

 genus ; and 1 therefore cite number (3) adophylla, Walck. 

 { = x-7iotaia, Clerck), as distinct from number (4) Z. atrica, 

 Koch, as the type of Nuctohia. 



Type, Nuctohia calophylJa, Walck. (ad ])artem = .r-?Jofa/a, 

 Clerck = ^<V<e;-a/rt, Olivier, the last name having priority, 

 since Clerck's names have been dropped). 



Leucauge, Darwin, in White, Ann. & ^I^^g- Nat. Hist, 

 vol. vii. p. 473 (1841). 



A single species was referred to this genus by Darwin in 

 his ]\ISS. — Leucauge argyrobapta, the specific name being 

 conferred by White. Adam White distinctly says that 

 the generic name was proposed by Darwin, and he gives 

 part of Darwin's original description of the spider, with an 

 account of its web and habit — a horizontal orb-web, with 

 a tangle of cross-threads above and below, the spider hanging 

 underneath the former, its red spots shining like " a ruby with 

 a bright light behind it." No one who has ever been in a 

 tropical Biazilian forest will hesitate one moment in recog- 

 nizing this as a species of the Argyroepeira group of Emerton. 



One feels sorry at the necessity of sacrificing so beautiful 

 a niime ibr the ugly one Leucauge j)roposed by Darwin, but 

 j)riority lies with the latter. 



Type, Leucauge argyrobapta, White, 18 H. — Kio Janeiro.

A single species was originally referred to this name : — 

 A.fogeltuDi, Dol., p. 411. 



For this generic name was substituted by Thoicll (Furop.
