IK criatututij Black w., is not tiie type of Ih'plocepliahtfi^ 

 Beitkau, as stated by Simon (Hist. Nat. Ar. ii. p. G;37), but 

 J K for ami /lifer ((). P. (/ambr.). II'. acumimita was seljctinl 

 as the type of Walck naen'a by Tliorell in ]<S(iy, l)ut it bad 

 abeady been witlifbawn by Simon in ISG-l. 



A. nionocerosj Wid., wms quoted by Menge as the type of 

 his genus Coniicularia in 1869, but his descriptiou aud 

 tigures do not represent this species, but W. unicornis^ Cauibr., 

 sec. Thorell and Simon; and A. rnonoceros, VVi b, was in 

 1884 lefened by Simon to his genus Prosopot/teca, and subse- 

 quently (Hist. Nat. Ar. ii. p. G6'2) selected as the type. 



We can account, then, for the genera and species involved 

 as follows : — 



VValckenakhia, Blackw., 18o3. — Type, IT. cristata^ 

 Blackvv. 



AkkecEKUS, Simon, 1864. — Type, A. camelinus = acumina- 

 tus, Blackw. 



CoRNlCULARlAjMenge, 1809. — 'Ty pe,C. unicornis {dimhv.). 



DlPLOCEPHALUS, Bertkau, 1884. — Type, D. foraminifer 

 (Cambr.). 



ProsopoTHECA, Simon, 1884. — 'J ype, P. monoceros (Wid.). 



Nekiene, Blackwall, Lond. Edinb. Phil. Mag. 3, iii. p. 187 

 (Sept. 1833). 



Three species were originally referred to this genus: — 

 (1) N. marginata, Blackw.; (2) N. rubens, Blackw.; (3) N. 

 curnitta, Blackw. 



The genus was first broken up when the second species, 

 N. rubena, was removed under Aryus by Walckenaer under the 

 name A. cheliferus in 1841, and subsequently again removed 

 in 1868 under Gonatiuni by Menge under the name G. chtli- 

 /erM;», which, sec. Thorell, Simon, and Kulczynski, = iV. rubi-nsj 

 Blackw. 



The third species was renioved under Dicf/phus by Menge 

 in 1869 under the name D. ciluncidux, which, sec. I'iiorell 

 and Simon, = A^. cornuta, Blackw. 



aV. manjinata is thus left in as the type of t'le genus, and, 

 sec. Thorell, Simon, and Kulczynski, this species = /></* j//?/a'a 

 cl'ithrata, Sundevall. Neriene will thus follow the fortunes 

 of this species, for no type had ever been definitely selected 

 for Nericne until Noveml)er 1900, when the Rev. O. Pickard 

 Cambridge (' List ot British and Irish Spiders,' p. 41 J re- 

 ferred one tipeeie8, A\ ruben'ij to the genus witli the words
