of the Genera of tlie Aiauccc. 45 



Ckratinopsis, Emerton, Ti-ans. Conn. Acad. vol. vi. p. 36 

 (1882). 



Four species were orio'inally referred to this genus : — 

 (1) Eriqone interpres, O. P.-(/ambr. ; (2) Cerntinopsis nigrl- 

 c(-ps, Emert. ; (5) C. laticeps, Emert. ; (4) G. nigripalpis, 

 Emert. 



I cannot find that any of these species have ever been re- 

 moved to a new ^enus, but the type was definitely selected 

 by Simon (Hist. Nat. Ar. ii. p. 673, 1894), G. interpres, 0. P.- 

 Cambr.). 



Type, Geratinopsis interpres (0, P.-Cambr.), 1874. — 

 N. America. 



Geammonota, Emerton, Trans. Conn. Acad. vol. vi. p. 38 

 (1882). 



Three species were originally referred to this genus; — 

 (1) Erigone pictilis, O. P.-Cambr. ; (2) Erigone ornatciy 

 O. P.-Cambr.; (3) G. inornata, Emert. 



1 cannot find that any of these have ever been removed to 

 a new genus, but the type was definitely selected by Simon 

 (Hist. Nat. Ar. ii. p. 666, 189i) , Erigone pictilis, 0. P.-Cambr. 



Type, Oramrnonota pictilis (O. P.-Cambr.), 1875. — N. 

 America. 



Spiropalpus, Emerton, Trans. Conn. Acad. vol. vi. p. 39 

 (1882). 



A single species was originally referred to this genus — 

 Spiropalpus spiralis, Emerton. 



Type, Spiropalpus spiralis, Emerton, 1882. — N. America. 



L*IPL0STYLA, Emerton, Trans. Conn. Acad. vol. vi. p. Qo 



(1882). 



Three species were originally included which must be taken 

 into consideration in the settlement: — (1) Linyphia concolor, 

 Wid.; (2) Bathgphaates nigrinus (Westr.); (3) Diplostgla 

 canadensis, Emert. 



None of these have, so far as I can ascertain, been removed 

 to new genera, nor has the type of Diplostyla been selected, 

 and I here select L. concolur, Wid., as tlie type. Diplo- 

 stylus, not Diplostyla, is preoccupied by Salter for Crustacea, 

 1863. 



Typp, Di2>lostyla concolor (Wid.), 1834. — Europe.
