A Levision of the Genera of the Aranes. 481 
XLVIT.—A Revision of the Genera of the AranEes or Spiders, 
with Reference to their Type Species. By Frupx. Pickarp- 
CamsBrives, B.A., F.Z.8. 
Tuts sixth instalment of the series commenced in the Ann. 
& Mag. Nat. Hist. ser. 7, vol. vi., for Jan. 1901, includes all 
the genera founded by Walckenaer in the ‘Tableau des 
Ayranéides,’ published in 1805, and in addition three other 
genera published by Latreille in 1806 and 1809, Gen. Crust. 
Ins. 1. p. 109, and op. cit. iv. p. 371, the two in the latter 
volume being here attributed to Walckenaer on the grounds 
that Latreille was merely publishing Walckenaer’s “‘ Manu- 
scrit communiqué,” according to the former’s express 
statement, 
Corrigenda. 
1. Aryeus. 
In Ann. & Mag. Nat. Hist., Jan. 1901, p. 57, under Atypus, 
the words ‘‘ which Latreille identified by mistake as belong- 
ing to this genus” should be deleted. The facts are more 
correctly stated thus :—Rcemer fancied, though erroneously, 
that his species was congeneric with Aranea aquatica, Fabr. 
But there is no possible doubt that his figure represents an 
adult male of some species of Atypus. It is, however, im- 
possible to say now which of the three European forms is 
represented by the name subterranea, or indeed by any of the 
earlier names, piceus, difforme, or Sulzeri. 
The type of Atypus would, however, be more correctly 
quoted as Atypus subterraneus (Roemer). 
2. CERATINELLA. 
In Ann. & Mag. Nat. Hist. (7) vol. xi., Jan. 1903, p. 44, the 
type of Ceratinella, Emerton, is there given by a slip of the 
pen as C. brevis (Wider). This is, of course, incorrect, since 
this species was not originally included in Emerton’s group, 
and cannot serve as the type. I therefore here select Cera- 
tinella Emerton (O. P.-Cambr.) as the type of the genus 
Ceratinella.
