appearance of the animal, the position of the eyes and the structure of the 
mandibles, are the same in Spermophora as in Rachus, as may be seen by 
a glance at the figures given by Lucas), Ducks?) and HENTZ?) Only 
the legs appear to be somewhat shorter in proportion in the American than 
in the European and North-African species. Even their industry and the 
form of their webs are the same. Generically they cannot possibly be se- 
parated, and, as the name Spermophora has the right of priority, it must 
be preferred to Rachus (and Oophora). — In a paper that has lately ap- 
peared 5), SIMON unites this genus with Pholcus, in spite of the difference 
in the number of eyes, a proceeding which I can by no means approve.

This genus, whieh, as we have above mentioned, originally included 
also WALCKENAR'S Pholcus and Theridium, was reduced by WALCKENAER 
loc. cit. so as only to comprise the species that typified the genus, S. tho- 
racica LATR. WALCKENAER afterwards enlarged it again so, that according 
to his characteristics, it corresponded with the whole of our sub-family Scy- 
todine. We take it in the compass first assigned to it by WALCKENAER, 
and also adopted by Simon, namely, as answering to the "1" Fam., les 
Gibbeuses, Gibbose” of Scytodes WALCK. in H. N. d. Ins. Apt., I, p. 270. 
The superior tarsal claws are large, weak, equably curved, with 
about 6 or 7 long, strong saw-teeth, proceeding from one side of the
