brun rougeâtre”. In other respects Lucas’ description accurately corresponds 
with the spider I have mentioned. Should this spider be found not identical 
with C. lapidarius, it may be called C. Corcyreus. 
SIMON (loc. cit.) enters under the genus Cyrtocephalus [-a] a species 
"C. lapidaria RouLin, Ile de Cuba”, which is probably a slip of the pen for 
"C. lapidaria Lucas, Ile de Crète”. He has however not inserted this 
genus in his Catal. syn. d. Aranéides d'Europe. 
The tarsal claws of Cyrtauchenius are 3 in number on each tarsus, 
as in Nemesia. The tarsi of the posterior legs are somewhat thicker towards 
the extremity, almost clublike. The superior or posterior spinners show 
only 3 distinctly separated joints.

The most commonly received name of this genus is not Nemesia, 
but Cteniza, which name is first found in LATREILLE'S Familles Naturelles 
du Règne Animal (1825), where "les Araignées mineuses” are brought to- 
gether under the French appellation "Ctenize". Whether the scientific name 
was intended to be Ctenizus, Cteniza or any thing else, it is not possible 
to see there, for the generie names, even those newly formed, appear 
in that work only in their French form, whence also follows (Conf p. 4 
note 1), that any right of priority cannot be claimed for the generic names 
there proposed. It is true that BERTHOLD, in his German translation of LA- 
TREILLE'S Familles Naturelles (1821), gave a Latin form to these new generie 
denominations 7), and in the cases, in which he was the first who did so 
1) He however calls LATREILLE’S "Otenize" not Cteniza, but Ctenize, as the ge- 
nus is also called by for inst. SUNDEVALL (Consp. Arachn., p. 28). That LATREILLE'S 
meaning was, that the name should end i a, is visible in his subsequent works, as 
e. g. in the edition of Cuvier’s Règne Animal published in 1829, and it has since 
generally received that termination.
