CYCLOSTERNUM.—DAVUS. 4] 
Of this form, of which an immature female is before me, one can say nothing except 
that, for all evidence to the contrary, it may well be the young of some species of 
Eurypelma or other closely allied genus. It is especially to be borne in mind that 
the circular form of the sternum is characteristic of immature specimens of most 
Eurypelmiform spiders.

The type of C. cervinus, which is now before me, is certainly not congeneric with a 
specimen of C. concolor from the Mediterranean, so far as one can judge from an 
immature specimen. But I would not hazard an opinion with specimens not yet 
adult, and I hesitate therefore to tabulate the characters of the female from Mexico.

Without opportunity of examining the type I am unable to offer any opinion as to 
the systematic position of this spider. Neither does Ausserer give any descriptive clue 
as to its identity, save only ‘“‘die Sammtbiirste am innerrande der Schenkel fehlt.” 
DAVUS. 
Davus, O. P.-Cambridge, Biol. Centr.-Amer., Arachn. Aran. i. p. 91 (1892). 
Femora iv. not scopulate on the inner side. Protarsi i. and ii. scopulate beneath in their apical half only. 
Protarsus iv. not scopulate, very spinose. Tibia i. with two short spurs at the apex beneath.

The type of this genus and species is a male, dry, and rather the worse for wear. I
