THE TEXAN KCENENIA. 
AUGUSTA RUCKER. 
Tuis most interesting microthelyphonid was discovered last 
May in the neighborhood of Shoal Creek, near Austin, Texas, 
under stones in company with Campodea, Japyx, and Scolopen- 
drella. A short description of it was given by Dr. W. M. 
Wheeler in the November Naturalist, under the title ** A Singu- 
lar Arachnid (Kenenia mirabilis Grassi) occurring in Texas.” 
The writer believed the Texas species to be identical with the 
Sicilian one figured and described by Drs. Hansen and Sorensen, 
and therefore wrote of it under that name. A number of speci- 
mens have since been examined zz fofo and in sections, and 
some interesting results have been obtained. It did not seem 
Probable that the Texan Koenenia had been imported, yet it 
Seemed less probable, though our climate is much like that of 
Southern Europe, that the two species were identical. Close 
‘Microscopic examination has shown them to be two distinct 
. Species of the family Kæneniidæ. 
Kenenia has since been found in Siam and Paraguay and, 
like all archaic types, it will doubtless be found to be cosmopolitan
