Sosippus pragmaticus Chamberlin, 1924, Proc. Calif. Acad. Sci., 12:674, fig. 
117. Female holotype from San Carlos Bay, 8 Jul. 1921 (J. C. Chamber- 
lin) in Museum of California Academy of Sciences. NEW SYNONYMY. 
Sosippinus calif or nicus: Roewer, 1954, Katalog der Araneae, 2:313; 1959,

(Lycosidae), p. 1002. 
Structure. For comparison of certain diagnostic measurements of 
S. calif ornicus to other species see Table I. 
Posterior cheliceral margin with three teeth on each side. Of 39 
females examined, 36 had 3-3 posterior cheliceral teeth, two 3-4; of 
23 males, 22 had 3-3 posterior cheliceral teeth. A female and male 
from Mecatan, Nayarit had 4-4 teeth on the posterior margin of the 
chelicerae and two immature specimens from Acaponet, Nayarit have 
the same number. 
In the following table the denotation of tibial spines is from proxi- 
mal to distal end, e.g. 1-2-2 indicates that there is one proximal spine, 
one pair midway of the tibia, and one distal pair; 1-1 indicates one 
spine one-third the length of the leg segment from the proximal end 
and another the same distance from the distal end. Of the 39 female 
specimens

Sixteen females differed from the above only in the ventral spination 
of leg II which was 1-2-2. The five remaining specimens varied in 
different respects. 
Sixteen of the 23 males examined showed the following arrangement 
of tibial spines:

The seven remaining specimens showed variable dorsal spination on 
leg III and the ventral spination of leg II was 1-2-2 in three specimens, 
otherwise the spination was constant except for malformities, e. g. 
regeneration. 
On all legs there appear on the dorsal surface of the tibiae, as well
