Tertiary Spiders and Opilioiiids. 243 



enlarged owing to the presence of an apophysis. The patella of 

 the pedipalp has also an apophysis and is besides provided with 

 four spines. The structure of the copulatory apparatus itself is 

 not distinct, but appears as a dark area with curved edge possibly 

 representing" a long curved embolus. Legs in order 1423. 



The female is very poorly preserved and it is impossible to 

 decide whether she actually belongs to the same species. 



Eostentatrix cockerelli n. sp. {Text figure 14). 



One female from Florissant in the collection of T. D. A. 

 Cockerell of the University of Colorado. 



The specimen is well preserved and shows the ventral surface 

 with the outline of the carapace impressed over the coxse. Total 

 length II mm. Carapace 3.1 mm. long, 3.1 mm. wide, subrotund. 

 Abdomen 5.5 mm. long. 4.8 mm. wide, joined to the carapace by 

 a long petiolus. Chelicerte week, slightly divergent. Pedipalpi 

 slender and somewhat longer than carapace. Legs in order 1423. 

 First leg — 16. i mm. long, second — 15.0 mm., third — 12.8 mm., 

 fourth — 15.9 mm. They are clothed with simple hair. Strong 

 spines are present on all legs, but they are not numerous, nor can 

 their arrangement be made out clearly. The spinnerets are 

 approximated, the posterior ones longer than the anterior ones, 

 clothed with simple hair, but spinning tubes indiscernil^le. The 

 body is also covered with simple hair which is long and brown in 

 color. Nothing else can be made out. 



FAMILY PARATTID.E, NEW. 



A family of extinct spiders of the sub-order Arachnomorphae, 

 division Ecribellatas and sub-division Entelegynse, having a gen- 

 eral resemblance to Attids and jumping Clubionids and probably 

 closely related to both. In absence of other tangible characters 

 on account of the poor preservation of the specimens, the family 

 may be characterized by the arrangement and proportion of the 

 eyes, as described for Paratfits oculatus, the main points being, 

 that the eyes are round, in two rows of four eyes each, anterior 

 eyes subequal and fairly equidistant, posterior eyes considerably 

 smaller, the posterior median eyes situated between and slightly 

 behind the anterior median eyes.
