262 Alexander Pefntiikez'itch, 



male, Nos. 8265 (now No. 92) and 831 1 in the Collection of the 

 Museum of Comparative Zoology of Harvard University and 

 one male, Nos. i. 808 and i. 854 in the Princeton Collection. 

 I have examined only Nos. 320 and 8265. 



Figure 27. — Trlluirus ,:::uy o I i ScuMcr. Specimen No. 8265 (92). Carapace. 

 X 13. 



Scudder's descri])tion of the carapace is not c|uite correct. 

 It is much narrowed in front ( text fissure 2^). The ce])halic 

 area is clearly separated hy the ce])haloth()racic t^Toovc. A longi- 

 ttidinal groove begins at the cephalothoracic groove and runs 

 backwards for a little over one-third of the length of the thoracic 

 area. Neither eyes nor claws can ])e made out. The legs are 

 covered with brown hair. Here and there one can see spines, 

 but these are poorly preserved and barely discernible. The 

 female undoubtedly presents the ventral as])ect, but is so ])()orly 

 preserved that nothing but the legs can be seen more or less 

 clearly. Under such circtunstances it is absolutely imjiossible 

 to say whether the female belongs to the same species with the 

 male. 



The measurements given by Scudder are correct.

One female from Florissant, No. 7177 (now No. 93) in the 

 Scudder Collection of the Museum of Comparative Zoology of 

 Harvard University. 



This specimen is very poorly preserved and the description 

 given by Scudder, as far as can be ascertained, is correct.
