Bothriocyrtum calif ornicum, Cambr. (Cteniza). In ^logg., 

 Harvesting Ants and Trapdoor Spiders, II (Supp.), 1874. 



This is the well-known trapdoor spider of Southern California, 

 whose thick, bevel-edged trapdoor and nest is commonly sold by 

 natural history dealers. The species was probably more or less 

 common in the Santa Clara Valley, before the days of plowing and 

 cultivation. I have been unable to find any trace of it since my 

 searchings began. Dr. Jenkins reports the finding of a nest on his 

 Cedro Cottage premises, sometime about i8go. The specimen is 

 supposed to be deposited with the Entomological Museum of the 

 University, but unfortunately there seems to be no specimen here 

 labeled as such. . It maA^ be one of two unlabeled specimens 

 that are here. The only other report that I have come across is in 

 Science, III, 62, Notes and News, p. 476 (1884), which, however, 

 states that a new Cteniza has been found at San Jose, different 

 from the one found in Southern California, and may, indeed, refer 

 to something else. As it gives no reference, the report is probably 

 worthless. Bothriocyrtum, however, probably persists yet in 

 some isolated, uncultivated areas in this county, and may be 

 expected to come to light at any time in the future.
