The type and other specimens of this species, together with 

 examples of the equally large Therapliosid Paraphysa mani- 

 cata, Sim., were presented to the Museum by Col. Hayes 

 Sadler, late H.B.M. Consul at Valparaiso. Colonel Sadler 

 kindly furnished me with the following account of their 

 habits : — " With the exception of one specimen [of Paraphysa 

 manicataly which was obtained 20 miles S. of Santiago, these 

 spiders were collected in the grounds at the back of the Hotel 

 Vina del Mar, 6 miles from Valparaiso, in January and
