material in the sand normally keeps millepeds out of the sand region. 

 Parajulus is probably a scavenger. 



Order phalangina 



Phalangiinae, sp. (indeterminable). April i.

 specimens were seen in 19 lo, but none were collected. Hart found 

 Liobunum vittatiim Say common on mullein in the Havana region. 



Order araneina 



Xysticiis (/ulosiis Keyserl. ; Emerton, det. April i, 4. 



.V common brown crab-spider, taken hibernating in mullein along 

 the border of a field, and also under a board in bunch-grass southeast 

 of Havana. A widely distributed species, usually found under cover. 

 Other Thomisidae, unlike Xysticiis, are usually found in flowers, 

 where they lie in wait for insect prey. The common genus Misumena 

 is probably represented in sand prairie, in flowers.*
