6. Physogaster tomentosa, Gu^r. 



Found in great abundance under stones near tlie town of Co- 

 piapo. North Chile.

 ground under them, near Valparaiso.

9. Nyctelia Icevis, Waterh. 



Found on the east side of the Andes in Valle Hermosa, about 

 nine leagues from the volcano of Peteroa, amongst herbage in

 shine, and makes its appearance in the evening ; if the weather 

 be dull it will crawl about in the day.

Habitat believed to be the same as the last, but not quite cer- 

 tain.

 group ; but the average size of the individuals is between that of
