 COLLECTED IN LIBERIA BY DR. O. F. COOK

Under the auspices of the New York State Colonization Society, a 

 large collection of terrestrial isopods was made in Liberia during 

 the years 1893 to ^95 by Dr. O. F. Cook, custodian of Myriapoda 

 in the U. S. Department of Agriculture. Most of the specimens 

 were collected at Mt. Coffee, at an elevation of three or four hun- 

 dred feet. This mountain is just above the point of navigation of 

 the Saint Pauls River. Other specimens were collected at Muh- 

 lenburg Mission, at Monrovia, and at Sierra Leone. The collections 

 were made in the spring of the year, from January to May. 



Through the kindness of Dr. O. F. Cook, the terrestrial isopods 

 were given to me to study. I wish here to express my gratitude to 

 Dr. Cook for this privilege. The present paper is the result of 

 my study on one family in this collection, the Bubelida. All the 

 specimens collected represent new species, and a new genus is added 

 to the live genera already known. 



It may be noticed that the general figures do not seem to corre- 

 spond with the detail drawings. This lack of correspondence is due 

 to foreshortening in the general figure, caused by the convexity of 

 the specimens. The detail figures give a different perspective.
