RICHARDSON] TERRESTRIAL ISOPODS OE FAMILY EUBELIDJE 243 



elites of the second and third segments are present on the anterior 

 portion of the underside in the form of a sharp ridge, more promi- 

 nent and thicker on the second segment. 



The first two segments of the abdomen have the lateral parts 

 covered by the seventh thoracic segment. The lateral parts of the 

 three following segments are well developed and directed back- 

 ward. The third and fourth segments are a little longer than the 

 first, second, and fifth segments, which are subequal. The sixth 

 or terminal segment is triangular at the base, with the apex produced 

 in a long triangular process, the sides of which converge gradually 

 to a rather acute extremity. The basal article of the uropoda is 

 quadrangular in shape, and occupies all the space between the lateral 

 angles of the fifth segment and the apical process of the sixth seg- 

 ment. It extends to the extremity of the lateral angles of the fifth 

 segment, but not to the extremity of the apical process of the sixth 

 segment by some little distance. The posterior margin is excavate 

 between the produced lateral angles, the inner angle being a little 

 narrower and more acute than the outer one. The outer branch of 

 the uropoda is large, conical, and extends a little beyond the apical 

 process of the sixth abdominal segment. The inner branch just 

 reaches the tip of the apical process. All the legs are ambulatory. 



Only one specimen was collected by Dr. O. F. Cook at Mt. Coffee. 

 The type is in the possession of Dr. O. F. Cook. 



ETHELUM LIBERIENSIS, sp. nov. 



Bod}- very convex, contractile into a ball. Surface smooth, with 

 a tiny pearl-like granulation on either side of the second, third, 

 sixth, and seventh thoracic segments and the third abdominal 

 segment. Color, grayish brown, with wavy lines of yellow on either 

 side of the median longitudinal stripe, and with a large yellow spot 

 on either side of the second thoracic segment at the lateral margins. 

 Uropoda yellow, as well as the first three articles of the peduncle of 

 the second antennae. Head wider than long, with the front straight 

 and not margined, but continuous with the epistome, which is pro- 

 duced in a convex tubercle. The eyes are small, composite, and 

 situated at the lateral margins. The first pair of antennae are 

 rudimentary and inconspicuous. The second pair have the first arti- 

 cle short; the second is twice as long as the first: the third is as 

 long as the second; the fourth is equal in length to the third; 

 the" fifth is but little longer than the fourth. The flagellum is 

 composed of two articles, the second of which is more than twice as 

 lone as the first.
