Richardson] TERRESTRIAL ISOPODS OF FAMILY EUBELID^ 223 



deep and are unequally cleft, the inner portion being the smaller. 

 Coxopodites are also present on the underside of the second and 

 third segments at the anterior portion of the lateral margin in the 

 form of thickened ridges, more acute and toothlike on the second 

 segment. 



The first five segments of the abdomen are about equal in length. 

 The lateral parts of the first two are covered by the seventh thoracic 

 segment. The lateral parts of the three following segments are 

 well developed and extend backward, those of the fifth segment 

 reaching the extremity of the basal article of the uropoda. The 

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

 produced in a widely quadrangular process, with truncate extremity 

 and parallel sides. It is 4^ mm. long. The width of the apical 

 process is 23^ mm. The width of the segment at the base is 7 mm. 

 The basal articles of the uropoda occupy all the space between the 

 apical process of the terminal abdominal segment and the produced 

 lateral parts of the fifth segment and extend to the extremity of 

 the apical process. The basal article is somewhat quadrangular in 

 shape, with the posterior margin deeply excavate in the middle, 

 on either side of which the post-lateral angles extend in the form 

 of rounded lobes. Close to the external margin of the basal article 

 is a well-defined and most-pronounced carina extending the entire 

 length of the article. The outer branch of the uropoda is large, 

 conical in shape, is inserted in the posterior excavation of the basal 

 article, and extends half its length beyond the lateral angles. The 

 inner branch does not reach by some distance the extremity of the 

 terminal abdominal segment and is not visible in a dorsal view. All 

 the legs are ambulatory. 



More than forty specimens were collected by Dr. O. F. Cook 

 at Mt. Coffee and Muhlenberg Mission. About ten more were col- 

 lected by Mr. R. P. Currie, one by Mrs. Sharp, and one by Mr. 

 Collins, in the same locality. 



The type is from Mt. Coffee and is in the possession of Dr. O. F. 

 Cook. 



The co-type, collected at Mt. Coffee by Mr. R. P. Currie, is in the 

 U. S. National Museum. Cat. no. 38,526. 



MESARMADILLO SIMILIS, sp. nov. 



Body ovate, a little more than twice as wide as long, convex, 

 contractile into a ball. Surface smooth, with a small, pearliform 

 granule on either side of each one of the thoracic segments. Color, 

 brown, with wavy lines of yellow, on either side of the median stripe
