710 riiOCEEDINGS OF THE XATIOXAL MUSEUM. volxxi. 



Process of segment 6 densely hirsute distad; the apex prominent, 

 rounded, nearly as large as the prominent shoulders, below which the 

 process is distinctly narrowed. 



Seventh segment with posterior rim of aperture very deeply, broadly, 

 and abruptly excised, leaving two sharply angled, thin processes, 

 one at the base of each of the normal legs. 



Process of segment 15 constructed exactly as in the other large gen- 

 era, such as Astrodesmus ; rounded at apex and distinctly canaliculate 

 medianly to near the apex. 



Legs of male hirsute with long hairs, the anterior more hirsute than 

 the posterior and somewhat more crassate, the ventral face of the four 

 distal joints tuberculate; the tieshy soles of the first six pairs are well 

 developed, with the claws much reduced. 



Copulatory legs (Plate LVII, figs. 3a-3c.) 



Color of alcoholic specimen pale grayish brown, the posterior margin 

 of each segment with a very narrow transverse band of deep brown; 

 legs and antennje pale. The specimen may not have reached its full 

 coloration after having molted. 



Length, 50 mm. ; width, with carinie, 9.8 mm. ; without carinae, 6.2 mm. ; 

 length of antennte, 7.6 mm.; of leg from segment 10, 0..3 mm. 



Locality. — Mundame, Kamerun; a single male specimen collected by 

 Conradt is in the Berlin Museum. 



TYMBODESMUS VIDUA, new species. 



Another Kamerun specimen, possibly a female of the preceding 

 species, is much more convex than the last and has the terminal seg- 

 ments more exposed. The cariuic are proportionally much narrower and 

 the calli are so tilted that the pores face nearly laterad. The coxsa of 

 the second pair of legs are produced into long conic-cylindric, pointed, 

 and divaricate processes; the ventral rim of the third segment is deeply 

 and broadly emarginate, as in the genus Gomphodesmus. 



Length, 53 mm.; width, with carinsc, 10.4 mm.; without carinte, 7.5 

 mm.; length of antenna^, 7 mm.; of leg from segment 10, 7.5 mm. 



Color distinctly darker than that of the male specimen. 



Whether this is in reality the female of Jif/liniis can not be determined 

 until the Kamerun region has been more thoroughly explored. For 

 the present I am inclined to treat it as distinct on the ground that the 

 much greater convexity of the body and the lateral position of the pores 

 are difierences greater than known to exist between the sexes in the 

 present family, and minor differences in the conformation of the first 

 and last segments seem to sup]>ort the supposition of specific distinct- 

 ness. The anterior segments are even more strongly convex than the 

 others, and the first, while narrowed at the lateral angle, as in Jiglinus, is 

 broader farther laterad, so that the final convergence of the sides is 

 more abrupt than in the other specimen. From above the marginal 

 calli appear much narrower than in fiylinus on account of being turned
