12 OXYDESMIDJ^. 
17. OxYDESMUs FLAvoMARGiNATUs (Peters) ; “America?”; Berlin Museum. 
18. OxYDESMUs FUAMBO, sp. fi. Segments with the surface granular-uneven, 
the areas rather distinct ; tubercles distinct, though slightly promi- 
nent, scarcely more so than in O. Icevis ; last segment with the apex 
squarely truncate, on each side three tubercles projecting from the 
strongly converging margins ; carinse with very entire and evenly 
rounded margins ; copulatory legs differing from those of all other Oxy- 
desmi in that the lamella is bent backward (downward) at a right angle ; 
the apex is then curved forward and has distally a deep rounded notch ; 
the lamella is not ’iserted under the edge of the aperature as in the 
other species, but lies on it, while the slender ramus is inserted as usual ; 
color black, shading into reddish ; the carinse bright yellow, and a dull 
yellowish median spot along the posterior margin of each segment ; 
length 45 mm,, width g mm. ; locality Fuambo, near Lake Tanjanika ; 
British Museum. 
19. OxYDESMUs GRANULOSUS (Beauvois) ; Oware. 
20. OxYDESMUS GRAYii (Newport) ; Sierra Leone : British Museum. 
21. OxYDESMUs jOHNSTONEi, Sp . H. Vertex with two large prominences, the 
summits of which are hirsute with long hairs ; segments rugulose, the 
areas well defined, the tubercles large ; submarginal ridge sharp and 
prominent, close to the finely and widely serrulate edge ; pores in a deep 
depression in the middle of the submarginal ridge ; last segment 
rounded and not emarginate at apex ; copulatory legs without the prox- 
imal branch or process of O. grayzi ; color black ; length 80 mm,, width 
12 mm, ; Rio del Rey ; British Museum. 
22. OxYDESMUs L^:vis, Sp. 11. Similar to O. afer, but smaller and smoother. 
Segments dorsally indistinctly coriaceous, not granular, apparently 
smooth and shining ; tubercles obsolete ; carinse evenly rounded, the 
ridge moderately broad and high ; color nearly black, with the lateral 
half of each carina yellow, antennae and legs blight pinkish ; length of 
male 53 mm., width 9.5 mm, the anterior segments widest; Togo 
Colony, apparently common ; Berlin Museum. 
23. OxYDESMUS LIBER Cook ; Liberia ; Berlin Museum. 
24. OXYDESMUS MEDius Cook ; Liberia; Berlin Museum. 
25. OxYDESMUS THOMSONii (Lucas) ; Liberia; type in Paris? 
26. OXYDESMUS TOGOENsis Cook ; Togo Colony ; Berlin Museum. 
27. OXYDESMUS TRicuspiDATUS (Peters) ; Guinea ; Berlin Museum. 
28. OXYDESMUS TUBERCULiFRONs Porat ; Kamerun ; Stockholm Museum. 
29. OXYDESMUS vALDAUi Porat ; Kamerun ; Stockholm Museum. 
30. OXYDESMUS viTTATUs, Sp . 11 . Segments with three rows of rather large 
tubercles ; snbmarginal ridge moderate, not sharp above ; lateral margin 
entire ; color dark brown, a median stripe of light coffee-and-milk 
brown, broader on posterior subsegments and occupying nearly half the 
width of the subsegment; length 70 mm., width ii mm. ; Cameroons 
and Old Calabar; British Museum. 
31 OXYDESMUS XANTHOMELAS, sp. It. Evidently nearest related to ( 9 , 
differing in the very slightly development of the low, rounded, tubercles 
and in the possession of a broad, rectangular, median yellow spot occu- 
pying the posterior half of that part of the dorsum : length of female 
65 mm., width 11.5 mm, ; Kilmanjaro ; U. S, Nat. Museum.
