is twice as long as the sixth. Neither of these statements will apply 
to any of the Kamerun Pterodesmidse known to me. Porat also 
describes the coxae as produced, but his figures show that the sterna 
are intended. 
*The Kamerun Pterodesmidae of the Berlin Museum are as follows : 
COMPSODESMUS PERLATUS Cook ; Jaunde Station. The larger of two new 
female specimens from the same locality. Measures 23.5 mm. by 8 mm. 
CoMPsoDESMUs LiMACiNus, sp. H. Strongly and uniformly convex, the carinae 
decurved in the direction of the dorsal arch ; all carinae somewhat fal- 
cate, with the posterior corners sharp and produced caudad ; sterna 
sparsely granulate, deeply impressed ; on posterior segments the sternum 
of the posterior pair of legs bears two conic processes, distinct on the 
sixteenth segment, long and devaricate on the seventeenth, small, 
pointed and approximate on the eighteenth. Color in alcohol horn 
brown, moderately light; length 33 mm., width 10 mm.; Jaunde 
Station, Coll. Zenker, a single female specimen. This is the largest and 
broadest known member of the Pterodesmidse, though C. perlatus is 
broader in proportion to its length. The size and more convex dorsum 
render C. limacinus strikingly distinct from all related forms. 
COMPSODESMUS CUPULIFER, Sp. H. Dorsum flat, scarcely convex in the middle, 
the carinae horizontal ; anterior segments with posterior corner scarcely 
produced ; sterna scarcely granular or pilose, without conic processes ; 
copulatory legs much as in C. pulcher Ck., short and simple, with a 
large distal cup-like excavation ; color dark brown above, whitish below ; 
length 26.5 mm., width 7.5 mm. ; locality Barombi Station. 
COMPSODESMUS SPINATUS, Sp. 71 . Dorsum nearly flat, the median convexity 
greater than in cupulifer, less and narrower than in perlatus, with which 
there is agreement in outline and in the strongly falcate carinte; the ra- 
diating and other dorsal areas are somewhat more convex than in perla- 
tus, but not so heavily pigmented as in that species; posterior sterna 
(13-18) distinctly spined, the spines of segments i6 and 17 largest, the 
spines generally somewhat better developed than in perlatus, in which 
the same segments bear spines ; preanal scale with setiferous tubercles 
shorter than in perlatus; length 18.5 mm., width 6.5 mm.; Barombi 
Station. The copulatory legs are much as in perlatus, with the distal 
excavation deeper and the posterior spine slightly less developed. 
COMPSODESMUS KUAKO Sp . 71 . Perhaps doubtfully referable to the present 
genus ; differing from the other species in the more slender form and 
somevvdiat deficient dorsal sculpture. The copulatory legs are very sim- 
ilar to those of the last species, but lack the spine at the posterior corner 
of the apical excavation. Dorsum somewhat convex in the middle, the 
carinae distinctly ascending so that their margins are as high as the 
middle of the dorsum ; three rows of convex areas on the convex 
median portion ; carinae smooth except for the radiating marginal im- 
pressions ; pores distinct ; sterna narrow, very minutely roughened and 
pilose, scarcely produced caudad. Color translucent whitish in alcohol, 
apparently unpigmented and probably white in life, as in Gypsodesmus; 
length about i8 mm., width 4.5 mm, ; "'‘Kuako bis Ki77ipoko,''' Congo, a 
single male specimen collected by Buettner. This is the only member 
of the Pterodesmidae yet known from the Congo Valley.
