of the posterior marginal lobes, in the dorsal sculpture, and in the 
copula tory legs, which are in Trichopeltis said to be so large and so 
deeply inserted that the legs of the sixth and seventh segments are 
widely separated to accommodate them. Otodesmus watsoni is from 
upper Burma, while Tfichopeltis bicolor is from Sumatra, and has the 
anterior and and poriferous (?) carinae dark, the others yellowish. 
Family STIODESMID^, nov. 
Returning to the African and' West Indian Cryptodesmoidae, we 
find genera which suggest certain members of the Hercodesmidae» 
but differ distinctly in that the last segment is not reduced and con- 
cealed in the nineteenth. Such are Stiodesmus Ck., from Liberia, 
and Cynedesmus Ck., from Grand Canary. In the last genus it 
seems to be possible to include Cryptodesmus ornamentatus Ksh., 
from Cuba. A specimen from Florida is more slender than Cynedes- 
mus, and the pores occur only on segments 5, 7, 9, 10, 12, 13 and 
15. This has been given the name Psochodesmus crescentis * . 
The Javan genera Pronodesmus and Myxodesmus may also be 
placed here, although in habit they bear a very striking resemblance 
to such Hercodesmidae as Udodesmus and its allies. Lophodesmus 
Poc. doubtless also belongs in the Stiodesmidae ; at least it seems 
to resemble Stiodesmus and Cynedesmus more than do Pronodesmus 
and Myxodesmus.

In this case the relationship to Cryptodesmus is doubtful, but the 
location of the pores in the anterior part of the segments is at least a 
suggestion of such afiinity, and the structure of the copula tory legs 
is somewhat similar to that of the Pterodesmidse. From a cave in 
Jamaica I have specimens of a genus related to Comodesmus. 
Genus Inodesmus, nov. 
Differing from Comodesmus in the somewhat more slender, monil- 
iform body, obsolete caring, more projecting last segment, and normal 
pore-formula, the pores located in shallow depressions in the lateral 
middle of the segments, not in front of the middle as in Comodesmus. 
The only known species, /. jamaicensis , is about equal in size to Como- 
desmus lanatus, and is lighter brown in color, but may be faded. 
* Psochodesmus CRESCENTIS, sp. n. First segment with horizontal rim very 
narrow ; dorsal granules less pronounced than in Cynedesmus ; carinse 
narrower; color light brown ; length 4.5 mm., width ,6 mm.; locality 
Crescent City, Florida. Collected by Mr. H. G. Hubbard, of the U. S. 
Department of Agriculture.
