CAMPODES. 
Campodes C. L. Koch, 1847. 
As has been pointed out in the paper on the Craspedosomatidae, 
this genus belongs to the lulidae. European writers have adopted 
Bollman’s identification of Cryptotrichus with Campodes. Silvestri 
goes so far as to make a family Campodidae, although this name is 
preoccupied in the Thysanura. Cryptotrichus is also preoccupied 
and has been replaced by Cleidogona. In a paper soon to ap- 
pear in the Amefican Naturalist a family Cleidogonidae has been 
recognized, to contain the American genera Cleidogona, Bactropus, 
and Pseudotremia. 
Doratonotus Pocock, 1894. 
This name has been used by Guenther for a genus of fishes, and was 
replaced by Doratodesmus. 
Haplosoma Verhoeff, 1893. 
This name is also preoccupied and was changed to Haplodesmus, 
the family to Haplodesmidse. Verhoeff has also recently published a 
genus of Geophilidae which he calls Haplogaster. Ihis name is at 
least twice preoccupied and may be replaced by Haplophilus . 
Macrotrichus Silvestri, 1896. 
With this name Silvestri proposes to replace Poratia Verhoeff, pre- 
occupied. The deficiency had already been supplied by Mastigona 
Ck., 1895. 
P^ROMOPUS Karsch, 1881. 
This genus is discarded by Silvestri. It is not only valid, but 
should be given family rank under the name Pseromopodidae. 
PlESTODESMUS Eucas, 1 849. 
This genus has been given as a synonym of Platydesmus Lucas, 1 843 , 
but the locality, description, and plates would seem to forbid an infer- 
ence of relationship with Polyzonium Brandt, to which Silvestri has 
reduced it. It is probably a valid genus. 
PSEUDoiUEUS Bollman, 1887. 
This genus is recognized as valid by Silvestri, although Bollman 
established it only as a subgenus and later withdrew it as having been 
based on an immature form *. 
Rhachis Saussure, 1859. 
Preoccupied; replaced by Rhacodesmus Ck., 1895; the only 
species is Rhacodesmus viridis (Saussure). 
Thrinciueus Porat, ,1895. 
The author of this genus takes Acanthiulus murrayi Poc. as his 
type, but applies the name to African species related to those described 
* Bull. 46 U, S. Nat. Mus. p, 138.
