HAPLOSOMIDJE.

by Karsch under Glyphiulus which according to Pocock is related to 
Trachyiulus Peters. Acanthoiulus is one of the Spirobolidse, and 
Thrinciulus must stand as a synonym, unless murrayi proves to be 
generically distinct from hlainvillei lycGuillou. At any rate, Thrinci- 
ulus will be a genus of Spirobolidae, while Porat’s Kamerun species 
are to be included in a genus Tophostreptus based on L. magnus 
(Karsch) ; I have compared the type with several specimens from 
Kamerun. The other species of Glyphiulus described by Karsch, 
G. scalatus, is the type of a related genus to be called Anastreptus. 
Trachysoma Attems, 1895. 
This name is preoccupied and has been replaced Trachygona ;• a 
family Trachygonidae has also been recognized. 
Verhckffia Broelemann, Dec. 1895. 
This name was given to supply the place of Tatzelia Verhoeff, but 
Haplogona Ck., proposed for the same purpose was already printed 
(Oct. 1895). 
The synonymy of some of the families recognized by Silverstri is 
as follows: Trachysomidae vSilvestri=Trachygonidae Ck. ; Canipodi- 
dae Silvestri=Cleidogonidae Ck. ; Trachyiulidae Silvestri, 1896= 
Cambalopsidae Ck., 1895 ; Nemasomidae Silvestri, i896=Isobatidoe 
Ck., 1895; Pyrgodesmidae Silvestri, 1896 = Sty lodesmidae Ck., 
1895 (probably); Gervaisidae Silvestri, 1896 = Gervaisiidae Ck., 
1895; Haplosomidae Silvestri, 1895 = Haplodesmidae Ck., 1895; 
Sphaerotheriidae C. T. Koch, i847=Zephroniidae Gray, 1842. 
Family CYCLODESMIDZB Silvestri, 1895. 
If we are to follow this author, his family must be reduced 
to Oniscodesmidae Saussure, i860, for Oniscodesmus is one of four 
genera which he includes in it. The others are Cyclodesmus, Cyrto- 
desmus, and Doratonotus (=Doratodesmus). After an examination 
of all four genera I am convinced that there is no family relationship 
unless it lies between Oniscodesmus and Cyclodesmus. On Cyrto- 
desmus and Doratodesmus the families Cyrtodesmidae and Doratodes- 
midae are established. 
Family HAPLOSOMID^ Silvestri, 1895. 
Under this name Sig. Silvestri includes a miscellaneous assemblage 
of all known diplopod genera with nineteen segments. Even Para- 
doxosoma Daday is among the number, although a family Paradoxo. 
somatidae was established six years in advance of the Haplosomidae.
