PAUROPODA. 
convex, all the sensory hairs jointed or feathered, and the legs project- 
ing somewhat beyond the margins of the segments. American spec - 
mens are gregarious and have always been found on or under rotting 
limbs; they are not strongly convex like Glomeridse ; the fourth and 
fifth pairs of sensory hairs are smooth, and the legs never project be- 
yond tho margins of the segments. Nearly all the other characters 
mentioned by Latzel might from their nature be supposed to be generic. 
10. Eurypauropus cycliger Latzel. Known only from Austio-Hungary. 
Latzel’s description seems to indicate that the dorsal hooks are not pres- 
ent, and that there are many sensory hairs to each segment, which 
would point to generic distinctness frem spinosus, 
11. Eurypauropus PociLLiFER Silvestri. Known only from Italy. The dor- 
sal spines are said to be in rows, which makes the generic designation 
somewhat doubtful, but whether the rows are longitudinal or horizontal 
is not stated. The dorsal tubercles are said to be "'in medio excavatisp 
but the meaning of this is not clear. The structures in question when 
viewed from above appear hollow in A. spmosus ; how they differ in E. 
pocillifer is not explained. 
12. Trachypauropus GLOMERioiDEs Tcemocsvary. This has been reduced by 
Daday to a synonym of Eurypauropus cycliger Ltz., but if the charac- 
ters noticed under that species are really present at least the genus will 
will probably be maintained. 
13. Cyphopauropus margaritaceus (Toemoesvary). According to the descrip- 
tion this species differs from the others in the following generic charac- 
ters ; Body elongate, three times as long as broad ; dorsum densely 
punctate and tuberculate, the margins with rough tubercles and a row 
of setse ; first segment triangular ; fifth segment (only?) sinuate at the 
sides; seventh segment sinuate at apex, near the anus with three long 
hairs: legs 6-7 jointed, the tarsus 2-3 articulate, with a single claw. 
Known only from eastern Hungary, and said to have the habit of a small 
species of Glomeris. 
14. Acopauropus ornatus (Latzel). Specimens collected by Latzel were 
among Haase’s collection acquired by the Berlin Museum (No. 1645). 
They are generically distinct from Eurypauropus spinosus in that the 
dorsum is longitudinally carinate, the carime bordered by regular rows 
of fine tubercles and surmounted by a row of flattened hooks which ap- 
pear only on the carinae and lateral margins, where they are expanded 
into large, obovate, leaf-like, reticulate appendages; sixth and seventh 
segments not concealed, the sixth dorsall}^ unicarinate, the seventh pro- 
duced into a narrow apical process truncate at the end ; margins of seg- 
ments not notched; sensory hairs of fourth segment hot clavate. The 
dorsal parts are here much less strongly chitinized than in Eury- 
pauropus, and the habit is so different as to suggest the idea that were a 
larger series of forms known this genus would have been placed in a 
subfamily or family distinct from the Eurypauropodidse. 
15. Brachypauropus hamiger Latzel. This most interesting creature 
measures .4 mm. by .2 mm, and is the smallest of the Progoneata ; it 
has a tiansverse row of four hamules on each segment, and two such 
rows on the first. Latzel found it but once, and its structure was so del- 
icate that drawings were not attempted.
