developed as in the next species. The anal segment bears at apex above 
two rounded, apparently chitinous prominences ; below it has a slightly 
tridentate structure to which are articulated two fusiform processes differ- 
ing greatly from the figures of those of huxleyi as given by Lubbock 
and Kenyon ; length 1.3 mm., width about. 3 mm. Five specimens of this 
species were collected between Huntington and Cold Spring, Long 
Island, in May 1893. 
4. Pauropus bollmani, sp. n. Specimens in the National Museum collected 
by Bollman, and doubtless the same as those reported by him from 
Bloomington have the dorsal hairs, especially the anterior, much more 
strongly clavate than those of the other species, or than the figures of 
Lubbock and Kenyon. There seems to be but one rounded and flattened 
superior knob on the anal segment, and the inferior processes are more 
slender and closer together than in P, impar, though the condition of 
the specimens is not such as to give confidence in this observation. The 
rami of the stout branch are about equal in length; larger specimens 
are about i mm. long. All are of a distinctly brownish tinge, but may 
have become stained from the rubber corks. 
5. Pauropus filiformis, sp. n. Described from Austria by Latzel as P . 
huxleyi var. filiformis. According to Latzel the differences are con- 
stant, and as they are numerous and definable the reason for the 
varietal designation is not clear. 
6. Stylopauropus atomus, sp. n. Differing from St. pedunculatus at least 
in the much smaller size, as mature individuals of both sexes are 
only .55 mm. long. The flagella of the antennse have a distinct, smooth, 
and somewhat enlarged base as in the species of Pauropus, while in 
pedunculatus, according to the diagrams of Lubbock and Kenyon 
(copy ?) the flagella are ringed nearly or quite to the base. The stout 
branch is nearly as long as the other, broader distad, and has the corner 
, cut away and the appendages attached as in the figures oi pedunculatus. 
Three mature specimens were found on rotting bark under fallen leaves 
in dry woods near Huntington in the present month. 
7. Stylopauropus pedunculatus (Lubbock). Reported from England, 
Austria (Latzel), Germany (Haase), and Russia (Schmidt), but it is 
doubtful whether the continental species is the same as the English. 
8. Eurypauropus spinosus Ryder. Known from Fairmount Park, Philadel- 
phia (Ryder), and from Bloomington, Indiana (Bollman). I have exam- 
ined Bollman’s specimens and cannot object to his determination, 
though certainty can hardly be reached without comparison with the 
types of spinosus or with material from the typical locality. I have 
found what seems to be spinosus in considerable quantity under bark of 
rotting poplar branches at Kirkville, Onondaga County, New York, on 
three occasions. The specimens differ from those from Indiana in being 
somewhat lighter colored and in having the dorsal hooks slightly 
less numerous. A large proportion of specimens taken in September 
were young, while in May no young were seen, 
g. Eurypauropus latzeli, sp. n. Without having seen American specimens of 
this genus Latzel has reported E. spinosus from Austro-Hungary. A 
careful study of Latzel’s description arouses the suspicion that his 
species is distinct, the following being the more important discrepan- 
cies : E. latzeh lives solitary under stones, has the segments strongly
