Remarks . This species is in general appearance rather similar 
to P. oculatus and P. simulans, but it is sharply distinguished by 
a number of characters: much shorter eyes, very short hairs in alj 
rows on the head, the shape of the anal plate, the bulb on the 
third pair of tactile setæ, and several other but less important fea¬ 
tures. 
Spurious or insufficiently described Species of Pauropus. 
1. Pauropus filiformis Cook. In an „Anmerkung“ on p. 27 
in his great work Latzel describes a form which he names P. Hux- 
leyi var. filiformis] he found it in Austria. The form measures 
•75 mm. in length and is more siender than P. Huxleyi , further- 
more he says on the third pair of tactile setæ, that it is „gewohn- 
lich ziemlich deutlich gegen das Ende oder vor dem Ende verdickt, 
so dass es dunnkeulenfortnig aussieht. . .“. But if this statement 
be correct, he has commixed at least two species, and his descrip- 
tion of the form is very incomplete. It is certain that he has 
based the „variety“ filiformis on animals belonging to species very 
distant from P. Huxleyi, but it is impossible to refer with certainty 
any of my European species to his , filiformis 11, , and this being pro- 
bably based on at least two species it will be best to drop the 
name for ever. — Mr. O. F. Cook has („Brandtia“ VI, p. 31) 
established the species P. filiformis on Latzel’s description, writing 
that the differences pointed out by Latzel are „numerous and de- 
finable“, but they can not be used as characters for a species. 
2. Pauropus Lubbockii Packard (Proc. Boston Soc. Nat. Hist. 
XIII, p. 409; Amer. Naturalist IV, p. 621). Captured in Massa- 
chusetts, U. S. Nobody has been able to recognize this species 
with certainty. With interrogation it was referred to P. Huxleyi
