604 A New Genus of Minute Pauropod Myriapods. (October, 
then new species at the meeting of the Entomological Society of 
London, “ Mr. Westwood remarked that, with the exception of 
the genus Fapyx, described by Mr. Halliday, Pauropus was the 
most interesting addition to the Articulata which had been made 
for many years.” This high degree of interest attaches to the 
discovery of Pauropus on account of the remarkable characters 
which it presents, and which constitutes it one of those types 
known to systematists as synthetic or comprehensive, that is, it 
embodies characters found in several forms widely removed from 
each other in the system. In the form of the body and legs the 
creature recalls the large carnivorous myriapods or centipedes, 
whilst in the possession of a pulvillus or pad, and a claw on the 
feet, they resemble in a measure true insects; in their branched 
antennz they resemble crustaceans, and in their herbivorous hab- 
its they resemble the herbivorous, and in the distribution of the 
legs they combine characters of both the herbivorous and the 
carnivorous myriapods. 
Sir John believes, after reviewing the opinions of the most dis- 
tinguished naturalists, that the group must be considered a class 
having the same systematic value as that of similar subdivisions 
of the animal kingdom, and in view of the singular assemblage 
of characters presented by Pauropus, he thinks it necessary to 
erect a new order under the name of Pauropoda with a family 
Paurepodide ; this arrangement would then cause the class to fall 
into three apparently natural groups. 
To the three known species of the order Pauropoda, it gives us 
pleasure to add a fourth, so widely different from all others 
hitherto described as to leave no doubt as to the propriety of 
erecting a new genus for its reception. This singular form was 
discovered by myself in the month of April of the present year, 
in East Fairmount Park, in company with my friend, Mr. D. S. 
Holman. Upon that occasion five specimens were obtained, which 3 
formed the basis of the description of the genus publi.shed in the 
- Proceedings of the Academy of Natural Sciences of Philadelphia 
shortly afterwards. Not long after, in an excursion with the same 
- gentleman, I found five more specimens in West Fairmount Park, 
on the west side of the Schuylkill river, perhaps a mile from the 
first locality, which I succeeded, as stated before, in keeping alive 
until the middle of July last; having produced young whilst m
