unpaired ovary is present, and that the ova pass in strings into the 

 oviducts (formerly " ovaries "). 



The author confirms a part of Thorell's observations upon the 

 connexion of the female generative organs, and, by the discovery of 

 the hitherto overlooked external genital aperture of the female, 

 brings back these organs to the general type of the whole order. 



In all the males observed he describes an unpaired testis, and 

 represents the envelope of the spermatophores as secreted by the 

 wall of the whole of the seminal duct. In the spermatophore itself 

 he recognizes more layers than Thorell. He describes the type on 

 which the nervous system is constructed, and, in opposition to Buch- 

 holz, asserts the presence of olfactory nodes. — -Anzeiger AJcad.

Notice of a new Pauropod. 



Mr. J. A. Ryder described a new myriopod which he had recently 

 discovered, and which turned out to be nearly allied to the form de- 

 scribed by Sir John Lubbock under the name of Pauropus. The 

 specimens which the speaker bad obtained were five in number and 

 had but six segments, fewer than any other known member of the 

 group, whilst the number of pairs of legs was nine, the same as in 

 Pauropus, which is very strong evidence that the specimens are 

 adults. The following characterization of the genus and species 

 was proposed : — 



Eur y pauropus sjilnosus, gen. et sp. nov. 



Body-segments six in number, sixth exceedingly rudimentary ; 

 antennae five-jointed ; legs in nine pairs, equidistant ; tergal sclerites 

 laterally expanded so as to conceal the legs almost entirely when the 

 animal is viewed from above, and covered with fine tubercles which 

 are joined to each other by raised lines ; appressed curved spines are 

 scattered over their surface in less number, and also fringe their 

 margins, being disposed at regular intervals ; the spines and lines 

 give the dorsal surface of the little creature a slightly silky lustre 

 when viewed with reflected light. Colour a delicate light brown. 

 Mouth-organs the same as in the first-described genus. No evidence 

 of eyes could be detected. Length -^ inch ; width about y 1 ^ inch. 

 Habitat in Fairmount Park, Philadelphia, east aud west of Schu} r l- 

 kill, under decaying wood. 



The tergal sclerites are much thicker than in Pauropus, having 

 the characteristic brown colour of chitin when viewed with trans- 

 mitted light. The antennas have the terminal globular hyaline body 

 with a long pedicle, as in Pauropus pedunculatus. The type is the 

 most distinct form discovered since the detection of the first known 

 representatives in England in 1866, and also extends the geogra- 

 phical range of the family, and does much towards fully establishing 

 the Pauropoda as a distinct order of myriopods. — Proc. Acad. Nat.
