spiiug. The queen survived until September following, and would 

 doubtless have lived longer had she not been neglected during a pro- 

 longed absence in summer. She outlived all her subjects, and was 

 certainly more than a year old. 



j3. Myriapoda. 



New Pauropod.* — Mr, J. A. Eyder describes a new Myriapod, 

 which is nearly allied to the form first described by Sir John Lubbock 

 under the name of Puuropus, in reference to the fewness of its feet. 

 The specimens obtained are ten in number, and have but six segments, 

 fewer than any other known member of the group, whilst the number 

 of pairs of legs is nine, the same as in Pauropus, which is very strong 

 evidence that the specimens are adults. The following characteriza- 

 tion of the genus and species is proposed : — 



Eurijixmropus spinosus, gen. et sp. nov. Body segments six in 

 number, sixth exceedingly rudimentary ; antennas five-jointed ; legs in 

 nine pairs, equidis^tant ; 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 also 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 v.U of an inch ; width about yL of an inch. Habitat in Fair- 

 mount Park, Philadelphia, east and west of Schuylkill, in moist 

 situations under sticks and decaying vegetable matter. 



The tergal sclerites are much thicker than in Pauropus, having 

 the characteristic brown colour of chitin when viewed with transmitted 

 light. The antennfe 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 repre- 

 sentatives in England in 1866, and also extends the geographical 

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

 Pauropoda as a distinct order of Myriapods.

New Division of the Tarantulida.f — Dr. Karsch proposes the 

 following division of the Tarantulida : — 



1. All the six true legs are formed in the samo way (i. e. the 

 fourth pair has no tibial joint). 



Phrynichus : — type sp. P. reniformis Linn. 



2. The legs of the fourth pair have each a single tibial joint. 

 Damon (C. L. Koch) : — type sp. D. medius Herbst. 



3. The legs of the fourth pair have two tibial joints, and tho 

 anterior one is the shorter. 



Tarantula Fabr. : — type sp. T. pumilio (C. L. Koch). 



4. There are three tibial joints. 



Charon : — type sp. Charon Grayi Gervais.
