MYRIAPODA — IUMLKMANN. 



65 



Ventral pores wanting. Presterna divided. 



Last tergum nearly as long as broad at the base, with margins 

 converging backwards, the breadth of the posterior margin being 

 less than balf the breadth of the anterior. 



Last sternum as long as broad, 

 narrow, scarcely wider at the base 

 than the preceding sternum and far 

 more narrow than the anal segment 

 — coxa? of anal legs included ; sides 

 feebly converging and slightly 

 convex ; apex truncate. 



Anal legs rather short, seven 

 jointed (coxa? included), armed with

to twelve pores, of which four to five in one row tr °j • ' 



concealed under the lateral margin of the sternum, 

 the others remaining uncovered. Another set of pores is to 

 be seen on the dorsal surface opening beneath the anterior angle 

 of the tergum and the side of its pretergum (Figs. 16 and 17.) 



Male appendages long, acuminate. Anal pores present but 

 feebly chitinized. 



This species seems nearly related with Geophilus concolor, 

 Gervais, which has a larger number of leg-bearing segments, say 

 sixty-nine to seventy-one, a cephalic plate abruptly narrowed in 

 front and no pores on the dorsal surface of the anal coxa?. Nothing 

 is known as to the structure of the mouth-parts of Gervais' 

 species.

 Genus Geomerinus, gen. nov. 



This genus, the type of which is Geomerinus cnrtipes, Haase, 

 only differs from the preceding Paehymerinua by the joints of 

 the anal legs which number six, instead of seven. Since this 

 character ranks as generic amongst the Geophilomorpha, a new 

 division has to be erected for the reception of Haase's species.
