^ET. ]S NEW GEISTERA OF MILLIPEDS GOOK AND LOOMIS 23 



ing the sides of the body; distinctly clavate; joints from 1 to 6 gradu- 

 ally thickened; joints 2 and 6 longer than the others, subequal; joint 7 

 less than half as long as 6. 



First segment scarcely wider than the head, longer than the fol- 

 lowing segment; subhexagonal in shape, front margin longer than 

 posterior, both squarely truncate, sides broadly angulate in advance 

 •of middle and without any trace of lateral carinae. Immediately 

 behind the front margin and on either side of the middle the segment 

 is very strongly inflated but lacks a true impressed median sulcus; 

 surface pubescent but not tuberculate. 



Second segment with strong, forwardly directed lateral carinae; 

 a single transverse series of about six large raised tubercles across 

 the middle. 



Following segments have the anterior subsegments conspicuously 

 exposed and widely separating the posterior subsegments so that 

 the lateral carinae are not in as continuous a series as in Brachycyhe,' 

 surface with several annular folds directed backward as they ap- 

 proach the impressed median line; edges of the folds crossed by 

 short, closely placed flutings. Posterior sub- ^^ 



segments with two transverse series of 8 to ij 

 12 rounded tubercles across the dorsum but 

 not extending to the lateral carinae; be- 

 tween the series of tubercles is a curved fur- ^^«- ^-^^^l^^^^ ''"'^^^• 

 row, directed backward on either side of 



middle; carinae of a few of the anterior segments curved forward, 

 thereafter produced laterally and on the last few segments with the 

 posterior angles more greatly produced backward; pores on the 

 middle of the outer edge of the carinae on a few of the anterior seg- 

 ments behind which they are on the posterior angle. 



Several segments before the last with the tubercles reduced in size 

 or entirely lacking, with the transverse furrow visible. 



Last segment cylindrical, as long as the two preceeding segments 

 and extending beyond the caudal angles of the penultimate segment ; 

 posterior margin truncate; surface without tubercles, but pubescent 

 and with several long hairs on the margin. Anal valves exceeding 

 the last segment; strongly and evenly inflated and bearing a few 

 stiff hairs in addition to smaller finer ones; margins meeting in a 

 deep groove. Preanal scale present, located in an excision of the 

 last segment; small, rounded in front and truncate behind, the hind 

 margin continuous with that of the last segment; smooth. 



Legs extending beyond the sides of the body ; coxae closely placed, 

 between them an erect, elongate, mushroomlike prominence with 

 the apex produced forward ; the first and second pairs of legs appear 

 to be somewhat reduced in size and slightly crassate.
