CAMBALOID MILLIPEDS LOOMIS 37 



First pair of male legs 6-jointed and without a claw at tip. The 

 fifth, sixth, and seventh male legs have a large lobe on the ventral 

 side of the fourth joint and sometimes one on the fifth joint also. 



KEY TO THE SPECIES OF CAMBALA 



1. Body small and slender, not exceeding 20 mm in length and 0.8 



mm in width ; dorsal crests beginning on segment 4 and ending 



on antepenultimate segment texana, new species 



Body larger and stouter ; crests beginning on segment 2 and end- 

 ing on penultimate segment 2 



2. Body of intermediate size, 25 to 38 mm long and 1.2 to 2 mm 



broad ; color light yellowish brown minor Bollman 



Body considerably larger, 44 mm or more in length ; color defi- 

 nitely darker brown 3 



3. Body 18 or 19 times as long as broad ; segment 1 with posterior 



angles produced backward ; poriferous keels very strongly de- 

 veloped annulata ( Say) 



Body decidedly stouter, 14 to 15 times as long as broad ; segment 1 

 with posterior angles less produced backward ; poriferous keels 

 much less prominent; gonopods differing in a number of par- 

 ticulars, as shown in the drawings cristula, new species

Specimens of this species were collected between Roan Mountain and 

 Elizabethton, Tenn., in October 1928 and between Marshall and Hot 

 Springs, N. C, in October 1929 by O. F. Cook. The species has been re- 

 ported from nearly all the Southeastern States and from Kentucky, but 

 it now seems likely that at least two species, annulata and cristula, 

 were confused, and the value of these older records must now be 

 shared by these two species, though it is usually not definitely certain 

 to which form specific records apply. The specimens here described 

 and illustrated are believed to represent the typical annulata of Say, 

 inasmuch as they are the only ones studied that have the poriferous 

 carinae distinctly "pyriform" as stated in the original description. 

 Bollman reported this species from Indiana and Arkansas, but later 

 he designated the specimens as a subspecies of annulata on account 

 of their smaller size and lighter color. It is proposed herein to 

 elevate this subspecies to full specific rank.
