CAMBALOID MILLIPEDS — LOOMIS 



41 



Description: Length, up to 20 mm; width, to 0.8 mm. Number 

 of segments, 45-51. 



Head with four to seven ocelli in a single series. Mentum nar- 

 rower than in annulata. Mandibulary stipe flattened, with a raised 

 rim along the lower margin. 



First segment wider than the head, providing a recess on either 

 side into which the antennae may be bent back; lateral margin 

 bordered by a very fine rim; posterior angles not produced. 



Segments 1, 2, and 3 smooth and shining, minutely and sparsely 

 granular. Crests beginning abruptly on segment 4, with four broad 

 crests on the dorsum between the scarcely more prominent poriferous 

 keels, which are represented by oval or subelliptical swellings. On 

 the side of the body below the poriferous keels there are 14 or 15 

 thinner crests. Surface of the dorsal and lateral crests and the 

 poriferous keels finely but distinctly gi*anular. Dorsal crests some- 

 times evident on the antepenultimate segment but never on the last 

 two segments.

 terior gonopods, lateral view ; c, first leg of male ; d, outer joints of sixth leg of male. 



Last segment relatively longer than in annulata^ the apex more 

 deflexed and the valves, in lateral view, more oblique. Preanal scale 

 transverse, much less rounded than in annulata. 



Gonopods and first male legs as shown in figure 13, a-c. 



Legs 5, 6, and 7 of the male with a very large process on the 

 ventral side of the fourth joint near its distal end, its apex extending 

 beyond the end of joint 6 (fig. 13, d) . 



Genus PAITEYA Chamberlin 



This genus has some affinity with Canibala as shown by the pres- 

 ence of eyes; four dorsal interporiferous crests; first male legs with 

 six joints. The size, however, is much smaller; the eyes are in two
