CAMBALOID MILLIPEDS LOOMIS 39 



the dorsal crests. On the anterior segments the pore swellings are 

 conic and oblique to the sides of the body, while on the caudal segments 

 they are lower, more flattened, and nearly parallel with the body. 

 On the penultimate and antepenultimate segments the lateral carinas 

 are no larger than the dorsal crests, but on the next segment in front 

 the differentiation is evident. Below the poriferous carinae are 12 to 

 14 crests decreasing in size toward the legs, even the upper ones less 

 conspicuous than the dorsal crests. 



Last segment smooth, the apex rounded, not exceeding the valves. 



Preanal scale large, about half as long as broad ; the tab processes 

 at the lateral angles relatively large and conspicuous. 



Gonopods as shown in figure 11, « and 6. 



First pair of male legs with the last joint bluntly and obliquely 

 truncated on the inner side halfway to the base, the truncation deeply 

 excavated, claws lacking. Legs 4 to 7 inclusive with the outer joint 

 densely hairy beneath; behind the gonopods to the end of the body 

 the five outer joints also are densely hairy beneath, those at rear 

 somewhat less so than those in front. Female legs less hairy. Legs 

 5 to 7 of the males with the fourth joint bearing a large, hairy -tipped, 

 conic prominence near the distal end on the under side; the fifth 

 joint of these legs sometimes with a similar but smaller lobe. 



Segments 6 and 7 of the males with the margin surrounding the 

 genital opening greatly elevated mesially, equaling the top of the first 

 joint of the adjacent legs. 



CAMBALA CRISTULA, new species 



Figure 12 



Many specimens collected at Etowah, Tenn. (type locality), No- 

 vember 1, 1929, and a male and a female collected at Adams Run, 

 S. C, October 11, 1929, by Dr. O. F. Cook. The type is a male, 

 U.S.N.M. no. 1305. 



This species is closely related to annulata but distinguished from 

 it by the stouter body, a female specimen 44 mm long being 3 mm 

 broad; the much less prominent poriferous keels; the smaller pro- 

 duced posterior angles of segment 1; lateral keel on each side of 

 segment 4 no larger than the four dorsal crests, while in annulata 

 there usually is a decided contrast; the presence of a lobe on the 

 ventral surface of the fifth joint of legs 5, 6, and 7 of the males, a 

 condition infrequently observed in annulata^ but like annulata^ with 

 a large lobe beneath the fourth joint. 



The principal difference, however, is found in the structure of the 

 gonopods (fig. 12, a and h) as a comparison of the drawings of the 

 tvro species will show. 



Leg 1 of the male is shown in figure 12, c.
