NO. 14 MILLIPEDS OF WEST INDIES AND GUIANA LOOMIS 5 



pits forming a triangle, each pit containing a very fine erect sensory 

 hair ; remainder of head glabrous. 



First segment small and inconspicuous, a very narrow transverse 

 ellipse not reaching the lateral limits of the body. On either side of 

 the middle there is a very large transversely oval cluster of long erect 

 radiating hairs ; remainder of surface glabrous. Some writers appear 

 not to have noted the first segment as distinct from the second seg- 

 ment but have combined the two in describing segment i. 



Second segment with the lateral prominence on each side produced 

 forward about opposite the lateral angle of segment i. Near the pos- 

 terior margin on each side is a very narrowly oval cluster of long 

 hairs, the two dorsal clusters connected by a submarginal row of 

 much shorter depressed hairs. 



Ensuing eight segments with vestiture similar to segment 2. Seg- 

 ment 3 with the lateral prominences somewhat directed forward, but 

 on the other segments they are directed backward. Each of these 

 lateral prominences bears a dense brush of very long, barbed hairs, 

 some hairs being as long or even longer than any two segments com- 

 bined. In general, these hairs are directed obliquely backward and 

 show much less tendency to radiate in all directions than is usual in 

 this family. 



Last segment with a very large and exceedingly dense brush of 

 slender, uniformly long, straight hairs lying parallel to each other, 

 each hair with one to three tiny hooks on one side near the apex. 

 The brush of hairs is about as wide as the last segment, the sides 

 are almost parallel, and the end is squarely truncate. 



Legs rather stout; joint i as long as broad; joint 2 about half as 

 long as broad ; joint 3 longer than broad ; joints 4, 5, and 6 decreasing 

 in length ; joint 7 longer than any other joint, narrowly conical, with 

 a spine beneath the apical third which is stouter than the terminal 

 claw. Ventral-posterior face of joints i, 2, and 3 with two to five 

 short, clavate hairs in a single longitudinal series. 



Type.—U.S.'NM. no. 1084. 



LOPHOPROCTUS NIVEUS, n. sp. 



Two females were collected in dry leaf-litter near the rocky clififs 

 on the southwest coast of Beata Island, January 18, 1932. 



Diagnosis. — The smaller size, lighter color, shorter and more defi- 

 nitely radiating hairs of the lateral prominences, and the compound 

 terminal pencil of hairs distinguish this species from L. comans, the 

 only other named species in the West Indies.
