in the United States National Museum, Washington; 6 paratypes 

 (2 99, 4 cf cf) in the Zoologisch Museum, Amsterdam; and the re- 

 maining paratypes in the collection of A. G. Humes. 



Other specimens (all from Psammocora contigua in 1 m at Ambari- 

 obe, collected during 1963).— 9 99, 8 d' cT, Sept. 6; 2 99, 2 cf d^, Sept. 

 17; and 10 99, 3 cf d', Oct. 6. 



Female. — Body (fig. 52) with broadened prosome. Length 

 (excluding setae on caudal rami) 1.25 mm (1.21-1.29 mm) and 

 greatest width 0.65 mm (0.62-0.68 mm), based on 10 specimens. 

 Katio of length to width of prosome 1.22:1. Segment of leg 1 sepa- 

 rated from head by a dorsal furrow. Epimeral areas of segments of 

 legs 1-3 expanded as shown in figure. Segment of leg 4 without such 

 expanded areas. 



Segment of leg 5 (fig. 53) 86/x x 213^- Between this segment and 

 genital segment a short ventral intersegmental sclerite. Genital seg- 

 ment wider than long, 146/i x 172jLt, broadest in its anterior half and 

 tapered posteriorly. Areas of attachment of egg sacs situated later- 

 ally (only slightly dorsally), each area (fig. 54) bearing two setae 10/x 

 and 6/i in length, with a short spinous process between them. Three 

 postgenital segments VSju x 99^, 62ju x 96iLi, and 6811 x 97jli from ante- 

 rior to posterior. Anal segment posteriorly with row of small spinules 

 laterally and ventrally on each side. 



Caudal ramus (fig. 55) moderately elongated, 92ju x 35ju in greatest 

 dimensions (77^ along inner edge, 90ju along outer edge). Katio of 

 length to width 2.63:1. Outer lateral seta 57^ long with minute bar- 

 bules; outermost terminal seta 58;^ and innermost terminal seta 75)u, 

 both with proximal hairs and distal barbules as in figures. Two long 

 median terminal setae 237/i (inner) and 146^ (outer) with proximal 

 spinules and distal barbules; these two setae mserted between dorsal 

 and ventral flaps (both with a row of slender spinules). Dorsal pedi- 

 cellate seta 37/i and naked. Dorsal surface of ramus with a few hairs 

 and two small hyaline spinules. 



Dorsal surface of prosome and urosome with scattered hairs (as in 

 figs. 52, 53) ; ventral surface of urosome sparsely ornamented. Ratio 

 of length of prosome to that of urosome 1.72:1. 



Egg sac (figs. 52, 56) attached in somewhat oblique position, with 

 posterior end lying dorsally over postgenital segments. In lateral 

 view egg sac m one female 400^ x 285)u, containmg about 12 large eggs, 

 with their diameters 117/x-130Ai. 



Rostral area (fig. 57) with broadly rounded posterior margin. 



First antenna (fig. 58) 7-segmented, with a small sclerite on third 

 segment suggesting an intercalary segment. Lengths of segments 

 (measured along their posterior nonsetiferous margins) 55^ (71m along 

 anterior margin), 62ju, 28ju, 28^, 32ju, 33ju, and 18/x, respectively.
