22 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 7 



Collections.— 209-34, 212-34, 213-34, 430-35, 432-35, 558-36, 

 632-37, 863-38, 881-38, Redondo Beach, California. 10 specimens. 



Length to 48 mm, width to 25 mm without lateral fibers. The 

 neuropodial setae are arranged in three tiers, arranged about as follows : 

 2 stout superior (pi. 1, fig. 1), 5 median slenderer than those in the 

 superior rank (pi. 1, fig. 2), 7-20 inferior much paler and slenderer 

 setae. Those in the superior and median tiers are falcate, copper colored, 

 those in the inferior tier are as shown in figure 4, and are pale yellow. 

 In some specimens the pilosity is very extensive (pi. 1, fig. 5), in others 

 almost absent, because of the sloughing off of the pilose hood. The 

 longer dorsal setae have a hooked tip (pi. 1, fig. 3). 



Dorsal cirri are long, slender; ventral cirri are pale, tapering, ex- 

 tending distally about as far as the middle of the ventralmost setae or 

 somewhat beyond. 



The description of A. cryptommata Essenberg agrees well with that 

 of J. japonica save for the statement that in the former the elytra are 

 squarish along their medial margins. The shape of the elytra is similar, 

 however, if the inner edge be slightly cut away, as sometimes happens 

 when the dorsal felt is cut apart. 



Distribution. — Northeast and northwest Pacific; California south 

 to Ecuador. In depths to 75 fms. 



Aphrodita parva Moore 



Plate 1, Figs. 9, 10 



Aphrodita parva Moore, 1905, pp. 529-532, pi. 34, figs. 3-7; 1908, p. 

 339; 1910, pp. 385-386; Tread well, 1914, p. 178; Berkeley, 

 1923, p. 211. 



Collections.— 740-37, 899-38. About 25 specimens. 



Length 8 to 24 mm; width to 15 mm without lateral fibers. The 

 dorsum is dark drab, completely covered with fibers and debris, neither 

 notopodial nor neuropodial setae projecting. Lateral fibers inconspicu- 

 ous. The superior neuropodial setae are pilose distally (pi. 1, fig. 10). 

 The inferior neuropodial setae have a minute spur at their widest part 

 (pi. 1, fig. 9). Some of them have a delicate dehiscent hood. 



Distribution. — Northeast Pacific, Gulf of Georgia to western 

 Mexico. In depths from 3 to 667 fms.
