Oi-)t;iinecl between tide marks, St. James', in False Bay. 

 A lai\Lie Eunice, apparently common at the Cape, stretching 

 to 1 80 mm. in spirit, and in life probably considerably beyond 

 that measurement. 



In dealing with spirit-specimens it is difficult to make out 

 resemblances in colour, but in the examples from the Cape the 

 tints of most are recognizable. The cupreous or brownish red 

 and somewhat dappled hue, and the white bands anteriorly 

 I'eadilv distinguish it. 



The head, tentacles, bristles, branchiae, and teeth all conform 

 to the type. The simple bristles, which are modified winged 

 bristles, are marked under a moderately high power by minute 

 and slightly oblique lines (probably extending from the wings), 

 and thus the surface is file-like, a condition figured by Schmarda 

 in his Eunice niacrohniiichid, which is here considered to be 

 the same species. The wing is very narrow, but the lines from 

 the serrations on the edge pass inwards as described. These 

 bristles have long tapering tips. The compound bristles with 

 bifid tips were few in the examples procured b}' the " Challenger," 

 and consequently an average example from the anterior region 

 of the body is given in Plate 11. fig. 14. The brush-shaped 

 bristles have rather wide teeth with slender filaments distally, 

 and a long filament at one end (Plate II. fig. 15). The posterior 

 hooks correspond with those figured in the "Challenger." 



The dental apparatus also coincides with the type, the great 

 dental plates each having 5 teeth ; the azygos 6 ; the left anterior 

 lateral 4 teeth ; and the right 7 teeth. Each of the two 

 accessory pieces attached to the latter has a horny dental 

 edge. The posterior appendages and the mandibles are typical. 

 The branchiae commence in these examples on the sixth foot 

 as a minute simple filament, and the organs become pectinate 

 on the nth foot. The pinna3 reach the number of 16 or 17, 

 but they probably vary, and may increase with age. They are 

 continued almost to the tip of the tail, which has two cirri 

 beneath the vent. 



The food in the alimentary tract consisted of portions of a 

 Polyzoon with long vibracula, spicules of sponges, numerous 

 diatoms, fragments of alg^e and spores. In others, fragments of 

 a larger sea-weed occurred, besides smaller branched forms en- 

 crusted with large diatoms and mingled with mud rich in Fora- 

 minifera, bristles of annelids, crustacean hairs, sponge-spicules 

 and radiolarians. 



Though Schmarda's description and figures of his Eunice 

 uiacrobyauchia leave much to be desired, yet, it is evident he 

 refers to this species, and Ehlers is inclined to the same view. 

 Thus he describes, under the specific characters, the semi- 

 cylindrical body as cupreous, or reddish brown, and, further.
