PEOM THE CAPE OF GOOD HOPE. 205 



22. LrMBRicoNEREis NARDONis, Grube. (Plate 13. fig. 22.) 

 See Ehlers, Borstenwurmerj 1868, p. 381. 



It is with some hesitation that I assign a specimen found in the same tube with the 

 preceding to this species. It is difficult to distinguish Lumbricouereidse, as a rule, 

 from one another. Almost the only difference (the only one which I can recognize) 

 between L. cocclnea and L. nardonis relates to the form of the prostomiura, Avhich 

 is subglobular in the former and subcorneal in the latter. 



Capillary setae occur in the first 46 segments, up to 7 in a fascicle. 



The two species L. coccinea and L. nardonis are associated together in the Adriatic, 

 and it would seem tliat this is also the case in Table Bay, though further observations 

 are required in confirmation of this statement. 



23. LuMBRicoNEKEis CAPENsis, Grubc. 



Lumbriconereis capensis, Grube, "Fortsetzung . . . iiber Eunicea : II. Lumbriconereidffi," Jahresber. 

 Schles. Ges. 1878 (Jhrg. 56), Breslau, 1879, p. 95. 



Probably synonymous with Z. cavifrons, Grube (' Novara ' Exped., Annel. 1867, p. 13) ; 

 it cannot be distinguished satisfactorily from Z. Dilbeni, Kinberg, 1864i. 



Six specimens from St. James, Palse Bay. One was much slenderer than the rest, 

 having 300 segments, head conical, capillary setae in about 60 segments. Another 

 shorter specimen had capillary setae (frequently 3 in a foot) in about 36 segments. 

 No compound setae. 



Another specimen (125 segments, incomplete behind) had simple curved limbate setae 

 in the first 50 setigerous segments, thereafter the hamate limbate setae. Prostomium 

 rather longer than three succeeding segments, ovate. 



24. CiREATULUs ATROCOLLARis, Grube. 



Cirratulus atrocoUaris, Grube, " Annel. Gazelle," Monatsber. Akad. Berlin, 1877, p. 536. 



Body round, smooth, and short ; segments over 200, crowded and short ; there is a 

 half-collar of black pigment on the third segment below ; length nearly 40 ram. ; 

 ventral aciculae no stronger than the dorsal, slightly curved ; aciculae absent from about 

 30 anterior segments; most of the curved ends of the aciculae are broken off; the set:n 

 are excessively brittle ; branchiae in paired acervi. 



Twelve specimens " in mud on mud-banks in the Knysna Lagoon," a large salt-water 

 lagoon formed by the sea entering the mouth of the Knysna River. 



25. ClKRATULIJS TENTACULATUS MERIDIONALIS. 



Cf. Marenzeller, Polychaten der Angra Pequena-Bucht, 1888, p. 16. 



Ventral aciculae commence at the 40th segment (52nd, Marenz.), the dorsal after 

 the 100th (184th, Marenz.) ; anterior branchial filaments numerous, forming a con- 

 tinuous transverse acervus ; length 70 mm., width 2-5-3 mm. 



Twenty-one examples between tide-marks amongst rocks at Sea Point, Table Bay.
