between Stimpson's Lcpidoiiotiis sfinitccta" than is hinted at in 

 the Challenger volume,! so that this author's title may yet claim 

 priority. Kinberg's examples came from the Cape as well as 

 Port Natal, Schmarda's from Table Bay, while Stimpson pro- 

 cured his from Simon's Bay, and the present examples were got 

 between tide marks at St, James', in False Bay. 



The examples from the "Challenger" were larger than those of 

 the present series, a male measuring 36 mm. 



The head agrees generally with the type in Lcpidoiiotus. The 

 median tentacle is somewhat longer than the palpi, dilated at 

 the tip, and with a filiform termination. The lateral tentacles, 

 though small, correspond in structure. In the males, the ventral 

 papilhe of the body are longer than in the females, in which 

 they are tulip-shaped. 



Schmarda's figures, presumably from life, though details are 

 somewhat doubtful on this head, show the middle of the dorsum as 

 quite bare from the head to the tail, yet he does not indicate 

 the structure of the head thus exposed, the yellowish hue of 

 the dorsum passing forward to the base of the tentacles, a con- 

 dition at variance with nature. On the whole, the structure of 

 the foot, the scales and the bristles, as shown by this author, do 

 not offer any objection to the union of the species with 

 Kinberg's. Schmarda observes that the proboscis is brown and 

 yellow, and that the intestine (which he figures) has sixteen 

 pairs of caeca. 



The scales are generally covered with sand-grains, mud, 

 thread-like alga^, Infusoria like Salpiiiga'ca, with, here and there, 

 an example of Loxosonia. 



The species seems to be widely distributed round South 

 African shores, and takes the place, for example, of such a form 

 as Lepidouotiis chiva, IMontagu, in Britain. As Kinberg observes, 

 the South African form is probably included in the Aphrodita 

 squanuitd of Pallas, who conjoined with it the European 

 species as figured by Baster. 



Baron de St. Joseph, who has done such excellent work 

 amongst the Annelids of the French coast, was of opinion that 

 this species was only a variety of Lipidoiiofiis cUiva, Montagu, 

 but as shown in the Annals of Natural History in 1898,! a con- 

 siderable margin for variation will be necessary before this can 

 be established. De St. Joseph's main reasons for the union of 

 the species are ( i ) that the figure of the scale in the 

 "Challenger" volume exactly agrees with Lcpidoiiotus clava, 

 and (2) that m the same work it has been shown that the palpi 

 are papillose, a feature, also, characteristic of Lcpidoiiotus dura.
