cimens the two dorsal tripes appear to be much thinner than in the 
Malayan species. A dozen of specimens was captured in Natal bay (Durban). 
The Durban-specimens fully agree in coloration as well as in structure 
with those from Banda; only the median tentacle appears to be shorter 
and does not much exceed half the length of the caruncle, whereas in 
the Banda-specimens it is nearly of the same length or somewhat longer. 
The largest specimen has a length of 18 mm.; the number of its 
segments is 23. ; 
Iphione muricata (Sav.) '). 
Two small specimens, agreeing in all regards with those from the 
Indian Ocean, were collected at Durban (Bluff). Iphione muricata has 
already been found at Djibouti by Coutière, near Mauritius by Mathieu *). 
Kinberg described an other species of this genus, Iph. spinosa *), from 
Port Natal (Durban), especially distinguished from Jph. muricata by its 
longer antennae (,basi et lobo cephalico longiores, palpos spinosos supe- 
rantes”); according to Gravier it should also be characterized by a pe- 
culiar structure of the neuropodial bristles. However it is somewhat 
dubious whether Iph. spinosa does really represent an other species *). 
Lepidonotus semitectus Stimps. ©). 
(— wahlbergi Kinb.) °). 
Of this species, that is widely distributed round the South African 
shores, specimens were collected in Table bay and near Durban. 
Scalisetosus pellucidus (Ehl.). 
(— communis (D. Ch). 
Several individuals of this species, already mentioned by Ehlers ‘) from 
Simonstown, were collected in Table bay. However, in my opinion, they 
differ somewhat from the specimina, found on the coast of Europe, by 
the structure of their dorsal bristles. According to Mc Intosh *) the dorsal 
setae do not show more than eight laciniated rows or frills, whereas — 
Claparède *) figures seven of them and St. Joseph '°) speaks of four
