pnvtcuuissa, though on a much larger scale than in British 

 forms. The lateral folds of the cephalic region are very 

 distinctly marked, though not long. On each side of the 

 median in front is a well marked division, followed by three 

 larger lobes which are notched in the centre. Behind are about 

 six crenations before the median dorsal furrow, with indications 

 of a tendency to form larger lobes. The median and two 

 lateral ridges are similar to those of P.pnvicnuissa. The buccal 

 and the following segments, and to some extent the vent are 

 marked by creases like hard grained morocco leather. 



The body has 21 segments besides the buccal segment and 

 the funnel. It is rare to find a complete example in Britain, 

 and only one occurs in the South African collection. The 

 funnel has from 22 to 26 teeth. 



The bristles, spines and hooks appear to be very closely 

 similar to those of the British forms though all are larger. 



The tubes are formed of fine and coarse sand grains and 

 fragments of shells — lined by secretion, and are friable whitish 

 structures. 



The preparations from the " Challenger " material were 

 labelled Pmxilla praicniiissn var. capciisis and it was the connate 

 condition of the dorsal longitudinal muscles that led to 

 separation. It is doubtful if this is sufficient to sepiU'ate forms 

 so closely resembling each other. 



The distribution of the species would seem to be very wide.

The specimens were procured at St. James', False Bay, 

 between tide-marks. Those obtained by the " Challenger " 

 were collected between tide-marks at Sea Point, near Cape 

 Town, where it was first found by Schmarda, and subsequently 

 by Kin berg. 



The largest example, including the tail, measures 105 mm. 

 in length, and it is evidently a richly coloured form. Schmarda 

 states that his were olivaceous, but in many parts were purplish 

 brown. 



The species is allied to the ordinary Sabellaria^, differing 

 from the common southern form — Sabcllaiia alvcolaia — in
