convex. Their surface is studded on the inner region with 

 rotate papilla?, some small and adpressed, others large, and 

 elevated on a pedicle. Externally are softer elongated spinose 

 papill?e, which, in shape, resemble a prickh^ pear ; margin of 

 the scale ciliated ; dorsal bristles, pale, silky, with a very 

 attenuate tip — hispid with opposite spines ; ventral bristles, dull 

 yello^ ', with simple, slightly hooked tips. 



So far as known, this form has hitherto occurred only in 

 the region mentioned, and is one of the most characteristic 

 Annelids of the Cape.

A fragmentary form, procured between tide-marks at Sea 

 Point, Cape Town, along with Sabcllaiia, Tcrebella, and Sabclla, 

 Unfortunately, the specimen had no scales, but it will be re- 

 cognized by the following features : — The head is characterised 

 by the large size of the base of the median tentacle ; the lateral 

 tentacles are short, with a filiform tip passing abruptly from the 

 nearly cylindrical organ. Palpi of moderate length, and 

 papillose. A pair of small eyes occur at the outer and posterior 

 border of the head, whilst a pair lie behind the anterior border, 

 and lateral in position. The tentacular cirri have a slight 

 enlargement below the filiform tip, and the cylindrical column 

 is papillose. The dorsal bristles end in a somewhat blunt 

 rounded process, as in Einion liispaiiica* and an allied bristle 

 is seen in Kinberg's Antiiioc pukhclla,] from the mouth of the 

 La Plata. The ventral bristles have comparatively short tips, 

 with a simple terminal hook.

Head elongated from before backwards. Two rather small 

 eyes at the posterior border and two largei- in front of the lateral 

 prominences. The tentacular and dorsal cirri have a tendency 

 to assume a fusiform condition, and all are smooth. The ven-
