birds of South Africa and those of Britain is sufficiently pro- 

 nounced, and even the fish-fauna of the two is divergent, yet 

 in the group of the AnneHds not a few are common to both 

 regions, and as knowledge extends such mav even be found 

 more general than is supposed. 



In the following report, a few collected by the "Challenger" are 

 indicated in their proper places — occasionally with additional 

 information. The references under the various species have 

 been selected as those which, in all probability, may be most 

 useful.

This widely distributed species, which ranges from the Cape 

 to St. Paul, is characterised, when contrasted with the British, 

 by the proportionally longer, more finely spinose and more 

 flattened body. The dorsal surface is convex, the ventral flat- 

 tened. The head bears a caruncle, consisting of an elevated 

 keel and a flat band, which reaches to the eighth segment. In 

 front of it is a short and somewhat conical tentacle with an eye 

 on each side of its base. A pair of more minute and in some 

 almost confluent eyes occur on the ventral surface of the 

 cephalic ridge. In front of the puckered opening of the mouth 

 are two kidney-shaped pads, separated by a deep median fissure, 

 and which may be homologous with the palpi of other families. 

 These pads are probably of some importance as pivots during 

 the action of the buccal apparatus. The arborescent branchiae 

 are purplish with the elliptical or sub-oval tips pale reddish, and 

 each complete row generally consists of eleven trunks. The 

 dorsal bristles are of two kinds — smooth and crenated in the 

 fissure, whilst all the bifid ventral bristles are smooth. The 

 size of the largest example agreed with those found by the 

 " Challenger " under stones between tide marks at Sea Point, 

 Cape Town, and the British EtipJirosyne foliosa has the same habi- 

 tat in the Channel Islands, The pigment in both probably 

 subserves other functions than either ornament or protection.
