Channel Islands, both in the dredge and between tide-marks. 

 Its numerous olive-brown bands and touches, white specks, 

 and size (6 to 9 inches) make it readily recognizable. The 

 occurrence of the branchicC on the 4th bristled segment, the 

 fact that their maximum development is in the anterior 

 third of the body, and that, gradually diminishing, they are 

 represented in the caudal region by a single filament as in 

 front, are also features of moment, along with the structure 

 of the bristles and hooks. The powerful ventral hooks 

 appear before the 30th bristled segment and continue to the 

 posterior end. 



As formerly pointed out, another British species is Eunice 

 v'lttata, Delle Chiaje (= E. limosa, Elilers), which occurs on 

 various parts of the British coast from the Channel Islands 

 to Polperro and Galway, It is a small species (2 to 3 inches 

 in length) with an evenly rounded snout composed of the 

 fused palpi, \^hich, however, show a deep ventral furrow. 

 The branchiae commence on the 3rd foot as a simple 

 filament ; on the 10th foot are four diA'isious ; on the 30th 

 five divisions. They then diminish so that the 40th foot 

 has only four, the obth two, and the 60th one. They are 

 absent only on the caudal segments (17 or 18). The falcate 

 bristles and the bifid crown above the great fang of the 

 posterior hooks and the dental apparatus are likewise 

 characteristic. 



The third British species is Eunice pennata, O. F. ]M. * 

 (= E. norvegica, L.), dredged off Inverary by Dr. Gwyn 

 Jeffreys. In this the fused palpi have a deep notch in front 

 and a deep groove ventrally, whilst superiorly they are 

 excavated. The branchiae commence as a short subulate 

 process on the 4th foot ; three divisions occur on the 8th 

 foot. The 12th foot has only two: those following generally 

 two, though occasionally three. Then diminishing to one, 

 they cease about the 40th foot. The highest number of 

 branchial filaments observed was four. The spines are 

 black in the adult. The ventral bristles have a short bifid 

 terminal piece considerably narrower than the dilated end 

 of the shaft. The powerful posterior hooks have a main 

 fang and a strong spike above it. The great dental plates 

 have seven teeth, the azygos (left) plate has nine. The 

 left anterior curved plate has six and the right ten teeth^ 

 and the row is continued by two separate brown denticles 

 in each case. Marenzeller has found this form in the
