5G0 Trof. irintosli's Notes from the 



cirri, tlie long (18 inclies to 2 feet) body, wliicli is somewhat 

 rounded in extension, flattened in contraction, the condition 

 of the dental apparatus, and the ventral bristles, the terminal 

 part of which is long and tapered, are sufficiently charac- 

 teristic. The branchiae commence about the 21st foot, 

 attain a maximum of eight divisions, then diminisli, until 

 in front of the tail a short process of two divisions and then 

 of one occurs, the last twelve or fifteen segments being 

 devoid of them. The spines are black. 



Marph7jsa BeUii, And. & Ed., again, is rather a rare 

 British form, the only living example observed having been 

 captured in Ilerm. It is attenuated for a Eunice and is 

 6 or 7 inches long. The head is bluntly conical, with a 

 median groove inferiorly, and the tentacles are proportionally 

 long. The branchiae commence on the 14th foot and con- 

 tinue to the 34th, and the maximum number of filaments 

 appears to be about twenty-five. The number of teeth on 

 the great dental plates is about six, whilst the azygos plate 

 has seven. The living example Avas obtained between tide- 

 marks, but in the ' Porcupine ' Expedition of 1870 it was 

 dredged in 81 fathoms off Cape Finisterre. 



A species very abundant in the Channel Islands and in 

 the south of England is Lysidice ninetta, Aud. & Edwards 

 (the Leodke triantennata of Kisso). It is especially com- 

 mon in the cliinks of gneiss in the Channel Islands. Its 

 broad flattened snout with a median notch, the short 

 tentacles (a median and two lateral), aud the reddish-brown 

 body dappled with white or pale spots readily distinguish 

 it externally. 



In the same region (Guernsey) is Nemaionej'eis uniconiis, 

 Grube ^, which frequents similar fissures in gneiss between 

 tide-marks. The evenly rounded snout forming a short 

 blunt cone, the two black eyes with the short subulate 

 median tentacles between them, the form and coloration 

 of the body, the nature of the foot and its bristles, and the 

 structure of the dental apparatus are diagnostic. This form 

 diverges from Schmarda's species — procured in the Atlantic 

 ■ — in tlie smooth subulate tentacle, the form of the maxillae, 

 and in the shorter tips to the compound bristles. 



Under the Eunicea Labidognatlta nuda of Elders is Lum- 

 briconereis fragilis, O. E. JNliiller, a form which is widely 

 distributed in British waters from Shetland to the Channel 

 Islands. In this the conical head has a dimple posteriorly 

 leading into two pits with papillfe. The foot has simple
