in the Catalogue ami was dredged in mud in deep water ofF 

 Cumbrae by Dr. D. Uobcrtson. It appears to be an Axio- 

 thella. The second (also called Clymene lumbricoides) was 

 procured by Laughrin in 40 fathoms oH" the coast of Cornwall. 

 In this the posterior margin of the cephalic rim has very few 

 crenationsj and two papilhe occur in the central line in front. 

 It also resembles an A.viuthella. 



Since the date of the Catalogue various species have been 

 added to the Jiritish fauna by the ex[)editions of Dr. Gayn 

 Jeffreys. Messrs. Cunningham and llamage mentioned 

 Nicuinac/ie lumbricaIes = N. maculata, Arwidsson, and Aaio- 

 thea cattnuia, both of which had long i)een familiar. 



No mention of the family occurs ni the riymouth list of 

 1904, but two are entered by Major ]^lwes in the littoral 

 fauna of Torquay, viz. L'lijinciie oerstedi (?), Claparede, and 

 Lcioclione clijpeata, De St. Joseph. 



The rirst example of the group is Rhodine loveni, Malmgren, 

 which was dredged off the Hebrides by Dr. Gwyn Jeffreys 

 in June and July 1866 ; whilst abroad it occurs in Swedish 

 waters and the Atlantic coast of the United States. As, 

 however, only fragments have been procured in the British 

 seas, the following summary is partly drawn from Arwidssou's"^ 

 description. 



The head is bluntly conical in front, forming a short cone 

 when viewed from the dorsum and a flattened beak when 

 seen laterally. The nuchal grooves run forward by the side 

 of the short keel and then curve outward and slightly back- 

 ward to the margin. When the proboscis is partly extruded 

 it forms a larger anterior and a smaller posterior region, each 

 with papilhe. The body is about 4i inches in length, and 

 may have forty bristled segments, the first of which is not 

 separated from the peristomial and is comparatively long ; 

 the second is shorter, and so with the third and fourth. 

 These bear only bristles. The fifth and sixth are nearly 

 equal in depth and bear in the middle bristles and hooks. 

 The eighth has its foot rather in front of the middle, whilst 

 in the connate eighth and ninth segments the foot is near 

 the segment-junction. The segments 11 to 15 are nearly 

 equal, with the foot near the posterior border of each ; but the 

 sixteenth and seventeenth are longer, the latter being nearly 

 twice as long as the eleventh. The last bristled segment 

 ends in a free collar, from the centre of which a short 

 segment with a constriction posteriorly projects, the region 

 beyond expanding into the smooth anal cup with its central
