on dorsum niul voiitiuni. This unique colour is no doubt due 

 to the scorching tlie animals received in the laboratory fire, 

 for in living examples tiie animals are pale pink or skin- 

 coloured. Tlie species is not uncommon in the stomach ofc" 

 the cod and flounder, and, when plentiful, forms abundant 

 food-supj)ly for these fishes. The range of the species is 

 wide, for, besides being j)revalent in British waters, it has 

 been found off the Siberian coast ( Wirdn) and at other parts 

 of the world. Allied forms, like those of the 'Challenger' 

 collection, frequent shallow water. No mention of this 

 species is made by Izuka, and no German report has come 

 to notice. 



The head is conical, but the four tentacles at the tip are 

 just like little warts. No eyes are distinct, and the proboscis, 

 although extended in three forms, lias been injured and 

 shows the various pieces cf armature very poorly. The feet, 

 although considerably dried, conform with the type-slides, 

 and the bristles are quite characteristic of the species. None 

 of the specimens were mature, but, according to various 

 observers, the females at least become mature about June or 

 July, and although no ripe males have been recorded, it is 

 probable that both sexes mature simultaneously. 



Prof. M'Intosh says "It is remarkable to find such slight 

 differences between the Glycinde tnfida of the ' Challenger ' 

 from Charlotte Sound, New Zealand, and the British form." 



Family Glyceridae. 



Genus Glycera, Savigny, 1820. 



Glycera lapidum^ De Quatrefages, 1843. 



In haul 111 one incomplete specimen of this form was 

 dredged along with Lumhriconereis gracilis ^t a station \ mile 

 N.W. of Gluss Island, Shetland, at a depth of 16 fathoms. 

 The animal is about 1^ inches long and has al)Out sixty 

 bristled segments, each segment being three-ringed, and all 

 appearing equal. Although only one example appears in the 

 collection, this species is by no means scarce or uncommon, 

 as the habitat given in Prof. M'Intosh's ' Monograph ' will 

 show. It is found in deep as well as in shallow water, 

 abounds in British seas, and extends to Norway, shores of 

 North America, west coast of North America, Azores, 

 Setubal, Mediterranean, but is not recorded in * Challenger ' 

 Report nor from Japan. 



The head tapers to a blunt point, from which four short 

 slender tentacles arise, while the body tapers more posteriorly
