 found under stones [Shetlands, Irish Sea, North Sea, Dinard, Plymoutii]. The Valorous 

 expedition [No 83] obtained it in 20 fethoms (shell sand), 60 fathoms (sand and shell), and 

 80 fathoms off the coast of Greenland ; the Porcupine (No. 82) at 60-160 fathoms, cast of 

 Cape Gatte ; the Norwegian North Atlantic expedition [Hansen, No. 36] at depths of from

 on gravel and sand, and at 219 fathoms on mud. 



Evarne impar (Tabl(! VI.). Specimens were obtained on the fine sand 

 of Grounds I. and VII., ou the fine gravel of Ground XIV., to the west 

 of the Eddystone, and on the Prawle Stony Ground. The species was 

 nowhere numerous. 



DiSTiiiiiUTiON. Davis Straits (M'Intosh, Valorous, No. 83), Iceland, Shetland, North 

 Norway, British Coasts, North France {Jide Michaelsen). Outside Gibraltar (358 fathoms, 

 M'Intosh, Porcupine). Shore (Saint-Joseph, No. 102, and Hornell, No. 49) to 567 fathoms 

 {Porcupine, No. 82). 



Polynoe scolopendrinn . Mr. Hodgson has identified a single specimen 

 of this species in haul 54 on the fine sand of Ground VII. 



Distribution. M'Intosh (No. 84) states that the species occurs from Shetland to the 

 Channel Islands, generally in tubes of 2'erebella nebulosa, and that it is abundant on the 

 shore in the Hebrides (No. 81). Saint-Joseph (No. 102) found it on the shore and also in 

 deeper water at Dinard. Irish Sea (Hornell). Adriatic, Trieste, Egypt {fide Cams, 

 No. 14). 



Halosydna gelatinosa. A single specimen on the typical coarse 

 gravel, Ground IX. (haul 93). The species is not unfrequeutly taken in 

 the Plymouth district in shallower water. It occurs on the shore at 

 low-water. 



Distribution. West Norway, British Coasts, North-AVcst France, west of Morocco 

 {fide Michaelsen, No. 79). Hornell (No. 49) records it from the shore at Puffin Island 

 (Irish Sea). 



Hermadion assimile. A single specimen in haul 92 on the fine sand 



of the inner trawling ground (Ground I.). 



Distribution. M'Intosh (No. 84) records the species from St. Andrews and from the 

 Porcupine dredgings olf the west of Ireland, south of England, and Spanish coast. 

 Hornell (No. 49) took it in the Irish Sea in depths of 11 and 21 fathoms amongst the 

 spines of Echinus esculentus. 



Acholoe astericola is by no means uncommon in the ambulacral groove 



of Astropecten irregularis. Its occurrence is incompletely recorded in 



Table VI. 



Distribution. Hornell (No. 49) gives the distribution from the Mediterranean to 

 Galway, Marenzeller found it in the Mediterranean on Astropecten atiranliacus, on A. 

 bispinosus, A. platy acanthus, and A. pentacanthus. 



Hyalinoecia tubicola. Chart X. This species is abundant on the 

 coarse gravel mixed with sand and mud in the neighbourhood of the 

 Eddystone, where it forms one of the typical and characteristic features 

 of the fauna. It is specially numerous on Ground IX., which exhibits
