quently no depth nor locality can he given. The animal 

 itself is linear, and the body has ahout 98 segments. The 

 dorsal surface is light brown and slightly iridescent, while 

 the ventral surface is darker in colour, and each segment 

 has minute dark spots. No groove is present in the ventral 

 surface of the specimen, and tiie dorsal lamellae of the feet, 

 moreover, were not so prominent as is mentioned in the 

 Monograph. However, it (dorsal lamella) was considerably 

 larger than the ventral lamella, and no spines were seen ou 

 the spinigerous papilla at its outer border. The Monograph 

 mentions that the spinigerous papilla may bear a few (about 

 two) smooth tapering bristles, and Malmgren adds that 

 the large, more or less horizontal dorsal cirrus is elliptico- 

 subrectaiigular or uuequully reniform. . The ventral bristles 

 spring from the tip of the lobcj and are characteristic of the 

 species. 



The Monograph states that this species is more sluggish 

 than the ordinary examples of the Phyllodocidae, and, when 

 irritated, coils its body in a somewhat stiff manner. There is 

 no mention of this sj)ecies in the Reports of the * Challenger ' 

 PLxpedition ; but iu Prof. Izuka^s wox^iNotophjUumjopomcuinj 

 Maren., is described, and this species appears to approach the 

 northern species very closely. 



From the Monograph its habitat is given as : — Shetland 

 {J. G. J.) ; Lamlash Bay, Arran [Dr. Ilowden) ; Bay of 

 Galway, Ireland {Dr. E. P. Wright) ; St. Andrews i3ay, 

 deep-sea fishing-boats {E. M.) ; common in dredgings, 

 Plymouth {Allen) ; Norway {CErsted, Sars, Norman, and 

 Koren); Sweden; Adriatic («Sa>-5) ; Marseilles {Marion).

Fifty-eight complete and an infinite number of fragments 

 of this species were obtained in four hauls. The hauls were 

 8100, 2 miles E.N.E. of Bams Ness, at a depth of 100 m.; 

 l.'>2, off Ardmore Point, at a depth of 180 m. ; 82<35, at 

 Station 41 A, 50° 48' N., 1° 19' E., at a depth of 94 m. ; and 

 72, 3 miles west of Tarbet Ness, at a depth of 24 fathoms. 



This annelid usually inhabits regions where there is grey 

 mud or clay, and off the western coast of Britain has been 

 found at depths varying from 4-125 fathoms. One or two 

 have been found on the ver'^e of extreme low water in Ard-
