A HISTORY OF ESSEX 



8. Nephthys cteca (Fabr.). 



Much larger than the above and not so 

 common, but occurs in sandy mud at the 

 mouth of the Colne and off Harwich. 



9. Phyllodoce maculata (?) (Johnston). 



Only one specimen has been found, which 

 occurred in the sandy mud at low water off 

 Harwich. 



10. Glycera capitata(l) (Oerst.). 

 Apparently rare in the Essex district since I 



have found only two specimens which oc- 

 curred in the mud of the Crouch at Burnham 

 and corresponded with the figures given at 

 plate xvb of the Brit. Mus. Catalogue (1865). 



1 1 . Syllis armillaris (Mull.). 



Possibly not uncommon but easily over- 

 looked from being so small. It is interesting 

 from the manner in which it divides into two 

 or more individuals. 



12. Goniada maculata (?) (Grube). 



Only one specimen was found in the sandy 

 mud near the mouth of the Colne. It seems 

 to agree with the description in the Brit. 

 Mus. Catalogue (1865). 



13. Nerine foliosa (Aud. & M. Edw.). 

 Occurs in the sandy mud near the mouth 



of the Colne near low water, but it is almost 

 impossible to obtain perfect specimens. 



14. Nerine cirratulus (Delle Chiaje). 

 Common in sandy gravel near Mersea 



stones much above low water mark. 



15. Scoloplos armiger (O. F. Muller). 

 Occurs in considerable numbers in gravelly 



sand at the mouth of the Colne. 



1 6. Cirratulus cirratus (Malmgren). 



Found in sandy mud near low water mark 

 at the mouth of the Colne, but not common, 

 and the specimens small. 



17. Flabelligera affinis (Sars). 



Though all my specimens have been ob- 

 tained in the Orwell, yet when floating as it 

 often does in the tide it must have sometimes 

 passed into Essex. 



1 8. Notomastus latericeus (Sars). 



Occurs in sandy mud near the mouth of 

 the Colne and off Harwich. 



19. Arenicola marina, Linn. 



This is very abundant in sandy gravel near 

 the mouth of the Colne and off Harwich, and 

 dug extensively for bait. 



20. Lanice conchi/ega, Pall. 



I have found this over nearly the whole 

 district. It occurs in large numbers on the 

 east side of the Colne below Brightlingsea 

 near low water mark. 



21. Amphitrite Johnston! (Holmgren). 

 Common in particular places in sandy mud 



near the mouth of the Colne. 



22. Nicolea zostericola, Orst. 



This used to be very common in the 

 Orwell just outside Essex, but was not found 

 in 1901. 



23. Polycirrus aurantiacus, Grube. 



This is common at the mouth of the Colne 

 in sandy gravel at about half-tide level, but 

 only in restricted areas, where it occurs along 

 with Phascolosoma. It seems surprising that 

 such a long tender animal can move about in 

 such coarse rough material. 



24. Melinna cristata, Sars. 



Occurs in the sandy mud near the mouth 

 of the Colne, but all the specimens found 

 were of small size. 



25. Pectinaria belgica, Pallas. 



I have never found this alive, but empty 

 tubes are common off Mersea. 



26. Terebe Hides strcemii. 



This interesting species, of which only one 

 specimen had been found in British waters, 

 over a hundred years ago, in Scotland, used to 

 be fairly common in the Orwell near Pin Mill, 

 a few miles outside Essex, but was rare in 

 1901. 



27. Sabellaria spinulosa, Leuck. 



I have dredged this off Harwich and off the 

 Colne, and it must be common in many other 

 places in the more open water but not in the 

 estuaries. It builds the sandy tubes locally 

 called ross, 



28. Sabella pavonina, Sav. 



This is more or less common over the 

 whole district and occurs in enormous num- 

 bers along the east side of the Colne above 

 Brightlingsea Creek at the level of low water. 

 Some years ago I found in that district a con- 

 siderable number of what was either a dwarfed 

 variety or a somewhat different species not 

 met with lately. 



II. GEPHYREA 



I. Phascolosoma, sp. 



I have never found this except in one small 

 tract of sandy gravel at about half-tide level
