MARINE ZOOLOGY 



1 6. Spirorbis nautilotdes^ Link. 



A minute species with coiled tube, the 

 coils being arranged in the same plane. 

 Attached to weed, corallines, and many 

 other objects. Very common. Hastings. 



17. Spirorbis lucidus, Montagu.* 

 Common. Hastings. 



1 8. Spirorbis communis. t 

 Brighton. 



19. Filograna implexa. 



Animal secreting a long filiform, cal- 

 careous tube. The individuals are social, 

 the associated tubes being packed together 

 parallel-wise in considerable masses. 

 Trawled ; not very common. Hastings. 



ARENICOLID^ 



20. Arenicola piscatorum. 



The ' fisherman's worm ' is about 6 

 inches long, brown, and with a large head 

 which is covered with spiny tubercles. 

 The dendriform gills are arranged along 

 each side of the middle portion of the 

 body. Very common upon the sand shore, 

 where it burrows deeply. Hastings. 



CIRRATULID.S 



21. Cirratu/a, sp. 

 Hastings. 



CH.STOPTERID.S 



22. Cheetopterus insignis, Baird. 



This species forms a tough parchment- 

 like tube, 1 2 inches in length, by f inch in 

 diameter. The tubes are trawled upon 

 the Diamond Ground, but so far as the 

 writer has observed are always empty. 

 Not uncommon. Hastings. 



23. Nereis margaritacea. 



Animal about 4 inches long, of a 

 pearly lustre, and flattened dorsally and 

 ventrally. It is nearly always found in- 

 habiting the same shell with the trawled 

 hermit crab ; this however is not the case 

 with the smaller, shore-frequenting hermit 

 crab. Common. Hastings. 



24. Nereis fimbriata, Mttller.* 

 Bexhill. 



25- Nereis brevimanus. t 

 Brighton. 



26. Nereis longissima. t

POLYZOA 



ECTOPROCTA 



CTMNOL&MATA 



CHEILOSTOMATA 



1. /Etea anguina, Linnaeus. 



A minute species with zoarium of ivory 

 whiteness, usually found trailing over sea- 

 weed, and giving off from enlargements of 

 the creeping stem or stolon, short tubular 

 zocecia, curved and expanded in the upper 

 part, and with aperture terminal. The 

 zooecium bears some fancied resemblance 

 to the arched head and neck of the hooded 

 cobra. From moderately deep water. Not 

 uncommon. Hastings. 



2. jEtea recta, Hincks. 



Resembling jE. anguina but with zooe- 

 cium straight, and with longer aperture. 

 Common upon rock and shells from the 

 Diamond Ground and deep water. Hast- 

 ings. 



EUCRATIID^E 



3. Eucratea che/ata, Linnaeus. 



This dainty little species might well 

 receive the popular appellation of the little 

 glass slipper, for the zocecia strikingly re- 

 semble a series of semi-transparent little 

 slippers united together toe and heel by 

 short prolongations. A free form, long, 

 and rather tubular in the lower part of the 

 zooecium also occurs at Hastings, but is 

 comparatively rare. Type, upon weed and 

 coralline stems ; somewhat rare. Hastings. 



4. Gemellaria loricata, Linnasus. 

 Colonies some 7 inches in height, 



seaweed-like and of a dull buff or grey 

 colour. Stems formed of matted fibres, and 

 the branches of zocecia somewhat ovate, 

 but tapering downwards, and arranged back 

 to back. Not uncommon. Hastings.
